## Quick Example
|
||
|
|
|
||
|
|
### End stream once a fixed length has been reached
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var SliceStream = require('../');
|
||
|
|
var streamBuffers = require("stream-buffers");
|
||
|
|
|
||
|
|
var ss = new SliceStream({ length: 5}, function (buf, sliceEnd, extra) {
|
||
|
|
if (!sliceEnd) {
|
||
|
|
return this.push(buf);
|
||
|
|
}
|
||
|
|
this.push(buf);
|
||
|
|
return this.push(null); //signal end of data
|
||
|
|
});
|
||
|
|
|
||
|
|
var sourceStream = new streamBuffers.ReadableStreamBuffer();
|
||
|
|
sourceStream.put("Hello World");
|
||
|
|
var writableStream = new streamBuffers.WritableStreamBuffer();
|
||
|
|
|
||
|
|
sourceStream
|
||
|
|
.pipe(ss)
|
||
|
|
.pipe(writableStream)
|
||
|
|
.once('close', function () {
|
||
|
|
var str = writableStream.getContentsAsString('utf8');
|
||
|
|
console.log('First 5 bytes piped:', "'" + str + "'");
|
||
|
|
sourceStream.destroy();
|
||
|
|
});
|
||
|
|
|
||
|
|
//Output
|
||
|
|
//Piped data before pattern occurs: 'Hello'
