I'm using the latest version (v6.0.0) of the wait-on npm package and my electron app didn't ever seem to pop up properly after my react app started up.

To investigate, I started up my react app on port 3000 and then cd'ed into my node_modules/wait-on/bin directory and ran ./wait-on tcp:3000 -v. I was getting the following error.

making TCP connection to 3000 ...
  error connecting to TCP host:localhost port:3000 Error: connect ECONNREFUSED ::1:3000
Enter fullscreen mode Exit fullscreen mode

My react app was 100% running on localhost:3000, as I could access it in my browser.

I stopped that running wait-on process and re-ran wait-on, passing my "localhost" IP into the wait-on command like so: ./wait-on tcp:127.0.0.1:3000 -v

Finally then got TCP connection successful to host:127.0.0.1 port:3000

So i modified the electron script in my package.json as follows:

    "electron": "wait-on tcp:127.0.0.1:3000 && electron .",
Enter fullscreen mode Exit fullscreen mode
