I would like to debug my sails.js application but I don't know how to launch node-inspector for this occasion.

Normally it would go :

$ node --debug myapp.js

If I run my sails application normally :

$ sails lift --prod

and then launch node-inspector

$ node-inspector --debug-port 1337
Node Inspector v0.7.0-2
   info  - socket.io started
Visit http://127.0.0.1:8080/debug?port=1337 to start debugging.

I get this error in inspector GUI :

Error: read ECONNRESET. Check there is no other debugger client attached to port 1337.

As of Sails 0.9.8 you can use sailsd to call sails in debug mode, e.g. sailsd lift.

-- Edit --

Looks like this didn't actually make it into 0.9.8, my bad. To make your own debugging command for now, save the following into /usr/local/bin as sailsd (or whatever you like):

#!/bin/sh
node --debug `which sails` $@

-- Edit 2 --

In Sails v0.10.x, you can do sails debug instead of sails lift to start Sails in debug mode!

Correct me if im wrong but, you cant use debug port 1337 if sails lifts on port 1337.

try specifying a different port.

node --debug app.js
#this will lift sails on port 1337 and the default debug port i think its 5858
#start node-inspector, once it starts hit enter to put it into background
node-inspector &;
#visit http://127.0.0.1:8080/debug?port=5858

edit just confirmed this method works, instead of using sails lift you're using node to start app.js in debug mode. the node-inspector web runs on port 8080 and the debugger links on port 5858 by default.
