Thanks @gurbraj!

Thanks for a cool gem @justin808 ! Excited to try it out.

When I run the server with:

foreman start -f Procfile.dev

I can not connect to it from the client (my browser).

However, it works when I do the usual:
bin/rails s

I'm trying to integrate react onto an already made rails app.

Any ideas why? And can it become a problem down the line if I just use 'bin/rails s'?

Thanks!

@gurbraj

export PORT=3000

if you want to use localhost:3000

port 5000 is the default for foreman.
