Authentication

+ +

RomM provides support for various forms of authentication, granting flexibility in securing access to its features.

+

Setup

+

You'll want to set the following environment variable before starting RomM:

+
    +
  • ROMM_AUTH_SECRET_KEY is required and can be generated with openssl rand -hex 32
    • +
+

Sessions

+

When the /login endpoint is called with valid credentials, a session_id is generated, stored as a cookie and sent to the browser. The same token is used to create a cache entry in Redis (or in-memory if Redis is disabled) which maps the token to the user. This way no sensitive information is stored on the client.

+

Roles

+

A user can have one of the following roles:

+
    +
  • VIEWER: Can view platforms and ROMs, download ROMs, and edit own profile
    • +
  • EDITOR: Can create/edit/delete platforms and ROMs
    • +
  • ADMIN: Can view all users, and create/edit/disable/delete users
    • +
+

As permissions are additive, editors will have all permissions of the viewer role, and admins all those of the editor role.

+

Basic Authentication

+

Requests can be made to protected API endpoints with an authorization header. The token is the base64 encoded value of username:password.

+

Example using cURL:

+
curl https://romm.local/api/platforms -H 'Authorization: Basic YWRtaW46aHVudGVyMg=='
+
+

OAuth

+

Along with the above forms of authentication, we've added an endpoint to generate expiring, scope-limited authentication tokens (/api/token). Successfully authenticating with that endpoint with return an access_token valid for 15 minutes, and a refresh_token valid for 2 weeks. The refresh_token can be used to generate a new access_token when needed.

+

The /api/token endpoint requires a username, password, and a list of scopes in the format read:roms write:roms read:platforms .... The list of scopes and endpoints are available to browse via Swagger UI or ReDoc (see next section).

+

Note: As of now, only the legacy password grant type is supported. We plan to eventually add support for Client Credentials.

+

OpenAPI

+

The API endpoints are fully documented and compliant with the OpenAPI specification. Explore the API endpoints using the Swagger UI interface at /api/docs and the ReDoc interface at /api/redoc, or view the raw JSON at /openapi.json.

+

For more information on OpenAPI, visit the OpenAPI Specification website.

+

FAQ

+

Can I disable authentication?

+

No, authentication is required and enabled by default.

+

I want to allow an EDITOR to edit ROMs but not delete them. Can I do that?

+

At this time, fine-grain control over permissions within a role is not supported. This decision was taking in order to simplify user management in the client, and authentication/permission code on the server.

+

Is authentication safe/robust? Can I trust it?

+

We've done our best to build an authentication system that is simple, clear and comprehensible. We have automated tests which verify that access is granted when it should be, and blocked when not (invalid credentials, missing permissions, expired access tokens, etc.). That being said, we welcome any reviews of our authentication and permission flows, PRs to fix issues, and new tests to cover edge cases.

+

I found an bug/issue with authentication. How do I report it?

+

Please report bugs in our authentication/permission system privately by submitting a vulnerability report.

Environment Variables

+ +

This is a complete list of available environment variables; required variables are marked with a ✓.

+ +
+

Tip

+

You can also set environment variables with a _FILE suffix, which will load the contents of the file specified in the variable into the variable without the suffix. For example, setting ROMM_AUTH_SECRET_KEY_FILE=/run/secrets/romm_auth_secret_key and creating a file with the secret key at the specified path will set ROMM_AUTH_SECRET_KEY to the contents of the file.

Generate API Keys

+ +

IGDB

+

To access the IGDB API you'll need a Twitch account and a valid phone number for 2FA verification. Up-to-date instructions are available in the IGDB API documentation. When registering your application in the Twitch Developer Portal, fill out the form like so:

+
    +
  • Name: Something unique or random like correct-horse-battery-staple or KVV8NDXMSRFJ2MRNPNRSL7GQT
    • +
  • OAuth Redirect URLs: localhost
    • +
  • Category: Application Integration
    • +
  • Client Type: Confidential
    • +
+ +
+

Important

+

The name you pick has to be unique! Picking an existing name will fail silently, with no error messages. We recommend using romm-<random hash>, like romm-3fca6fd7f94dea4a05d029f654c0c44b

+
+

Note the client ID and secret that appear on screen, and use them to set IGDB_CLIENT_ID and IGDB_CLIENT_SECRET in your environment variables.

+ + + + + + + + + + + + + +
IGDB CreationIGDB Secret
+

MobyGames

+

To access the MobyGames API, create a MobyGames account and then visit your profile page. Click the API link under your user name to sign up for an API key. Copy the key shown and use it to set MOBYGAMES_API_KEY.

+ +
+

Important

+

MobyGames API became a paid feature. Any existing key can be used as usual, but any new API key created will be under a paywall

+
+

SteamGridDB

+

To access steamGridDB API, you need to login into their website with a steam account. Once logged in, go to your API tab under the preferences page. Copy the key shown and use it to set STEAMGRIDDB_API_KEY.

+ + + + + + + + + + + + + + + + + + + + + + +

Quick Start Guide

+ +

This quick start guide will help you get a RomM instance up and running. It is split into 3 parts:

+
    +
  • Prepare
    • +
  • Build
    • +
  • Configure
    • +
+

Prepare

+

This guide will assume that you already have the following done, if not - stop here and come back when you do.

+
    +
  • Docker and Docker Compose installed
    • +
  • OpenSSL installed (optional)
    • +
  • A Twitch account (optional)
      +
    • 2-factor authentication set up on your Twitch account
      • +
    • This is required to get a developer account and an IGDB key
      • +
    +
    • +
  • A MobyGames account (optional)
    • +
  • Your ROMs organized in the correct format
    • +
+ +
+

Warning

+

Not setting up RomM with a metadata API will work for basic operation but can cause issues with, for instance, the Playnite plugin. It is recommended to setup IGDB API keys to avoid issues during setup.

