You find yourself locked out of closed source electron applications with no easy way to enable developer tools? β†· electron-inject is here to help πŸ‘²

Inject hotkeys F12:toggle devconsole and F5:reload into closed source apps with devconsole disabled.

--enable-devtools-hotkeys … enable developer hotkeys
--timeout=xx … patch all known remote webContent/windows in a timeframe of xx seconds. set this to an arbitrary high value to make sure we’re patching all future windows.

Render Scripts

Passing the -r file parameter allows to pass a list of scripts to be injected into the render thread. It does not follow imports, just evaluate the text

python -m electron_inject -r ./test.js -r ~/test2.js -r /usr/bin/test3.js - /opt/electron-api-demos/Electron\ API\ Demos
