title: npm-start
|
|
section: 1
|
|
description: Start a package
|
|
---
|
|
|
|
### Synopsis
|
|
|
|
```bash
|
|
npm start [-- <args>]
|
|
```
|
|
|
|
### 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 [`npm@2.0.0`](https://blog.npmjs.org/post/98131109725/npm-2-0-0), you can
|
|
use custom arguments when executing scripts. Refer to [`npm run-script`](/commands/npm-run-script) for more details.
|
|
|
|
### Example
|
|
|
|
```json
|
|
{
|
|
"scripts": {
|
|
"start": "node foo.js"
|
|
}
|
|
}
|
|
```
|
|
|
|
```bash
|
|
npm start
|
|
|
|
> npm@x.x.x start
|
|
> node foo.js
|
|
|
|
(foo.js output would be here)
|
|
|
|
```
|
|
|
|
### Configuration
|
|
|
|
#### `ignore-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-script`
|
|
will still run their intended script if `ignore-scripts` is set, but they
|
|
will *not* run any pre- or post-scripts.
|
|
|
|
#### `script-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 <package-spec>` commands.