+
+

Twitch and MobyGames API Keys

+

Head over to API key docs to get your Twitch and/or MobyGames keys, then come back here

+

Generating Authentication Keys

+

This step will generate a key that is used in the authorization of RomM. Without this, you will be unable to log in and use the platform

+

Run the following command in a terminal:

+
openssl rand -hex 32
+
+

Then copy the output and save it to the ROMM_AUTH_SECRET_KEY variable in the docker-compose file. It should look like this:

+
~$: openssl rand -hex 32
+03a054b6ca27e0107c5eed552ea66becd9f3a2a8a91e7595cd462a593f9ecd09
+
+

Build

+

Now that we have everything gathered, we can begin getting your instance set up!

+ +
    +
  1. Download a copy of the latest docker-compose.example.yml file from GitHub
    2. +
  2. Edit the file and modify the following values to configure the database
      +
    • MYSQL_ROOT_PASSWORD: Sets the root password of the database. Use a unique and secure password (use a password generator for simplicity)
      • +
    • MYSQL_DATABASE: Sets the database name for RomM. This can be modified - but it's not necessary
      • +
    • MYSQL_USER: User to connect to the database with. This can be modified - but it's not necessary
      • +
    • MYSQL_PASSWORD: Password for the user to connect to the database with. Use a unique and secure password (use a password generator for simplicity)
      • +
    +
    3. +
  3. Modify the following values in the environment to configure the application. -- Other values can be changed, but should not be done unless you know what you are doing, and are outside the scope of this guide
      +
    • DB_NAME: Name of the database set in the database section
      • +
    • DB_USER: Name of the user to connect to the database
      • +
    • DB_PASSWD: Password of the user to connect to the database
      • +
    +
    4. +
  4. Modify the following values in the volumes to configure the application
      +
    • /path/to/library: Path to the directory where your rom files will be stored
      • +
    • /path/to/assets: Path to the directory where you will store your saves, etc
      • +
    • /path/to/config: Path to the directory where you will store the config.yml
      • +
    +
    5. +
  5. +

    Save the file as docker-compose.yml instead of docker-compose.example.yml. It should look something like this:

    + +
    +Example Docker Compose +
    version: "3"
+
+volumes:
+    mysql_data:
+    romm_resources:
+    romm_redis_data:

+            retries: 5
+
    +
    +
    6. +
  6. +

    Open the terminal and navigate to the directory containing the docker-compose file

    +
    7. +
  7. Run docker compose up -d to kick off the docker pull. You will see it pull the container and set up the volumes and network:
    +
    +
    +
    +
    +
    +
    +
    RomM docker compose install
    +
     
    +
    +
    +
    8. +
  8. Run docker ps -f name=romm to verify that the containers are running
    9. +
  9. Open a web browser and navigate to http://localhost:8080, where you should be greeted with the RomM setup page
    10. +
  10. Go through the setup wizard, setting your admin username and password
    11. +
  11. Log in with the credentials you set in the setup flow
    12. +
+ + +

Configure

+

Now that the container is running, we will configure it by importing your ROMs

+

Uploading Your ROMs via Web Interface

+

This method is certainly viable, but not recommended if you have a lot of ROMs and/or multiple platforms. It is good for adding after the fact as your collection grows, but wouldn't be recommended for the first set up, nor for multi-file ROMs

+
    +
  1. Log into RomM with your user credentials
    2. +
  2. Navigate to Library -> Upload ROMs
    3. +
  3. Select the platform, then click ADD ROMs and select the ROMs you want to upload in the file selector that appears
    4. +
  4. Click UPLOAD to begin uploading the ROMs
    5. +
  5. Repeat for all the roms/platforms you have
    6. +
+

upload dialog

+

Importing Your ROMs via Scanner

+

This method is generally the fastest and recommended for first time setup

+
    +
  1. Stop your RomM instance. docker compose down if you are in the terminal and directory containing the docker-compose file, otherwise docker stop romm
    2. +
  2. Go to the library folder created by RomM, set in the docker-compose file under :/romm/library and create a folder named roms
    3. +
  3. Copy your platform folders/rom files into the roms folder you created
    4. +
  4. Start the RomM instance back up. docker compose up -d if you are in the terminal and directory containing the docker-compose file, otherwise docker start romm
    5. +
  5. Log into RomM with your user credentials
    6. +
  6. Navigate to Library -> Scan
    7. +
  7. The system will now begin scanning the rom files and applying metadata to them. You can click on any of the items that it has tagged to see the metadata it pulled without having to stop the scan
    8. +
  8. After the scan completes, click the RomM logo to go back to the main screen. You should see the platforms and recent games it has scanned. You are now ready to rock and RomM! +```

Scheduled Tasks

+ +

Scheduled tasks

+

Scheduled tasks can be enabled and configured with the following environment variables:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
VariableDescriptionValue
ENABLE_SCHEDULED_RESCANEnable scheduled re-scanning of librarytrue

ENABLE_SCHEDULED_UPDATE_MAME_XMLEnable scheduled updating of MAME XML indextrue
SCHEDULED_UPDATE_MAME_XML_CRONCron expression for scheduled updating of MAME XML"0 5 * * *"
+

Scheduled re-scan

+

Users can opt to enable scheduled re-scans, and set the interval using Cron notation. Not that the scan will not completely re-scan every file, only catching those which have been added/updated.

+

Switch titleDB update

+

Support was added for Nintendo Switch ROMs with filenames using the titleid/programid format (e.g. 0100000000010000.xci). If a file under the switch folder matches the regex, the scanner will use the index to attempt to match it to a game. If a match is found, the IGDB handler will use the matched name as the search term.

+

The associated task updates the /fixtures/switch_titledb.json file at a regular interval to support new game releases.

+

MAME XML update

+

Support was also added for MAME arcade games with shortcode names (e.g. actionhw.zip -> ACTION HOLLYWOOD), and works in the same way as the TitleID matcher (without the regex).

+

The associated task updates the /fixtures/mame.xml file at a regular interval to support updates to the library.

+

File system watcher

+

RomM can also monitor the filesystem for events (files created/moved/deleted) and schedules a re-scan of the platform (or entire library is a new platform was added).

