1.0.20 • Public • Published


Vegas JS - version 1.0.19 is an Opensource Framework based on ECMAScript for develop crossplatform Rich Internet Applications and Games.

This project contains a set of libraries writing in Javascript and based on the ES6 standard :

package description
core The core package is specialized in functions utilities that are highly reusable without creating any dependencies : arrays, strings, chars, objects, numbers, maths, date, colors, etc.
system The system package is the root for the VEGAS JS framework. It is the starting point of our RIA framework structure : signals, W3C events, datas and collections (ADT), IoC container (Dependency Injection), logger, tasks, transitions, logics, rules, models, etc.
graphics The graphics library is an intuitive graphics API to manipulate all display objects in your applications. Offers a lot of powerful functionality to create and work with graphics, colors and geometrics objects, all neatly wrapped up in a well designed, consistent and clean programming interface.

You can install VEGAS JS with NPM or Yarn.

$ yarn add vegas-js --dev


$ npm install vegas-js --save-dev

Building and test the libraries

VEGAS JS use Yarn with a serie of powerful packages (Babel, Mocha, etc.) to compile and build this library.

⌜ Simple Build

1 - The first time, initialize the project and run yarn :

$ yarn

2 - Test + compile all the libraries :

$ yarn build

⌜ VEGAS (only) Build

1 - Build the ./dist/vegas.js : not minified + no comments + sourcemap.

$ yarn dev

2 - Build the ./dist/vegas.js and watch the changing into the ./src folder.

$ yarn watch

3 - Build the ./dist/vegas.min.js : minified + no comments.

$ yarn prod

4 - Build the ./dist/vegas.min.js and the ./dist/vegas.js libraries only.

$ yarn vegas

⌜ Molecule

Molecule is an advanced extension of VEGAS JS to develop rich applications based on the standard DOM UI, A-Frame or PIXI JS.

1 - Build the ./dist/vegas.molecule.js : not minified + no comments + sourcemap.

$ yarn molecule-dev

2 - Build the ./dist/vegas.molecule.js and watch the changing into the ./src folder.

$ yarn molecule-watch

3 - Build the ./dist/vegas.molecule.min.js : vegas + molecule + minified + no comments.

$ yarn molecule-prod

4 - Build all the vegas+molecule libraries only.

$ yarn molecule

Note : See all the examples of the molecule library in the examples/ folder of the project.

⌜ Examples

To launch the VEGAS HTML examples, use the command :

$ yarn example ./examples/molecule/pixi/basic.html

This command launch with the BrowserSync tool the html page of the example in your browser.

⌜ Unit tests

We use the Mocha and the Chai ( tools to run the unit tests of the VEGAS JS libraries.

1 - Run all unit tests

$ yarn test

2 - Run a specific library, use one of this command :

$ yarn test-core
$ yarn test-system
$ yarn test-graphics
$ yarn test-molecule

The --match option trigger the unit test engine (based on Mocha) to only run tests matching the given pattern which is internally compiled to a RegExp, for examples :

$ yarn test -g graphics

Run all the graphics package unit tests.

$ yarn test -g graphics.CardinalDirection
$ yarn test -g core.arrays.contains

Run only the graphics.CardinalDimension unit tests or the core.arrays.contains module unit tests.

The --reporter option define the unit test result rendering in the terminal with the values : 'spec', 'dot', 'landing', 'dot', 'nyan', 'list', 'mochawesome'. By default the 'spec' value is used.

$ yarn test --reporter nyan


⌜ Generates the documentation

The documentation of the framework is based on JSDoc.

Run the documentation build with gulp :

$ yarn doc

The documentation is generated in the folder : ./docs/bin
