map-stream-limit

Like map-stream but with a concurrency limit.

Example

var map = require("map-stream-limit");
 
map(function(data, callback) {
    // Do some async stuff here
    // But limited to 5 at a time
}, 5);

API

map(asyncFn, limit)

Create a map-stream with the given asynchronous function but no more than the given limit will be running at any given time.

A "drain" event will be emitted when the internal buffer is empty and the last remaining item being processed is finished.

Installation

npm install map-stream-limit
