NAME

np-start- Start a package  

Synopsis

npm start [lB- <args>[rB]

 

Description

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 [rs]fBnpm@2.0.0[rs]fR lahttps://blog.npmjs.org/post/98131109725/np---0ra, you can use custom arguments when executing scripts. Refer to npm help run for more details.  

Example

{
  "scripts": {
    "start": "node foo.js"
  }
}

npm start

> npm@x.x.x start
> node foo.js

(foo.js output would be here)

 

Configuration

 

ignor-scripts

*

Default: false

*

Type: Boolean

If true, npm does not run scripts specified in package.json files. Note that commands explicitly intended to run a particular script, such as npm start, npm stop, npm restart, npm test, and npm run will still run their intended script if ignor-scripts is set, but they will not run any pr- or pos-scripts.  

scrip-shell

*

Default: '/bin/sh' on POSIX systems, 'cmd.exe' on Windows

*

Type: null or String

The shell to use for scripts run with the npm exec, npm run and npm init <packag-spec> commands.
