Builds on top of the existing Playwright tests to plug in the test selector API: https://gist.github.com/bvaughn/d3c8b8842faf2ac2439bb11773a19cec
My goals in doing this are to...
1. Experiment with the new API to see what works and what doesn't.
2. Add some test selector attributes (and remove DOM-structure based selectors).
3. Focus the tests on DevTools itself (rather than the test app).
I also took this opportunity to add a few new test cases– like named hooks, editable props, component search, and profiling- just to play around more with the Playwright API.
Relates to issue #22646
Adds the concept of subtree modes to DevTools to bridge protocol as follows:
1. Add-root messages get two new attributes: one specifying whether the root is running in strict mode and another specifying whether the root (really the root's renderer) supports the concept of strict mode.
2. A new backend message type (TREE_OPERATION_SET_SUBTREE_MODE). This type specifies a subtree root (id) and a mode (bitmask). For now, the only mode this message deals with is strict mode.
The DevTools frontend has been updated as well to highlight non-StrictMode compliant components.
The changes to the bridge protocol require incrementing the bridge protocol version number, which will also require updating the version of react-devtools-core backend that is shipped with React Native.
* import * as React from "react";
This is the correct way to import React from an ES module since the ES
module will not have a default export. Only named exports.
* import * as ReactDOM from "react-dom"
* Update Flow to 0.84
* Fix violations
* Use inexact object syntax in files from fbsource
* Fix warning extraction to use a modern parser
* Codemod inexact objects to new syntax
* Tighten types that can be exact
* Revert unintentional formatting changes from codemod
