## Usage
|
||
|
|
|
||
|
|
``` js
|
||
|
|
var each = require('stream-each')
|
||
|
|
|
||
|
|
each(stream, function (data, next) {
|
||
|
|
console.log('data from stream', data)
|
||
|
|
// when ready to consume next chunk
|
||
|
|
next()
|
||
|
|
}, function (err) {
|
||
|
|
console.log('no more data')
|
||
|
|
})
|
||

## API
|
||
|
|
|
||
|
|
#### `each(stream, iterator, cb)`
|
||
|
|
|
||
|
|
Iterate the data in the stream by calling the iterator function with `(data, next)`
|
||
|
|
where data is a data chunk and next is a callback. Call next when you are ready to
|
||
|
|
consume the next chunk. Optionally you can call next with an error to destroy the stream
|
||
|
|
|
||
|
|
When the stream ends/errors the callback is called if provided
