Break up a stream and reassemble it so that each line is a chunk. matcher may be a `String`, or a `RegExp`
|
||
|
|
|
||
|
|
Example, read every line in a file ...
|
||
|
|
|
||
|
|
``` js
|
||
|
|
fs.createReadStream(file)
|
||
|
|
.pipe(split())
|
||
|
|
.on('data', function (line) {
|
||
|
|
//each chunk now is a seperate line!
|
||
|
|
})
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
`split` takes the same arguments as `string.split` except it defaults to '/\r?\n/' instead of ',', and the optional `limit` paremeter is ignored.

`split` accepts a function which transforms each line.
|
||
|
|
|
||
|
|
``` js
|
||
|
|
fs.createReadStream(file)
|
||
|
|
.pipe(split(JSON.parse))
|
||
|
|
.on('data', function (obj) {
|
||
|
|
//each chunk now is a a js object
|
||
|
|
})
|
||
|
|
.on('error', function (err) {
|
||
|
|
//syntax errors will land here
|
||
|
|
//note, this ends the stream.
|
||
|
|
})
|
||
|
|
```
