Flowsync.js

An ES6 flow control component.

import flowsync from "flowsync";

let functionCollection = [
  function (ready) {
    setTimeout(ready, 100);
  },
  function (ready) {
    setTimeout(ready, 100);
  },
  function (ready) {
    setTimeout(ready, 100);
  }
];

flowsync.series(functionCollection, function finalCallback(error, results) {
  // do something after 300 ms
});

Quality and Compatibility

Every single build and release is automatically tested on the following platforms:

If your platform is not listed above, you can test your local environment for compatibility by copying and pasting the following commands into your terminal:

npm install flowsync
cd node_modules/flowsync
gulp test-local

Installation

Copy and paste the following command into your terminal to install Flowsync:

npm install flowsync --save

Import / Require

// ES6
import flowsync from "flowsync";

// ES5
var flowsync = require("flowsync");

// Require.js
define(["require"] , function (require) {
    var flowsync = require("flowsync");
});

Getting Started

//ES6

flowsync.series([
    (next) => {
      //do something
      next(null, 1);
    },
    (next) => {
      next(new Error("some error"));
    }
  ], (error, results) => {
    //do something after the series
  });

//ES5

flowsync.series([
    function stepOne(next) {
      //do something
      next(null, 1);
    },
    function stepTwo(next) {
      next(new Error("some error"));
    }
  ], function finalStep(error, results) {
    //do something after the series
  });

Function list

They all work pretty much similar. For a detailed interface documentation take a look to the async repo. These is the list currently supported by flowsync:

• series(functionArray, finalCallback)
• parallel(functionArray, finalCallback)
• mapSeries(array, iteratorFunction[item, cb], finalCallback)
• mapParallel(array, iteratorFunction[item, cb], finalCallback)
• eachSeries(array, iteratorFunction[item, cb], finalCallback)
• eachParallel(array, iteratorFunction[item, cb], finalCallback)

How to Contribute

You can submit your ideas through our issues system, or make the modifications yourself and submit them to us in the form of a GitHub pull request.

We always aim to be friendly and helpful.

Running Tests

It's easy to run the test suite locally, and highly recommended if you're using Flowsync.js on a platform we aren't automatically testing for.

npm test

SauceLabs Credentials

We've setup our tests to automatically detect whether or not you have our saucelabs credentials installed in your environment (process.env.SAUCE_USERNAME).

If our saucelabs credentials are not installed, the tests are setup to automatically detect all browsers you have installed on your local system, then use them to run the tests.

Obtaining Our SauceLabs Credentials

If you'd like to develop Flowsync.js using SauceLabs, you need only create a new entry in our issue tracker asking for our SauceLabs credentials.

We'll send over all credentials specific to this project so that you can perform comprehensive cross-platform tests.
