|
|
A cross platform solution to node's spawn and spawnSync.
|
||
|
|
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
`$ npm install cross-spawn`
|
||
|
|
|
||
|
|
If you are using `spawnSync` on node 0.10 or older, you will also need to install `spawn-sync`:
|
||
|
|
|
||
|
|
`$ npm install spawn-sync`
|
||
|
|
|
||
|
|
|
||
|
|
## Why
|
||
|
|
|
||
|
|
Node has issues when using spawn on Windows:
|
||
|
|
|
||
|
|
- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
|
||
|
|
- It does not support [shebangs](http://pt.wikipedia.org/wiki/Shebang)
|
||
|
|
- It does not allow you to run `del` or `dir`
|
||
|
|
- It does not properly escape arguments with spaces or special characters
|
||
|
|
|
||
|
|
All these issues are handled correctly by `cross-spawn`.
|
||
|
|
There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var spawn = require('cross-spawn');
|
||
|
|
|
||
|
|
// Spawn NPM asynchronously
|
||
|
|
var child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
|
||
|
|
|
||
|
|
// Spawn NPM synchronously
|
||
|
|
var results = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Tests
|
||
|
|
|
||
|
|
`$ npm test`
