I'm learning to work with node and express, I used express generator to setup a basic project and I pushed it to heroku, but I got this error in logs:

2015-12-27T16:29:04.392014+00:00 heroku[web.1]: State changed from starting to crashed
It started working when I changed this
"scripts": {
"start": "nodejs ./bin/www"
},
to this
"scripts": {
"start": "node ./bin/www"
},
but I don't know why, can anyone explain the difference between node and nodejs, and how this works with heroku.
Thx
Express generator creates a startup script that runs the command node ./bin/www
which starts up your Express app by running the .bin/www
JavaScript file. The problem was that there is/was no command labled nodejs
, but there is one called node
(which points to the node.js executable).
Nodejs (node.js) is often called just node
for short, typically so for command prompts.
