Difference between `npm start` & `node app.js`, when starting app?

From the man page, npm start:

runs a package’s “start” script, if one was provided.
If no version is specified, then it starts the “active” version.

Admittedly, that description is completely unhelpful, and that’s all it says. At least it’s more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

“scripts”: { “start”: “coffee server.coffee” }

then it will do that. If npm can’t find your start script, it defaults to:

node server.js