+

The watcher can be enabled and configured with the following environment variables:

+ + + + + + + + + + + + + + + + + + + + +
VariableDescriptionValue
ENABLE_RESCAN_ON_FILESYSTEM_CHANGEEnable re-scanning of library when filesystem changestrue
RESCAN_ON_FILESYSTEM_CHANGE_DELAYDelay in minutes before re-scanning library when filesystem changes5
+

The watcher will monitor the /library/roms folder for changes to the filesystem, such as files being added, moved or deleted. It will ignore certain events (like modifying the file content or metadata), and will skip default OS files (like .DS_Store on mac).

+

When a change is detected, a scan will be scheduled for sometime in the future (default 5 minutes). If other events are triggered between now and the time at which the scan starts, more platforms will be added to the scan list (or the scan may switch to a full scan). This is done to reduce the number of tasks scheduled when many big changes happen to the library (mass upload, new mount, etc.)

Upgrading to 3.0

+ +

Version 3.0 of RomM introduces a number of breaking changes aimed at improving performance and usability, which will require some users to make specific changes before upgrading to ensure compatibility and to take full advantage of the new features.

+

All of the following changes are reflected in the example docker-compose.yml file, which has been simplified greatly. Please read this entire file carefully, as failing to do so may cause RomM to become inaccessible or unresponsive.

+

Dropped support for SQLite

+

We're removed support for SQLite as we've faced a number of engineering issues with it in the past, and MariaDB has proven more stable and robust. If you currently use SQLite, we'll automatically migrate your data from SQLite to MariaDB, but you'll first need to make the following changes before upgrading to the latest image.

+

In your environment variables, change ROMM_DB_DRIVER to mariadb (or remove it completely as it's no longer needed). You'll then want to add the following environment variables:

+
- DB_HOST=mariadb
+- DB_PORT=3306
+- DB_NAME=romm # Should match MYSQL_DATABASE in mariadb
+- DB_USER=romm-user # Should match MYSQL_USER in mariadb
+- DB_PASSWD= # Should match MYSQL_PASSWORD in mariadb
+
+

To setup a new MariaDB container, have a look at the example docker-compose.yml file.

+

Authentication as standard

+

To support new features like EmulatorJS and saves/states management, we've decided to require authentication for all users. Anyone currently running RomM with authentication disabled will need to remove the ROMM_AUTH_ENABLED environment variable and add the following ones:

+
- ROMM_AUTH_SECRET_KEY= # Generate a key with `openssl rand -hex 32`
+
+

We understand that this requirement for authentication might conflict with the way some users currently share their collection with others (unrestricted access for all). However, given the exciting new features we've built, and the ones we're looking to build in the near future, we feel this is the right decision for the project.

+

Redis is now built-in

+

As Redis is required for authentication to work, we've integrated it directly into the docker image. If you're currently running the experimental Redis container, you can remove it, along with these environment variables:

+
- ENABLE_EXPERIMENTAL_REDIS
+- REDIS_HOST
+- REDIS_PORT
+
+

Configuration folder

+

Mounting the config.yml file is now done by mounting a config folder.. Place your existing config.yml file inside a folder and bind it to /romm/config:

+
- /path/to/config:/romm/config
+
+

Updated config.example.yml

+

Support for saves, states and screenshots

+

This version introduces preliminary support for uploading/downloading saves, states and screenshots (read more about it in the 3.0 release notes). We've added a new volume mapping for these types of files called assets, which you'll want to bind to a local folder (or volume) so they'll persist. In your volumes section, add the following mapping, where /path/to/assets/ is some folder where you'll want to store these assets (and make sure that folder exists):

+
- /path/to/assets:/romm/assets
+
+

We recommend creating a folder next to your library/the one mapped to /romm/library in order to keep all your RomM files in the same place.

FAQs

+ +

Why is not PSP emulation enabled if EmulatorJS supports it?

+

PSP emulation with the PPSSPP core requires special setup with a reverse proxy, or launching Chrome browser with the --disable-web-security and --enable-features=SharedArrayBuffer flags, which WE STRONGLY DISCOURAGE as it disables important security features.

+

When will the next version of RomM be available?

+

When it's ready.

+

When will the version after that one release?

+

After the upcoming version is released.

+

When will X feature be available?

+

Sometime between now and the heat death of the universe.

+

When will version x.x.x of RomM (or any of the RomM clients/apps/plugins) be released?

+

Same as above question.

OIDC Setup With Authelia

+

A quick rundown of the technologies

+

What is Authelia?

+

Authelia is an open-source authentication and authorization server providing two-factor authentication and single sign-on (SSO) for your applications via a web portal. It acts as a companion for reverse proxies by allowing, denying, or redirecting requests. Authelia can be deployed alongside your other services to centralize identity management.

+

What is OAuth2?

+

OAuth2 (Open Authorization 2.0) is an industry-standard protocol for authorization. It allows applications (clients) to gain limited access to user accounts on an HTTP service without sharing the user’s credentials. Instead, it uses access tokens to facilitate secure interactions. OAuth2 is commonly used in scenarios where users need to authenticate via a third-party service.

+

What is OpenID Connect (OIDC)?

+

OIDC (OpenID Connect) is an identity layer built on top of OAuth2. While OAuth2 primarily handles authorization, OIDC adds authentication, enabling applications to verify a user’s identity and obtain profile information. This makes OIDC suitable for SSO solutions, where user identity is central to access management.

+

Setting up a Provider and Application in Authelia

+

Step 1: Install and Configure Authelia

+

Before setting up a provider and app, ensure that Authelia is installed and running by following the getting started and OIDC provider guides.

+

Step 2: Add a client

+

In Authelia's configuration.yml, under identity_providers → oidc → clients, add a new entry:

+
    +
  • A random client_id and client_secret +
    • +
  • public should be set to false.
    • +
  • redirect_uris should include your RomM instance's URL + /api/oauth/openid (e.g., http://romm.host.local/api/oauth/openid).
    • +
  • scopes includes openid, email and profile.
    • +
  • token_endpoint_auth_method should be set to client_secret_basic.
    • +
  • userinfo_signed_response_alg should be set to none.
    • +
+

Refer to the official docs for more details.

