SSH into a Vagrant VM, such that Node.js can be debugged from a debugger or IDE in the host operating system. For some reason, port forwarding in the Vagrant file does not work. See https://groups.google.com/forum/#!topic/vagrant-up/RzPooJ0dp6Q

# SSH into a Vagrant VM, forwarding ports in a way that allows node within Vagrant to be debugged by a debugger

/usr/bin/vagrant ssh-config > $TMPDIR/vagrant-ssh-config
ssh -F $TMPDIR/vagrant-ssh-config -L 5858:127.0.0.1:5858 default
rm $TMPDIR/vagrant-ssh-config

Thanks a lot, I am a newbie to nodejs, and this saved my week !

Try this:

Vagrantfile:

config.vm.network :forwarded_port, host: 5858, guest: 5858
config.vm.network :forwarded_port, host: 8080, guest: 8080

SSH to Vagrant

$ vagrant ssh
$ cd /vagrant/....
$ node-inspector &
$ node --debug app.js

Access using:

http://127.0.0.1:8080/?ws=127.0.0.1:8080&port=5858

Works Fine!!

I update this to take an argument as an arbitrary port, https://gist.github.com/drewsonne/747b1ce77cc2f912af0f

By default node-debug will bind to 127.0.0.1 which is loopback.

Use node-debug --web-host=0.0.0.0 to bind it to all interfaces. Forwarding port 8080 should now work.
