[DevTools] browser extension: improve script injection logic #26492

mondaychen · 2023-03-27T21:49:31Z

Summary

Drop extension support for Chrome / Edge <v102 since they have less than 0.1% usage (see data)
Improve script injection logic when possible so that the scripts injected by the extension are no longer shown in Network (which caused a lot of confusion in the past)

How did you test this change?

Built and tested locally, works as usual on Firefox.

For Chrome/Edge

Before:
Scripts shown in Network tab

After:
No scripts shown

nit: Should we put react-devtools-inject-backend into constant?

I see its used in multiple places:

react/packages/react-devtools-extensions/src/main.js

Line 192 in 41b4714

`window.postMessage({ source: 'react-devtools-inject-backend' }, '*');`,

react/packages/react-devtools-extensions/src/contentScripts/prepareInjection.js

Line 92 in 41b4714

case 'react-devtools-inject-backend':

Many event names/types are used in this way. I'm not against extracting them into a shared constant file as a better engineering work, but let's use another PR to take care of them all together.

The big difference imo between using a constant and literals in that a constant will get allocated at the module level and would weight the sum of all the literals plus some small management extra.
Literals on the other hand are only allocated when used and referenced (they may even get GCed like in case constant).

Is xor operator expected here?

Thanks for catching this!

Is it XOR operator? I think ^ is XOR operator.

Yeah, my bad, its a bitwise or

…docked devtools window (#26665) bugfix for #26492 This bug would cause users unable to use the devtools (component tree empty).