+

This entry should look like this:

+
#identity_providers:
+#  oidc:
+#    clients:
+- client_id: "<randomly_generated>" # read above for how generate
+  client_name: "RomM" # will be displayed in Authelia to users
+  client_secret: "$pbkdf2-sha512$randomly_generated" # read above for how generate
+  public: false
+  authorization_policy: "two_factor" # or one_factor, depending on your needs
+  grant_types:
+      - authorization_code
+  redirect_uris:
+      - "http://romm.host.local/api/oauth/openid"
+  scopes:
+      - "openid"
+      - "email"
+      - "profile"
+  userinfo_signed_response_alg: "none"
+  token_endpoint_auth_method: "client_secret_basic"
+
+

Step 3: Configure RomM Environment Variables

+

To enable OIDC authentication in RomM, you need to set the following environment variables:

+
    +
  • OIDC_ENABLED: Set to true to enable OIDC authentication.
    • +
  • OIDC_PROVIDER: The lowercase name of the provider (authelia).
    • +
  • OIDC_CLIENT_ID: The client ID copied from the Authelia application.
    • +
  • OIDC_CLIENT_SECRET: The generated output from Random Password.
    • +
  • OIDC_REDIRECT_URI: The redirect URI configured in the Authelia provider, in the format http://romm.host.local/api/oauth/openid.

OIDC Setup With Authentik

+

A quick rundown of the technologies

+

What is Authentik?

+

Authentik is an open-source identity provider (IdP) designed to manage authentication, authorization, and user management across applications. It supports modern authentication protocols and provides tools to simplify integration, including single sign-on (SSO), multi-factor authentication (MFA), and auditing capabilities. Authentik can be deployed alongside your other services to centralize identity management.

+

What is OAuth2?

+

OAuth2 (Open Authorization 2.0) is an industry-standard protocol for authorization. It allows applications (clients) to gain limited access to user accounts on an HTTP service without sharing the user’s credentials. Instead, it uses access tokens to facilitate secure interactions. OAuth2 is commonly used in scenarios where users need to authenticate via a third-party service.

+

What is OpenID Connect (OIDC)?

+

OIDC (OpenID Connect) is an identity layer built on top of OAuth2. While OAuth2 primarily handles authorization, OIDC adds authentication, enabling applications to verify a user’s identity and obtain profile information. This makes OIDC suitable for SSO solutions, where user identity is central to access management.

+

Setting up a Provider and Application in Authentik

+

Step 1: Install and Configure Authentik

+

Before setting up a provider and app, ensure that Authentik is installed and running by following the official installation guide..

+
    +
  1. Access Authentik via its web interface.
    2. +
  2. Log in as an administrator.
    3. +
  3. Navigate to the “Admin Interface” to configure the necessary components.
    4. +
+

Authentik user dashboard

+

Step 2: Create a Provider

+

A provider in Authentik acts as the bridge between RomM and Authentik.

+
    +
  1. Navigate to Providers:
      +
    • Go to the "Providers" section in the Authentik admin interface.
      • +
    +
    2. +
  2. Create a New Provider:
      +
    • Click on “Create” and choose the protocol (e.g., “OIDC Provider”). + Create a new provider
      • +
    +
    3. +
  3. Select "OAuth2/OpenID Provider" + Select OAuth2 provider
    4. +
  4. Configure Provider Settings:
      +
    • Name: Assign a unique name to the provider (e.g., "RomM OIDC Provider").
      • +
    • Authorization flow: Select implicit consent.
      • +
    • Redirect URIs: Add your RomM instance's URL + /api/oauth/openid (e.g., http://romm.host.local/api/oauth/openid).
      • +
    +
    5. +
  5. Copy the Client ID and Secret:
      +
    • You'll need these to set OIDC_CLIENT_ID and OIDC_CLIENT_SECRET in your RomM instance. + Provider settings
      • +
    +
    6. +
  6. Click Create.
    7. +
+

Step 3: Register an Application

+

An app in Authentik represents the external service (in our case RomM) that will use the provider for authentication.

+
    +
  1. Navigate to Applications:
      +
    • Go to the "Applications" section in the admin interface. + Applications
      • +
    +
    2. +
  2. Create a New Application:
      +
    • Click on “Create” and configure the app settings: - Name: Provide a recognizable name (e.g., "RomM"). - Slug: Create a unique identifier for the app (e.g., romm). - Provider: Link the app to the previously created provider, "RomM OIDC Provider". + New application
      • +
    +
    3. +
  3. Click Create.
    4. +
+

Step 4: Configure RomM Environment Variables

+

To enable OIDC authentication in RomM, you need to set the following environment variables:

+
    +
  • OIDC_ENABLED: Set to true to enable OIDC authentication.
    • +
  • OIDC_PROVIDER: The lowercase name of the provider (authentik).
    • +
  • OIDC_CLIENT_ID: The client ID copied from the Authentik application.
    • +
  • OIDC_CLIENT_SECRET: The client secret copied from the Authentik application.
    • +
  • OIDC_REDIRECT_URI: The redirect URI configured in the Authentik provider, in the format http://romm.host.local/api/oauth/openid.
    • +
  • OIDC_SERVER_APPLICATION_URL: The URL of the Authentik application, e.g., http://authentik.host.local/application/o/romm.
    • +
+

Step 5: Set your Email in RomM

+

In RomM, open your user profile and set your email address. This email has to match your user email in Authentik.

+

Set email

+

Step 6: Test the Integration

+

After configuring the environment variables, restart (or stop and remove) your RomM instance and navigate to the login page. You should see an option to log in using OIDC. Click on the OIDC button, and you'll be redirected to Authentik for authentication. Once authenticated, you'll be redirected back to RomM.

OIDC Setup With Pocket ID

+

A quick rundown of the technologies

+

What is Pocket ID?

+

Pocket ID is a simple OIDC provider that allows users to authenticate with their passkeys to your services.

