Node.js Question

Heroku failing to start my node app because its trying to do it with nodemon

I'm deploying my node app to Heroku and it's trying to invoke it with nodemon rather than the

node app.js
I have defined. My Procfile looks like this:

web: npm start


And when I push to heroku the dyno crashes with this error:

2014-03-24T19:24:59.669412+00:00 app[web.1]: > my-app@0.0.1 start /app
2014-03-24T19:24:59.669412+00:00 app[web.1]: > nodemon app.js
2014-03-24T19:24:59.669412+00:00 app[web.1]:
2014-03-24T19:24:59.669412+00:00 app[web.1]:
2014-03-24T19:24:59.710228+00:00 app[web.1]:
2014-03-24T19:24:59.701246+00:00 app[web.1]: sh: nodemon: not found


I even tried npm installing nodemon as a package.json dependency, and checking in node_modules/nodemon but no luck. (nodemon needs to be installed with
npm install nodemon -g
for that to work anyway)

Any ideas?

My package.json:

Update

Sorry to have left everyone hanging all this time! If I remember correctly my issue in the end was my buildpack which was overriding the web: role in my Procfile.

I've since switched to different buildpacks, namely:
ddollar/heroku-buildpack-multi

With the following .buildpacks file:

ryandotsmith/nginx-buildpack
heroku/heroku-buildpack-nodejs


And my Procfile looks like this:

web: bin/start-nginx ./node_modules/.bin/forever --minUptime 10000 --spinSleepTime 1000 app.js

Answer

Change your Procfile to this:

web: node app.js

Being app.js the entry point to your app.

This is assuming you don't really need nodemon in your app, since you have listed it at the package.json sample you provided.
