Destroy a stream.
|
|
|
|
This module is meant to ensure a stream gets destroyed, handling different APIs
|
|
and Node.js bugs.
|
|
|
|
## API
|
|
|
|
```js
|
|
var destroy = require('destroy')
|
|
```
|
|
|
|
### destroy(stream)
|
|
|
|
Destroy the given stream. In most cases, this is identical to a simple
|
|
`stream.destroy()` call. The rules are as follows for a given stream:
|
|
|
|
1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
|
|
and add a listener to the `open` event to call `stream.close()` if it is
|
|
fired. This is for a Node.js bug that will leak a file descriptor if
|
|
`.destroy()` is called before `open`.
|
|
2. If the `stream` is not an instance of `Stream`, then nothing happens.
|
|
3. If the `stream` has a `.destroy()` method, then call it.
|
|
|
|
The function returns the `stream` passed in as the argument.
|
|
|
|
## Example
|
|
|
|
```js
|
|
var destroy = require('destroy')
|
|
|
|
var fs = require('fs')
|
|
var stream = fs.createReadStream('package.json')
|
|
|
|
// ... and later
|
|
destroy(stream)
|
|
```