+

The goal of Pocket ID is to be a simple and easy-to-use. There are other self-hosted OIDC providers like Keycloak or ORY Hydra but they are often too complex for simple use cases.

+

Additionally, what makes Pocket ID special is that it only supports passkey authentication, which means you don’t need a password.

+

What is OAuth2?

+

OAuth2 (Open Authorization 2.0) is an industry-standard protocol for authorization. It allows applications (clients) to gain limited access to user accounts on an HTTP service without sharing the user’s credentials. Instead, it uses access tokens to facilitate secure interactions. OAuth2 is commonly used in scenarios where users need to authenticate via a third-party service.

+

What is OpenID Connect (OIDC)?

+

While OAuth2 primarily handles authorization, OIDC adds authentication, enabling applications to verify a user’s identity and obtain profile information. This makes OIDC suitable for SSO solutions, where user identity is central to access management.

+

Setting up a client in Pocket ID

+

Step 1: Install and Configure Pocket ID

+

Before setting up the OIDC client, ensure that Pocket ID is installed and running by following the setup guide.

+

Step 2: Add a client

+

Once you have logged in and configured a PassKey you now need to create an OIDC client, this will let Pocket ID know about the application that needs to be configured, and will give you the relevant keys to add to the RomM compose file.

+
    +
  • Make sure within Application Configuration that "Emails Verified" is ticked, most OIDC apps will need this.
    • +
  • Go to OIDC Client
    • +
  • Click Add OIDC Client
      +
    • Name: RomM
      • +
    • Callback URLs: https://{host}/api/oauth/openid
      • +
    +
    • +
  • Click Save
    • +
  • Stay on this page, you will be shown your client secret only THIS time.
    • +
+

Step 3: Configure RomM Environment Variables

+

To enable OIDC authentication in RomM, you need to set the following environment variables:

+
    +
  • OIDC_ENABLED: Set to true to enable OIDC authentication.
    • +
  • OIDC_PROVIDER: The lowercase name of the provider (pocketid).
    • +
  • OIDC_CLIENT_ID: The client ID copied from the Pocket ID application
    • +
  • OIDC_CLIENT_SECRET: The client secret that is showing within your Pocket ID application.
    • +
  • OIDC_REDIRECT_URI: The redirect URI configured in the Pocket ID provider, in the format https://{host}/api/oauth/openid.
    • +
  • OIDC_SERVER_APPLICATION_URL: The authorization URL for you Pocket ID instance, e.g. https://id.host.local/authorize.
    • +
+

Step 4: Set your Email in RomM

+

In RomM, open your user profile and set your email address. This email has to match your user email in Pocket ID.

+

Set email

+

Step 5: Test the Integration

+ + + + + + + + +

Custom Platforms

+ +

While RomM supports every platform listed in the Supported Platforms page, the list is not exhaustive, and you may have ROMs in your library for other platforms. To load those files into RomM, place them in a folder for each platform, and give it a name that's all lowercase, with - to separate words, and with no white spaces. For example, pocket-challenge-v2 would map to Pocket Challenge V2, and display the default platform icon in the app.

+

Furthermore, only a portion of the supported platforms have custom icons built-in. If your library has platforms that aren't listed in the platforms icons list, RomM will display a default fallback icon.

+

If you'd like to load your own custom icons for missing platforms, you can mount /var/www/html/assets/platforms to some local folder and place all of your custom .ico platform icons in there. You'll also want to download the ones provided in this project and place them in the same folder. If you'd like to use your own icons for platforms already supported by RomM, just replace the file with another using the exact same name.

+

The name of the .ico file should match the slug of the platform on IGDB. For example, the URL for the AmstradCPC is https://www.igdb.com/platforms/acpc, so the filename should be acpc.ico.

+

EmulatorJS Player

+ +

EmulatorJS is a web-based emulator for various system; that is, it allows you to run old games in your web browser. It's based on Emscripten, which is a toolchain for compiling C and C++ code to WebAssembly.

+ +
+

Warning

+

Due to a change by Apple in iOS 18.2, emulation is severely limited, and likely non-functional, on iOS devices.

+
+ +
+

Warning

+

PSP emulation with the PPSSPP core requires special setup with a reverse proxy, or launching Chrome browser with the --disable-web-security and --enable-features=SharedArrayBuffer flags, which WE STRONGLY DISCOURAGE as it disables important security features.

+
+ +
+

Warning

+

Emulation is a complex and resource-intensive process. As such, it may not work well in all browser, especially older or less powerful ones. If you're having trouble running a game, try using a different browser or device.

+
+

Loading saves and states

+

Our integration with EmulatorJS automates the process of loading and saving save files and save states. Before starting the game, select a save and/or state file to load (if one is available). Anytime you save the game (or create a save state), the save and state files stored with RomM will be updated, so there's no need to manually download or upload them.

+

Synology Setup

+ +

Prerequisites

+

This guide assumes you're familiar with Docker and have basic knowledge of server management. You'll need:

+
    +
  • A Synology NAS or similar server
    • +
  • Docker installed
    • +
  • Basic command line knowledge
    • +
  • Access to manage network settings
    • +
+

Setup Process

+

1. Folder Structure Setup

+

ROM Storage Folders

+

Create the following directory structure for game assets and configuration:

+
mkdir -p /volume1/data/media/games/assets
+mkdir -p /volume1/data/media/games/config
+
+

ROM Library Structure

+

RomM requires a very specific folder structure for rom files:

+
mkdir -p /volume1/data/media/games/library/roms
+mkdir -p /volume1/data/media/games/library/bios
+
+

Note: For supported platforms and their specific folder names, refer to the official RomM wiki.

+

Docker Data Folders

+

Create these folders for project and container data:

+
mkdir -p /volume1/docker/romm-project/
+mkdir -p /volume1/docker/romm/resources
+mkdir -p /volume1/docker/romm/redis-data
+mkdir -p /volume1/docker/mariadb-romm
+
+

2. Network Bridge Setup

+

Create a new network bridge named rommbridge following standard Docker networking practices. You can use this guide for reference.

