* Set 'size' attribute to select tag if it occurs before appending options
* Add comment about why size is assigned on select create. Tests
I added some more clarification for why size must be set on select
element creation:
- In the source code
- In the DOM test fixture
- In a unit test
* Use let, not const in select tag stub assignment
* Hydration Fixture: Only load ReactDOMServer if it exists
Fixes an issue where the hydration fixture would try to load in
ReactDOMServer below version 14. In version 13, string markup methods
exist on the React namespace.
* DOM Fixtures: Use class component for App.js
This was breaking React 0.13.0.
* Hydration Fixture: better findDOMNode compatibility
This commit fixes an issue where the Hydration DOM fixture was
unusable in React 0.13.0 or lower because of newer API usage.
It fixes that by avoiding the use of refs to get the textarea
reference in the code editor component, using various versions of
findDOMNode as required.
* Hydration Fixture: Do not show dropdown for single-line errors
If an error showed for the hydration fixture, a detail element was
used even if no additional lines could display. In that case, this
commit changes the component such that it returns a div.
* Deeper React version support for hydration fixture
This commit adds support for versions 0.4.0 of React and higher for
the hydration fixture.
The DOM test fixtures themselves do not support down to React 0.4.0,
which would be exhaustive. Instead, the Hydration fixture can pick a
version to use for its own purposes. By default, this is the version
of React used by the fixtures.
In the process of doing this, I had to make some updates to the
renderer.html document associated with the hydration fixture, and I've
added some comments to better document the history of API changes.
* Add ESLint rule for useEffect/useCallback/useMemo Hook dependencies
* Fix ReactiveDependencies rule
* fix lint errors
* Support useLayoutEffect
* Add some failing tests and comments
* Gather dependencies in child scopes too
* If we don't find foo.bar.baz in deps, try foo.bar, then foo
* foo is enough for both foo.bar and foo.baz
* Shorter rule name
* Add fixable meta
* Remove a bunch of code and start from scratch
* [WIP] Only report errors from dependency array
This results in nicer editing experience. Also has autofix.
* Fix typo
* [Temp] Skip all tests
* Fix the first test
* Revamp the test suite
* Fix [foo] to include foo.bar
* Don't suggest call expressions
* Special case 'current' for refs
* Don't complain about known static deps
* Support useImperativeHandle
* Better punctuation and formatting
* More uniform message format
* Treat React.useRef/useState/useReducer as static too
* Add special message for ref.current
* Add a TODO case
* Alphabetize the autofix
* Only alphabetize if it already was
* Don't add static deps by default
* Add an undefined variable case
* Tweak wording
* Rename to exhaustive-deps
* Clean up / refactor a little bit
* Basic partial hydration test
* Render comments around Suspense components
We need this to be able to identify how far to skip ahead if we're not
going to hydrate this subtree yet.
* Add DehydratedSuspenseComponent type of work
Will be used for Suspense boundaries that are left with their server
rendered content intact.
* Add comment node as hydratable instance type as placeholder for suspense
* Skip past nodes within the Suspense boundary
This lets us continue hydrating sibling nodes.
* A dehydrated suspense boundary comment should be considered a sibling
* Retry hydrating at offscreen pri or after ping if suspended
* Enter hydration state when retrying dehydrated suspense boundary
* Delete all children within a dehydrated suspense boundary when it's deleted
* Delete server rendered content when props change before hydration completes
* Make test internal
* Wrap in act
* Change SSR Fixture to use Partial Hydration
This requires the enableSuspenseServerRenderer flag to be manually enabled
for the build to work.
* Changes to any parent Context forces clearing dehydrated content
We mark dehydrated boundaries as having child work, since they might have
components that read from the changed context.
We check this in beginWork and if it does we treat it as if the input
has changed (same as if props changes).
* Wrap in feature flag
* Treat Suspense boundaries without fallbacks as if not-boundaries
These don't come into play for purposes of hydration.
* Fix clearing of nested suspense boundaries
* ping -> retry

* Use didReceiveUpdate instead of manually comparing props
* Leave comment for why it's ok to ignore the timeout
* [Fizz] Add Flow/Jest/Rollup build infra
Add a new package for react-stream which allows for custom server renderer
outputs. I picked the name because it's a reasonable name but also
because the npm name is currently owned by a friend of the project.
The react-dom build has its own inlined server renderer under the
name `react-dom/fizz`.
There is also a noop renderer to be used for testing. At some point
we might add a public one to test-renderer but for now I don't want to have
to think about public API design for the tests.
* Add FormatConfig too
We need to separate the format (DOM, React Native, etc) from the host
running the server (Node, Browser, etc).
