# from

|
|
|

|
|
An easy way to create a `readable Stream`.
|
||
|
|
|
||
|
|
## from(function getChunk(count, next))
|
||
|
|
|
||
|
|
from takes a `getChunk` function and returns a stream.
|
||
|
|
|
||
|
|
`getChunk` is called again and again, after each time the user calls `next()`,
|
||
|
|
until the user emits `'end'`
|
||
|
|
|
||
|
|
if `pause()` is called, the `getChunk` won't be called again untill `resume()` is called.
|
||
|
|
|
||
|
|
|
||
|
|
```js
|
||
|
|
var from = require('from')
|
||
|
|
|
||
|
|
var stream =
|
||
|
|
from(function getChunk(count, next) {
|
||
|
|
//do some sort of data
|
||
|
|
this.emit('data', whatever)
|
||
|
|
|
||
|
|
if(itsOver)
|
||
|
|
this.emit('end')
|
||
|
|
|
||
|
|
//ready to handle the next chunk
|
||
|
|
next()
|
||
|
|
//or, if it's sync:
|
||
|
|
return true
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
## from(array)
|
||
|
|
|
||
|
|
from also takes an `Array` whose elements it emits one after another.
