Start a package


npm start [-- <args>]


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)