* Basic wiring between Node, Noop and DOM configs
The Node DOM API is pipeToNodeStream which accepts a writable stream.
* Merge host and format config in dynamic react-stream entry point
Simpler API this way but also avoids having to fork the wrapper config.
Fixes noop builds.
* Add setImmediate/Buffer globals to lint config
Used by the server renderer
* Properly include fizz.node.js
Also use forwarding to it from fizz.js in builds so that tests covers
this.
* Make react-stream private since we're not ready to publish
or even name it yet
* Rename Renderer -> Streamer
* Prefix react-dom/fizz with react-dom/unstable-fizz
* Add Fizz Browser host config
This lets Fizz render to WHATWG streams. E.g. for rendering in a
Service Worker.
I added react-dom/unstable-fizz.browser as the entry point for this.
Since we now have two configurations of DOM. I had to add another
inlinedHostConfigs configuration called `dom-browser`. The reconciler
treats this configuration the same as `dom`. For stream it checks
against the ReactFizzHostConfigBrowser instead of the Node one.
* Add Fizz Browser Fixture
This is for testing server rendering - on the client.
* Lower version number to detach it from react-reconciler version
* Add a checkbox to fixtures UI to choose React production build
* Assign header__label class name to label directly, instead of using a separate span
* center the production checkbox vertically
We are using it with lazy and the combination Suspense + lazy seems pretty
stable. maxDuration is not but that's only enabled when you're in
ConcurrentMode which is still unstable.
* Store the start time on `updateQueue` instead of `stateNode`
Originally I did this to free the `stateNode` field to store a second
set of children. I don't we'll need this anymore, since we use fragment
fibers instead. But I still think using `updateQueue` makes more sense
so I'll leave this in.
* Use fragment fibers to keep the primary and fallback children separate
If the children timeout, we switch to showing the fallback children in
place of the "primary" children. However, we don't want to delete the
primary children because then their state will be lost (both the React
state and the host state, e.g. uncontrolled form inputs). Instead we
keep them mounted and hide them. Both the fallback children AND the
primary children are rendered at the same time. Once the primary
children are un-suspended, we can delete the fallback children — don't
need to preserve their state.
The two sets of children are siblings in the host environment, but
semantically, for purposes of reconciliation, they are two separate
sets. So we store them using two fragment fibers.
However, we want to avoid allocating extra fibers for every placeholder.
They're only necessary when the children time out, because that's the
only time when both sets are mounted.
So, the extra fragment fibers are only used if the children time out.
Otherwise, we render the primary children directly. This requires some
custom reconciliation logic to preserve the state of the primary
children. It's essentially a very basic form of re-parenting.
* Use `memoizedState` to store various pieces of SuspenseComponent's state
SuspenseComponent has three pieces of state:
- alreadyCaptured: Whether a component in the child subtree already
suspended. If true, subsequent suspends should bubble up to the
next boundary.
- didTimeout: Whether the boundary renders the primary or fallback
children. This is separate from `alreadyCaptured` because outside of
strict mode, when a boundary times out, the first commit renders the
primary children in an incomplete state, then performs a second commit
to switch the fallback. In that first commit, `alreadyCaptured` is
false and `didTimeout` is true.
- timedOutAt: The time at which the boundary timed out. This is separate
from `didTimeout` because it's not set unless the boundary
actually commits.
These were previously spread across several fields.
This happens to make the non-strict case a bit less hacky; the logic for
that special case is now mostly localized to the UnwindWork module.
* Hide timed-out Suspense children
When a subtree takes too long to load, we swap its contents out for
a fallback to unblock the rest of the tree. Because we don't want
to lose the state of the timed out view, we shouldn't actually delete
the nodes from the tree. Instead, we'll keep them mounted and hide
them visually. When the subtree is unblocked, we un-hide it, having
preserved the existing state.
Adds additional host config methods. For mutation mode:
- hideInstance
- hideTextInstance
- unhideInstance
- unhideTextInstance
For persistent mode:
- cloneHiddenInstance
- cloneUnhiddenInstance
- createHiddenTextInstance
I've only implemented the new methods in the noop and test renderers.
I'll implement them in the other renderers in subsequent commits.
* Include `hidden` prop in noop renderer's output
This will be used in subsequent commits to test that timed-out children
are properly hidden.
Also adds getChildrenAsJSX() method as an alternative to using
getChildren(). (Ideally all our tests would use test renderer #oneday.)
* Implement hide/unhide host config methods for DOM renderer
For DOM nodes, we hide using `el.style.display = 'none'`.
Text nodes don't have style, so we hide using `text.textContent = ''`.