+

3. Key Generation

+

Authentication Key

+

Generate your authentication key using:

+
openssl rand -hex 32
+> 03a054b6ca27e0107c5eed552ea66bacd9f3a2a8a91e7595cd462a593f9ecd09
+
+

Save the output - you'll need it for the ROMM_AUTH_SECRET_KEY in your configuration.

+

API Integration Setup

+

RomM currently supports 3 metadata sources: IGDB, MobyGames and SteamGridDB. Follow the dedicated wiki page for API key generation to set up your API keys. We recommend setting up IGDG at the minimum.

+

4. MariaDB Configuration

+ +
+

Important

+
    +
  • This guide uses a dedicated MariaDB container for RomM, but you can use an existing MariaDB instance if preferred
    • +
  • We're using MariaDB version 10.7 for compatibility
    • +
  • The container uses port 3306 internally, mapped to 3309 externally
    • +
  • A simplified health check is implemented for stability
    • +
+
+

5. Docker Compose Configuration

+

Create a docker-compose.yml file with the following content:

+ +
+Example Docker Compose +
version: "3"
+
+volumes:
+    mysql_data:
+
+services:
+    romm:
+        image: rommapp/romm:latest
+        container_name: romm
+        restart: unless-stopped
+        environment:
+            - DB_HOST=romm-db
+            - DB_NAME=romm # Should match MARIADB_DATABASE in mariadb
+            - DB_USER=romm-user # Should match MARIADB_USER in mariadb
+            - DB_PASSWD= # Should match MARIADB_PASSWORD in mariadb
+            - ROMM_AUTH_SECRET_KEY= # Generate a key with `openssl rand -hex 32`
+            - IGDB_CLIENT_ID= # Generate an ID and SECRET in IGDB
+            - IGDB_CLIENT_SECRET= # https://api-docs.igdb.com/#account-creation
+            - MOBYGAMES_API_KEY= # https://www.mobygames.com/info/api/
+            - STEAMGRIDDB_API_KEY= # https://github.com/rommapp/romm/wiki/Generate-API-Keys#steamgriddb
+        volumes:
+            - /volume1/docker/romm/resources:/romm/resources
+            - /volume1/docker/romm/redis-data:/redis-data
+            - /volume1/data/media/games/library:/romm/library
+            - /volume1/data/media/games/assets:/romm/assets
+            - /volume1/data/media/games/config:/romm/config
+        ports:
+            - 7676:8080
+        network_mode: rommbridge
+        depends_on:
+            romm-db:
+                condition: service_healthy
+                restart: true
+
+    mariadb-romm:
+        image: mariadb:latest
+        container_name: mariadb-romm
+        restart: unless-stopped
+        environment:
+            - MARIADB_ROOT_PASSWORD= # Use a unique, secure password
+            - MARIADB_DATABASE=romm
+            - MARIADB_USER=romm-user
+            - MARIADB_PASSWORD=
+        ports:
+            - 3309:3306
+        network_mode: rommbridge
+        volumes:
+            - /volume1/docker/mariadb-romm:/var/lib/mysql
+        healthcheck:
+            test: ["CMD", "healthcheck.sh", "--connect", "--innodb_initialized"]
+            start_period: 30s
+            start_interval: 10s
+            interval: 10s
+            timeout: 5s
+            retries: 5
+
+
+

6. Initial Launch

+
    +
  1. Start the containers using Docker Compose
    2. +
  2. Be patient! The container can take a few minutes to setup on first launch
    3. +
  3. Monitor progress through container logs
    4. +
  4. Access RomM through your browser at http://your-server-ip:7676
    5. +
+ +
+

Important

+
    +
  • Replace placeholder values (UIDs, GIDs, passwords, API keys) with your own
    • +
  • Ensure proper permissions on all created directories
    • +
  • Back up your configuration after successful setup
    • +
  • Monitor logs during initial startup for any errors
    • +
+
+

Troubleshooting

+
    +
  • If the web interface shows "page not found," wait for initial setup to complete
    • +
  • For database connection issues, verify MariaDB container health status
    • +
  • Check logs for both containers if experiencing issues
    • +
  • Ensure all volumes are properly mounted with correct permissions
    • +

Tinfoil Integration

+ +

This will help you configure the Tinfoil integration for your Switch to work with your RomM library.

+

drawing

+

Prepare

+

Please note down the following in order to make this as smooth as possible, as well as some pre-reqs:

+
    +
  • RomM updated to at least 3.5.0
    • +
  • Add DISABLE_DOWNLOAD_ENDPOINT_AUTH=true to your environment variables and restart the container
    • +
  • The URL you use to access RomM
      +
    • This can either be http or https
      • +
    • The system will prefer local access though to avoid reverse proxy issues
      • +
    +
    • +
  • Feed URL: /api/tinfoil/feed
    • +
  • The username and password you use to login to RomM
    • +
+

Configure

+

Now it's time to configure your switch - Please follow the steps, this will assume you have Tinfoil installed and know how to use the basic functions of it.

+
    +
  1. Open Tinfoil and go to File Browser
    2. +
  2. Scroll over to the selection and press - in order to access the new menu.
    3. +
  3. Enter these Options
      +
    • Protocol - http or https depending on your connection
      • +
    • Host - Host of your RomM instance
      • +
    • Port - Port of your RomM Instance
      • +
    • Path - /api/tinfoil/feed
      • +
    • Username - Username of your RomM instance
      • +
    • Password - Password of your RomM instance
      • +
    • Title - Free text title, make it whatever you want.
      • +
    • Enabled - Yes
      • +
    +
    4. +
  4. Press X to save
    5. +
  5. Now close out of Tinfoil and go back in, so it can scan the TitleIDs - if everything is correct you will have this custom motd: + " RomM Switch Library"
    6. +
+

Now you will be able to see the files in "New Games" tab of Tinfoil OR you can access it within the "File Browser" section that you setup earlier.

+

Image of Tinfoil

+

Additional

+

It didn't pull anything through to "New Games" and has not parsed any information about the titles?!

