Eugene ChoiandGitHub f7254efc5c [playground] Persist open tabs on compiler error (#34673)
This change allows it so that tabs that were open before a compiler
error are automatically opened again when the error is resolved. Quality
of life change for those especially working with the advanced view of
the playground.

React Compiler Playground

An interactive playground to demonstrate, test, and have fun with React Compiler.

Setup

# Build React Compiler from source and install Playground dependencies.
$ yarn

# Or similarly
$ npm install

Development

# Start the local development server with
$ yarn dev

# Or
$ npm run dev

# Rerun the following (in a separate terminal window) when React Compiler
# is changed locally to keep Playground in sync.
$ yarn

Testing

# Install playwright browser binaries
$ npx playwright install --with-deps
# Run tests
$ yarn test

Deployment

This project has been deployed using Vercel. Vercel does the exact same thing as we would locally, by running yarn at the install step in the Playground directory to build React Compiler from source and symlink it as its dependency. This means that Playground is automatically deployed on every push and pull requests will reflect the behaviors of React Compiler of that commit.
