Changed: createFragment no longer includes nulls in its output (since toArray doesn't and they share code).
Changed: React.Children.map no longer warns for clashing keys; traverseAllChildren will later when rendering.
Also change the generated key format around to accomodate. My keys are probably not bulletproof but should definitely be safe against accidental collisions.
As discussed in issue 1326
(https://github.com/facebook/react/issues/1326) transitionend events are
unreliable; they may not fire because the element is no longer painted,
the browser tab is no longer focused or for a range of other reasons.
This is particularly harmful during leave transitions since the leaving
element will be permanently stuck in the DOM (and possibly visible).
The ReactCSSTransitionGroup now requires timeouts to be passed in
explicitly for each type of animation. Omitting the timeout duration
for a transition now triggers a PropTypes warning with a link to the
updated documentation.
This should contain all the rules we probably want to use, except
react/wrap-multilines, which requires a larger codemod, and would
clutter this commit.
See #2869
Checks that the *second* argument of warning and invariant are a literal
string, or a concatination of literal strings, and that the number of
arguments is correct based on the number of %s substrings.
This commit also fixes a few places where the existing code had broken
error messages!
The rule itself is pretty straightforward, although adding the tests
ended up being a bit painful, as eslint-tester depends on mocha, and
therefore needs to be run in a separate grunt task.
This is a machine-generated codemod, but it's pretty safe since it was
generated by hooking into eslint's own report.
A few files had to be touched up by hand because there were existing
formatting issues with nested arrays/objects:
src/shared/utils/__tests__/OrderedMap-test.js
src/shared/utils/__tests__/Transaction-test.js
src/shared/utils/__tests__/traverseAllChildren-test.js
src/isomorphic/children/__tests__/ReactChildren-test.js
Closes#3971.
> After #3968, the next thing we should do is start linting our tests.
> Historically we've ignored them due to lack of parser compatibility.
> But that shouldn't be a problem anymore. We may want to integrate
> https://www.npmjs.com/package/eslint-plugin-react to more aggressively
> lint our JSX in tests.
I understand this diff touches a lot of stuff, so I tried to keep it to
a near-minimal set of changes to make eslint happy.
- Removes esprima-fb dependency
- Tightens up eslintrc with some minor rules we were pretty-much
following anyways.
- Adds pretty colors to the `grunt lint` output
- Breaks block-scoped-var :(
This heuristic isn't great because it relies on inspecting deep children which aren't guaranteed to be React elements. In particular, this was causing stack overflows in a component we had that used a *DOM node* as children, like `<DOMContainer>{node}</DOMContainer>`.
This reverts commits:

The new folder structure is organized around major packages that are expected to ship separately in some form.
`/isomorphic`
I moved classic/modern and children utils into a directory called "isomorphic" with the main export being ReactIsomorphic. This will eventually become the "react" package.
This includes all the dependencies that you might need to create a component without dependencies on the renderer/reconciler.
The rest moves into decoupled renderers.
`/renderers/dom/client` - This is the main renderer for DOM.
`/renderers/dom/server` - This is the server-side renderer for HTML strings.
`/addons` and `/test` - Same as before for now.
You're not supposed to take on a dependency inside another package.
Shared code is organized into a "shared" directory which is intended to support all the packages in that subdirectory. Meaning that once we swap to CommonJS modules, the only time you should use `..` is to target `../shared/` or `../../shared`.
E.g. `/shared/` is common utils that are used by everything.
`/renderers/shared/` is code that is shared by all renderers, such as the main reconciliation algorithm.
Shared code will likely be copied into each package rather than referenced. This allow us to have separate state and allow inlining and deadcode elimination.
Also when reusing elements in multiple contexts -- before we were mutating each element to indicate its validity; now we mutate the array containing it (which we create, in the case of rest-arg children).
Fixes#2496. Fixes#3348.
