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 [, suppress]) |
|
|
|
Destroy the given stream, and optionally suppress any future `error` events. |
|
|
|
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 an instance of a zlib stream, then call `stream.destroy()` |
|
and close the underlying zlib handle if open, otherwise call `stream.close()`. |
|
This is for consistency across Node.js versions and a Node.js bug that will |
|
leak a native zlib handle. |
|
3. If the `stream` is not an instance of `Stream`, then nothing happens. |
|
4. 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) |
|
``` |
