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

SerialRunner

  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();
    }
  }

Parallel Runner

  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();
  }
