how do i debug a node.js app using heroku foreman?

Question

i am new to heroku and node.js. i have a small node.js app which i can start and run successfully on my local machine using FOREMAN from the heroku toolbelt. i do not understand how to best debug the app, though.

i see that there is an eclipse debugger for node.js as well as the node-inspector project. but i cant seem to make these work with FOREMAN.

foreman start

if it is not possible to debug an app started by foreman, what is the purpose of foreman?

Answer 1

Just an addition, your Procfile could look like this:

web: node web.js
webDebug: node --debug-brk=5858 web.js`

So to start debugging you just call foreman start webDebug, you could call the configuration however you want.

The debugger will listen on port 5858 and you'll have to call your app from http://localhost:5100 instead of http://localhost:5000.