+

That would be because the filename it has tried to pull had no TitleID (Improvement to RomM coming soon ™)

+

Make sure the filename has the TitleID within the title like this: +TitleID

+

Once this is done, the next time Tinfoil is opened it is always parsed and re-scanned.

TrueNAS Setup

+ +

Prerequisites

+

This guide assumes you're familiar with Docker and have basic knowledge of TrueNAS. You'll need:

+ +

Setup Process

+ +

Step 1: Navigate to RomM app

+

Navigate to the App Catalog via Apps (Left navigation bar) -> Discover Apps -> RomM -> Install

+

RomM app

+

Step 2: Installation configuration

+

Step through the installation UI. You will need to supply various credentials per the Quick Start Guide. Most of the default values will work.

+

Note: You will likely want to set certain Storage Configurations to a Dataset within TrueNAS, such as your RomM Library and Assets storage. If you do this, ensure you provide ACL access to the UserID specified above (default: 568, apps user).

+

RomM Library Example

+

Step 3: Save your configuration

+

Save, and you're done! If the app will not boot, refer to Troubleshooting or head on over to the Discord.

+

Install via YAML

+

This installation path should only be used in the event that there is a bug with installing through the App Catalog, or you wish to have more flexibility than is provided by the installation UI.

+

Step 1: Navigate to YAML install

+

Navigate to the Install via YAML page via Apps (Left navigation bar) -> Discover Apps -> Install via YAML

+

Install via YAML

+

Step 2: Paste in the following YML

+

Replace any empty values with credentials you've created per the Quick Start Guide.

Step 3: Save the configuration

+

Save, and you're done! If the app will not boot, refer to Troubleshooting or head on over to the Discord.

+

Troubleshooting

+

General

+
    +
  • Ensure you have replaced empty values (UIDs, GIDs, passwords, API keys) with your own
    • +
  • Ensure proper permissions are applied within TrueNAS
    • +
  • Monitor logs via the app bash terminal during for any errors if the app is encountering issues
    • +
+

Specific Issues

+

Permissions issues inside the docker image

+

If you are encountering permissions issues with folders internal to the docker image (not your TrueNAS dataset), consider temporarily setting the user to root (user: 0). If you do this, it is recommended you fix local file permissions via shell and return access back to a non-root user.

+

In my particular setup, I had to create a user/group in TrueNAS with uid:gid of 1000:1000 and auxiliary group apps due to hard-coded values in the RomM docker image. This resolved outstanding issues I had with my instance of RomM talking to its Redis instance.

Unraid Setup

+ +

Prerequisites

+

Before getting started, install the Community Apps plugin for Unraid.

+

Docker network

+

You'll want to create a custom bridge-type network for both containers to communicate with each other. This will prevent a number of common issues Unraid users tend to come across during setup. This can be done with the following command: docker network create romm, and you can verify it worked with docker network ls.

+

console output

+

MariaDB

+

MariaDB is required to run RomM, so install it from the plugin registry. Only the official and linuxserver versions are supported, but the official version is preferred.

+

community apps search results for MariaDB

+

Now fill in all the environment variables; descriptions of the options and sensible defaults are listed in the example docker-compose.yml file.

+ +
+

Warning

+

The network type must be set to Custom: romm

+
+

MariaDB environment variables

+

Installation

+

From the Unraid dashboard, click APPS in the navigation bar. In the search bar, search for romm, and install the app listed as "OFFICIAL". This one is maintained by our team and is the most up-to-date.

+

RomM official app

+

Configuration

+

Configure the required environment variables, ports and paths as per the example docker-compose.yml file.

+ +
+

Warning

+

The network type must also be set to Custom: romm

+
+

RomM docker tab

+

Apply the changes, then head to the DOCKER tab. You should see both containers in a running state, and can access RomM using the IP:PORT of the container (highlighted below).

+

RomM and MariaDB running

+

Updating

+

**It's strongly recommended to backup the appdata folder (or mount it in a safe location) before updating, since tearing down the container will wipe the resources (covers, screenshots, etc.)

+

Igir Collection Manager

+ +

Igir is a zero-setup ROM collection manager that sorts, filters, extracts or archives, patches, and reports on collections of any size on any OS. It can be used to rename your ROMs to match the RomM database, and to move them into a new directory structure.

+

Setup

+

Directory structure

+

The directory structure is important for running the bulk ROM renaming script. Before running the bulk ROM renaming script, set up your directories as follows:

+
.
+├── dats/ # DAT files from no-intro.org
+├── roms/ # Original ROM collection
+├── roms-unverified/ # Working copy of ROMs
+└── igir-romm-cleanup.sh
+
+

Initial Setup Steps

+
    +
  1. +

    Create a working copy of your ROMs:

    +
    cp -r roms/ roms-unverified/
+
    +

    This provides a safe working environment and allows for easy script adjustment if needed.

    +

    Download DAT Files:

    +
      +
    • For cartridge-based systems: +
      • +
    • For optical media (e.g., PlayStation):
        +
      • Visit redump.org
        • +
      • Download platform-specific DAT files
        • +
      +
      • +
    +

    Extract the DAT files to your dats directory. You can optionally extract a subset of the .dat files into the directory instead.

    +
    3. +
+

Configuration

+

Create the cleanup script igir-romm-cleanup.sh with the contents below:

+
#!/usr/bin/env bash
+set -ou pipefail
+cd "$(dirname "${0}")"
+
+INPUT_DIR=roms-unverified
+OUTPUT_DIR=roms-verified
+
+# Documentation: https://igir.io/
+# Uses dat files: https://datomatic.no-intro.org/index.php?page=download&op=daily
+time npx -y igir@latest \
+  move \
+  extract \
+  report \
+  test \
+  -d dats/ \
+  -i "${INPUT_DIR}/" \
+  -o "${OUTPUT_DIR}/{romm}/" \
+  --input-checksum-quick false \
+  --input-checksum-min CRC32 \
+  --input-checksum-max SHA256 \
+  --only-retail
+
+

Make the script executable:

+
chmod a+x igir-romm-cleanup.sh
+
+

Usage

+

Run the script

+

Run the script. It will generate a new output directory named roms-verified, moving the files from roms-unverified if its checksum matches any of the known checksums in the DAT files provided. Any ROMs not identified will remain in the roms-unverified directory.

