Serial and parallel runner for asynchronous functions

Serial

Serial is a Node.JS module to serially/sequentially run asynchronous functions.

It also includes a Parallel runner to simultaneously run asynchronous functions.

Usage

var SerialRunner = require("serial").SerialRunner; var runner = new SerialRunner();

runner.add(function1, param1).add(function2, param2); runner.add(function3, param3);

runner.onError(function(err) { runner.stop(); // stop further queued function from being run console.log("There was an error"); });

runner.run(function() { console.log("done"); });

function function1(param, callback) { // do smthg

if("something went wrong") {
  var err = new Error("something went wrong");
  callback(err);
} else {
  callback();
}

}

var ParallelRunner = require("serial").ParallelRunner; var runner = new ParallelRunner();

runner.add(function1, param1).add(function2, param2); runner.add(function3, param3);

runner.run(function() { console.log("done"); });

function function1(param, callback) { // do smthg callback(); }
