## Summary
- #26234 is reverted and replaced with a better approach
- introduce a new global devtools variable to decouple the global hook's
dependency on backend/console.js, and add it to react-devtools-inline
and react-devtools-standalone
With this PR, I want to introduce a new principle to hook.js: we should
always be alert when editing this file and avoid importing from other
files.
In the past, we try to inline a lot of the implementation because we use
`.toString()` to inject this function from the extension (we still have
some old comments left). Although it is no longer inlined that way, it
has became now more important to keep it clean as it is a de facto
global API people are using (9.9K files contains it on Github search as
of today).
**File size change for extension:**
Before:
379K installHook.js
After:
21K installHook.js
363K renderer.js
## Summary
When looking into the compiled code of `installHook.js` of the extension
build, I noticed that it actually includes the large `attach` function
(from renderer.js). I don't think it was expected.
This is because `hook.js` imports from `backend/console.js` which
imports from `backend/renderer.js` for `getInternalReactConstants`
A straightforward way is to extract function
`getInternalReactConstants`. However, I think it's more simplified to
just merge these two files and save the 361K renderer.js from the
extension build since we have always been loading this code anyways.
I changed the execution check from `__REACT_DEVTOOLS_ATTACH__ ` to the
session storage.
## How did you test this change?
Everything works normal in my local build.
## Summary
resolves#24522
To upgrade to Manifest V3, one of the biggest issue is that we are no
longer allowed to add a script element with code in textContent so that
it would run synchronously. It's necessary for us because we need to
inject a global hook for react reconciler to detect whether devtools
exist.
To do that, we'll leverage a new API
`chrome.scripting.registerContentScripts` in V3. Particularly, we rely
on the "world" option (added in Chrome v102
[commit](https://chromium.googlesource.com/chromium/src/+/e5ad3451c17b21341b0b9019b074801c44c92c9f))
to run it in the "main world" on the page.
This PR also renames a few content script files so that it's easier to
tell them apart from other extension scripts and understand the purpose
of each of them.
Manifest V3 is not yet ready for Firefox, so we need to keep some code
for compatibility.