+

Manually move over remaining files

+

The script may not identify all of the ROMs in your input directory. You can choose to migrate them over manually:

+
npx -y igir@latest \
+  move \
+  -i roms-unverified/ \
+  -o roms-verified/ \
+  --dir-mirror
+
+

This will move your ROMs from the input to the output directory, preserving the subdirectory structure. It also cleans up file extensions in the process.

+

Reorganize multi-disc games

+

The Igir script will move games that have multiple discs to separate folders. This can confuse RomM's game detection, and those games need to be reorganized into single folders with many discs.

+

To do this enter your platform directory, such as ps or psx and run the following:

+
ls -d *Disc* | while read dir; do
+  game=$(echo "${dir}" | sed -r 's/ \(Disc [0-9]+\)//')
+  mkdir -p "${game}"
+  mv "${dir}"/* "${game}/"
+  rm -rf "${dir}"
+done
+
+

This will find any directory with (Disc in the name and move the files into a new directory without the (Disc #) string. For example:

+

Before:

+
Final Fantasy VII (Disc 1) (USA)
+Final Fantasy VII (Disc 2) (USA)
+
+

Gets combined to:

+
Final Fantasy VII (USA)
+

Authentication Issues

+ +

Error: 403 Forbidden

+

When authentication is enabled, most endpoints will return a 403 Forbidden response if you're not authenticated, or if your sessions is in a broken state. The session key can be reset by clearing your cookies.

+

CSRF protection is also enabled, which helps to mitigates CSRF attacks (useful if your instance is public). If you encounter a Forbidden (403) CSRF verification failed error, simply reloading your browser should force it to fetch a fresh CSRF cookie.

+

Error: Unable to login: CSRF token verification failed

+

This error is known to happen on Chrome, but could happen in other browsers; manually clear your cookies (specifically one called csrftoken) and hard reload your browser window (CMD+SHIFT+R on macOS, CTRL+F5 on Windows).

+

Error: 400 Bad Request on the Websocket endpoint

+

If you're running RomM behind a reverse-proxy (Caddy, Nginx, etc.), ensure that Websockets are supported and enabled. This may vary depending on the reverse proxy solution being used. In the case of Nginx Proxy Manager, enable the "Websockets Support" toggle when editing the proxy host.

Miscellaneous Issues

+ +

Restarting the container when using SQLite drops all the data/requires a full re-scan

+

Verify that the database is mapped to a persistent storage volume in your docker compose or Unraid template.

+
"/path/to/database:/romm/database" # [Optional] Only needed if ROMM_DB_DRIVER=sqlite or not set
+
+

Error: Could not get twitch auth token: check client_id and client_secret

+

This is likely due to mis-configured environment variables; verify that CLIENT_ID and CLIENT_SECRET are set correctly, and that both match the values in IGDB.

Scanning Issues

+ +

Scan is skipping all platforms/ends instantly

+

There are a few common reasons why a scan may end instantly/without scanning platforms

+
    +
  • Badly mounted library: verify that you mounted your ROMs folder at /romm/library
    • +
  • Incorrect permissions: the app needs to read the files and folders in your library, check their permissions with ls -lh
    • +
  • Invalid folder structure: verify that your folder structure matches the one in the README
    • +
+

ROMs not found for platform X, check romm folder structure

+

This is the same issue as the one above, and can be quickly solved by verifying your folder structure. RomM expects a library with a folder named roms in it, for example:

+
    +
  • /server/media/library:/romm/library
    • +
  • /server/media/games/roms:/romm/library/roms
    • +
+

Scan does not recognize a platform

+

When scanning the folders mounted in /library/roms, the scanner tries to match the folder name with the platform's slug in IGDB. If you notice that the scanner isn't detecting a platform, verify that the folder name matches the slug in the URL of the platform in IGDB. For example, the Nintendo 64DD has the URL https://www.igdb.com/platforms/nintendo-64dd, so the folder should be named nintendo-64dd.

+

Scan times out after ~4 hours

+

The background scan task times out after 4 hours, which can happen if you have a very large library. The easiest work around is to keep running scans every 4 hours, without checking the "Complete re-scan" option.

Synology Issues

+ +

ErrNo 13: Access Denied

+

We have noticed recently a spate of access denied on Synology systems via Portainer or even docker manager. The ErrNo13 is directly related to Synology and it is a simple permission issue. To fix it please do the following:

+
    +
  1. Make sure SSH is enabled on your Synology product. Refer to here if it is not Enable SSH
    2. +
  2. Connect to SSH and login as your admin username and password (Same login used to login to DSM web page)
    3. +
  3. Take a note on your user:group you can find this by typing ID when logged into SSH.
    4. +
  4. Type the following commands in the SSH window.
    5. +
+

sudo chown -R user:group /path/to/library

+

sudo chmod -R a=,a+rX,u+w,g+w /path/to/library

+

sudo chown -R user:group /path/to/assets

+

sudo chmod -R a=,a+rX,u+w,g+w /path/to/assets

+

sudo chown -R user:group /path/to/config

+

sudo chmod -R a=,a+rX,u+w,g+w /path/to/config

+

You will find the relevant directories in your compose, this is basically the folders where you store your RomM information and we are just resetting permissions. Restart the containers and you should now have no issues scanning information in!

+

Any issues please ask in the Discord.

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.

The `ReplaySubject` will also complete, if it has observed completion; and it will\n * error if it has observed an error.\n *\n * There are two main configuration items to be concerned with:\n *\n * 1. `bufferSize` - This will determine how many items are stored in the buffer, defaults to infinite.\n * 2. `windowTime` - The amount of time to hold a value in the buffer before removing it from the buffer.\n *\n * Both configurations may exist simultaneously.
