Frequently Asked Questions

Where are Babel, ESLint and stylelint configured?

In package.json

Where are the files coming from when I run $ npm start?

In development Webpack compiles your application runs it in-memory. Only when you run $ npm run build will it write to disk and preserve your bundled application across computer restarts.

How do I fix Error: listen EADDRINUSE 127.0.0.1:3000?

This simply means that there's another process already listening on port 3000. The fix is to kill the process and rerun npm start.

OS X:

1. Find the process id (PID):

   $ ps aux | grep node

   This will return the PID as the value following your username:

   $ janedoe    29811  49.1  2.1  3394936 356956 s004  S+    4:45pm   2:40.07 node server

2. Then run

   $ kill -9 YOUR_PID

   e.g. given the output from the example above, YOUR_PID is 29811, hence that would mean you would run kill -9 29811

Windows

1. Find the process id (PID):

   C:\> netstat -a -o -n

   This will return a list of running processes and the ports they're listening on:

   Proto     Local Address     Foreign Address   State       PID
   TCP       0.0.0.0:25        0.0.0.0:0         Listening   4196
   ...
   TCP       0.0.0.0:3000      0.0.0.0:0         Listening   28344
   

2. Then run

   C:\> taskkill /F /PID YOUR_PID

   e.g. given the output from the example above, YOUR_PID is 28344, hence that would mean you would run taskkill /F /PID 28344
