## Combine (stream1,...,streamN)
|
||
|
|
|
||
|
|
Turn a pipeline into a single stream. `Combine` returns a stream that writes to the first stream
|
||
|
|
and reads from the last stream.
|
||
|
|
|
||
|
|
Listening for 'error' will recieve errors from all streams inside the pipe.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var Combine = require('stream-combiner')
|
||
|
|
var es = require('event-stream')
|
||
|
|
|
||
|
|
Combine( // connect streams together with `pipe`
|
||
|
|
process.openStdin(), // open stdin
|
||
|
|
es.split(), // split stream to break on newlines
|
||
|
|
es.map(function (data, callback) { // turn this async function into a stream
|
||
|
|
var repr = util.inspect(JSON.parse(data)) // render it nicely
|
||
|
|
callback(null, repr)
|
||
|
|
}),
|
||
|
|
process.stdout // pipe it to stdout !
|
||
|
|
)
|
||
|
|
```
|
||
|
|
|
||
|
|
Can also be called with an array:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var combinedStream = Combine([
|
||
|
|
stream1,
|
||
|
|
stream2,
|
||
|
|
]);
|
||
|
|
```
|
||
|
|
|
||
|
|
Or to combine gulp plugins:
|
||
|
|
|
||
|
|
```js
|
||
|
|
function coffeePipe() {
|
||
|
|
return Combine(
|
||
|
|
coffeescript(),
|
||
|
|
coffeelint.reporter('fail').on('error', function(){
|
||
|
|
gutil.beep()
|
||
|
|
gulp.run('lint')
|
||
|
|
})
|
||
|
|
}
|
||
|
|
|
||
|
|
//usage:
|
||
|
|
gulp.src().pipe(coffeePipe());
|
||
|
|
```
