This runs a predefined command specified in the "start" property of
a package's "scripts" object.
If the "scripts" object does not define a "start" property, npm
will run node server.js.
Note that this is different from the default node behavior of running
the file specified in a package's "main" attribute when evoking with
node .
As of npm@2.0.0, you can
use custom arguments when executing scripts. Refer to npm run-script for more details.
{
"scripts": {
"start": "node foo.js"
}
}
npm start > npm@x.x.x start > node foo.js (foo.js output would be here)