* Implement hide/unhide host config methods for Art renderer
* Create DOM fixture that tests state preservation of timed out content
* Account for class components that suspend outside concurrent mode
Need to distinguish mount from update. An unfortunate edge case :(
* Fork appendAllChildren between persistent and mutation mode
* Remove redundant check for existence of el.style
* Schedule placement effect on indeterminate components
In non-concurrent mode, indeterminate fibers may commit in an
inconsistent state. But when they update, we should throw out the
old fiber and start fresh. Which means the new fiber needs a
placement effect.
* Pass null instead of current everywhere in mountIndeterminateComponent
All of these features are based on features of React's internal
scheduler. The eventual goal is to lift as much as possible out of the
React internals into the Scheduler package.
Includes some renaming of existing methods.
- `scheduleWork` is now `scheduleCallback`
- `cancelScheduledWork` is now `cancelCallback`
Priority levels
---------------
Adds the ability to schedule callbacks at different priority levels.
The current levels are (final names TBD):
- Immediate priority. Fires at the end of the outermost currently
executing (similar to a microtask).
- Interactive priority. Fires within a few hundred milliseconds. This
should only be used to provide quick feedback to the user as a result
of an interaction.
- Normal priority. This is the default. Fires within several seconds.
- "Maybe" priority. Only fires if there's nothing else to do. Used for
prerendering or warming a cache.
The priority is changed using `runWithPriority`:
```js
runWithPriority(InteractivePriority, () => {
scheduleCallback(callback);
});
```
Continuations
-------------
Adds the ability for a callback to yield without losing its place
in the queue, by returning a continuation. The continuation will have
the same expiration as the callback that yielded.
Wrapped callbacks
-----------------
Adds the ability to wrap a callback so that, when it is called, it
receives the priority of the current execution context.
* Add home component. Async load fixtures.
This commit adds a homepage to the DOM fixtures that includes browser
testing information and asynchronously loads fixtures.
This should make it easier to find DOM testing information and keep
the payload size in check as we add more components to the fixtures.
* Adds experimental hydration fixture
This commit adds a first pass at a fixture that makes it easier to
debug the process of hydrating static markup. This is not complete:
1. It needs to be verified across multiple browsers
2. It needs to render with the current version of react
Still, it at least demonstrates the idea. A fixture like this will
also be helpful for debugging change events for hydrated inputs, which
presently do not fire if the user changes an input's text before
hydration.
* Tweak select width
* Manually join extra attributes in warning
This prevents a bug where Chrome reports `Array(n)` where `n` is the
size of the array.
* Transform with buble
* Eliminate dependencies
* Pull in react-live for better editing
* Handle encoding errors, pass react version
* Load the correct version of React
* Tweaks
* Revert style change
* Revert warning update
* Properly handle script errors. Fix dom-server CDN loading
* Fix 15.x releases
* Use postMessage to reduce latency, support older browsers
This commit makes a few tweaks to support older browsers and updates
the code transition process to use window.postMessage. This avoids
loading React on every single change.
* Fix fixture renamespacing bug
* Gracefully fallback to textarea in React 14
* Replace buble with babel, react-live with codemirror
* Simplify layout to resolve production code-mirror issues
* Tweak height rules for code-mirror

* Make code example more concise
* Replace "Hydrate" with "Auto-hydrate" for clarity
* Remove border below hydration header
* Rename query function in render.js
* Use Function(code) to evaluate hydration fixture
For clarity, and so that the Fixture component does not need to be
assigned to the window, this commit changes the way code is executed
such that it evaluates using a Function constructor.
* Extend hydration fixture to fill width. Design adjustments
This commit extends the hydration fixture such that it takes up the
full screen view. To accomplish this, the container that wraps all
fixtures has been moved to the FixtureSet component, utilized by all
other fixtures.
* Improve error scroll state
* Lazy load CodeMirror together before executing
This commit fixes an issue where CodeMirror wouldn't layout correctly
in production builds because the editor executes before the stylesheet
loaded. CodeMirror needs layout information, and was rendering
off-screen without correct CSS layout measurements.
* Fix indentation on error message
* Do not highlight errors from Babel. Add setPrototypeOf polyfill
This commit fixes an error in Safari 7.1 where Chalk highlighted Babel
errors caused a crash when setPrototypeOf was called within the
library.
This is also an issue on IE9, however this fix does not resolve issues
in that browser.
* Increase resilience to bad errors in Hydration fixture
- Reverts highlighting change. Polyfilling Safari 7.1 is sufficient
- Do not render a details tag in IE9
* Removed 'private' ref methods from UMD forwarding API
