Express not listening on localhost:3000

Question

So, we've built a basic express node website

Trying to run the app with DEBUG=express_example:* npm start

With node DEBUG=express_example:* npm start

Also, tried inside node runtime:

http://localhost:3000/ is not connecting

Where are we wrong?

It's most likely the app.js file, need to see how express is being served and initialized. — Pogrindis

I see, just to test github.com/shapeshed/express_example/blob/master/bin/www#L15 change this port var to = 3000; only.. and try again — Pogrindis

You need to create a variable called DEBUG with set command. There is not command like DEBUG, it is a name of variable, so please try to run your server with set (to create variable):

set DEBUG=express_example:* & npm start

@KrzysztofBargieł Yes, it worked!!! Thanks brotha! Can you educate me on what made you decide that DEBUG is not a command and it needs to be set.

Try

DEBUG='express_example:*' npm start

Your environment variable was not getting set properly. Note that you can have many different environment variables this way

TEST=foo DEBUG='bar' npm start
