Descriptions

• Used version abc8ef3 of extension build

I am aware Electron is bit odd environment and probably experimental devtools have known glitches around, but couldn't figure out cause by myself and not successful to search existing issues.

Devtools simply doesn't work on Electron environment by throwing out Unsupported Bridge operation 0 - not sure 1. what does 0 actually means / 2. In what cases this could occur (Electron's devtools is nearly equivalent to Chromium devtools in most cases). Willing to dig deeper myself if I could have some clues or insights.

I can't reproduce the bug you've reported by running the example repo, but it looks like you copied part of this repo and tried to run it as an electron app. That's not supported. It actually requires a fair bit of work (see PR #335).

Once that PR has landed, a standalone version of v4 (running in Electron) will be available to support Safari and React Native. Actually, Safari support should mostly be there already if you'd like to check out the branch and build from source.

Until that feature lands though, the Electron shell is not supported by this version. 😄

@bvaughn I'm not sure if I understood correctly - isn't #335 tracking standalone usecase? Usecase repro I created is install crx into Electron's devtools as same as install crx in chromium's devtools. Current stable react devtools supports this cases - curious if #335 intends to resolve this.

Clarify, I am not trying to run current devtools as standalone.

Installing the extension into an unsupported browser (anything but Chrome, Firefox, and Chromium Edge) is also not supported. The extension APIs aren't guaranteed to be the same.
