REACT_DEVELOPER_TOOLS is not loading

[yougotwill]

Hi thanks for making this great package!

I have tested REACT_DEVELOPER_TOOLS and fmkadmapgofadopljbjfkapdkoienihi and the extension does not load in the Chrome Dev Tools Inspector. REDUX_DEVTOOLS does work so the package is working correctly.

Hello, I just tested it. After electron started, Chrome Developer Tools did not load the react extension. But after Ctrl+R refreshed the page, the react extension was loaded.
Try it.

It seems that my REACT_DEVELOPER_TOOLS aren't installing. Please help.

[tomgao365]

@Imaginativeone Hello, please try to use the electron API to load the extension directly to see if there is any problem.
Replace

installExtension(REACT_DEVELOPER_TOOLS) // equals to installExtension("nhdogjmejiglipccpnnnanhbledajbpd")
      .then(ext => console.log(`Added Extension:  ${ext.name}`))
      .catch(err => console.log('An error occurred: ', err));
    })

To

 import { session} from 'electron';
   session.defaultSession
      .loadExtension(
        `C:\\Users\\dfranklin\\AppData\\Roaming\\Electron\\extensions\\fmkadmapgofadopljbjfkapdkoienihi`,

You should import session

 import { session} from 'electron';

This plugin just downloads the corresponding extension before calling the session.defaultSession.loadExtension method. Check your computer

1. Check if the extension is downloaded successfully, for example, check if the path C:\Users\dfranklin\AppData\Roaming\Electron\extensions\fmkadmapgofadopljbjfkapdkoienihi is decompressed normally
2. Check if session.defaultSession.loadExtension is successful
3. Refresh the page and check if React Develop Tools is loaded

Aaahh...it's not loading new stuff there. Gotta figure out why not.

Are you open to posting a working demo app?

[Imaginativeone]

Never mind...found it.
