node.js - How to start the Cloud9 debugger with MeanJS -

newbie warning...

i followed tutorial (from freecodecamp) setup new mean.js stack in cloud9. https://vimeo.com/123488494

the tutorial says start application running command:

npm start 

which works fine... except debugger doesn't attach , can't use breakpoints, etc.

what magic missing?

figured out on own, sort of (no, didn't take 2 days). here's detailed "whats up" future newbies stumble on this...

the tutorial said start app npm command:

npm start 

for reason not yet clear me, npm calls "start script" specified in package.json @ path... /scripts/start (and other stuff... read manual).

the default install had in scripts section:

   "scripts": {       "start": "grunt",       "test": "grunt test",       "postinstall": "bower install --config.interactive=false"    }, 

so...

npm start 

is fancy way of running...

grunt 

grunt "javascript task runner", looks runs javascript in gruntfile.js - populated default install.

gruntfile.js has entry:

nodemon: {     dev: {         script: 'server.js',         options: {             nodeargs: ['--debug'],             ext: 'js,html',             watch: watchfiles.serverviews.concat(watchfiles.serverjs)         }     } }, 

at point, grunt firing off node server startup command evidenced output message:

[nodemon] starting `node --debug server.js` 

... cloud9 not respecting --debug request reason... many fancy indirections or something.

so did create new cloud9 run configuration (run (menu) > run configurations > new run configuration):

name: debug command: server   <<<  executes server.js runner: node.js 

then can use debug. seem working ok, few minutes @ point. there seem bunch of stuff skipped starting app way... debugger sure come in handy. i'll try use when want debug.

i love learning new technologies... wish faster.

b.t.w. if has better solution or more experienced perspective on this, i'd happy mark response answer!

another nice side effect of alternate run approach takes way less memory run!!!! no longer warning messages asking me upgrade precious cloud 9 free account.
