An easy way to create a readable Stream
.
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.
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 also takes an Array
whose elements it emits one after another.
