Yeoman generator for game jam projects (Phaser)

Usage no npm install needed!

<script type="module">
  import generatorGamejam from '';



This is a Yeoman generator for game jam HTML5 projects. With this you can quickly create a project skeleton that contains:

  • An index.html file that displays your game using the awesome Phaser game framework.
  • A local web server you can run your game into (needed for Phaser).
  • Developer tools: Gulp, Browserify, livereload.
  • A task to create a release of your game that you can zip or backup.
  • A task to deploy your game into your own server online.

Getting Started

You need to install both Yeoman and this generator globally:

npm install -g yo generator-gamejam

Create a directory for your project and run yeoman from within:

mkdir awesome-game
cd awesome-game
yo gamejam

You will get this project skeleton:

├── src
│   ├── images
│   │   ├── phaser.png
│   │   └── preloader_bar.png
│   ├── index.html
│   ├── raw.html
│   ├── js
│   │   ├── main.js
│   │   └── play_scene.js
│   └── styles.css
├── gulp.config.json
├── gulpfile.js
├── node_modules
└── package.json

You will see a gulpfile.js, which is to setup Gulp, a task automator and building system. It is very useful to speed up our workflow.

Developing your game


This project includes Browserify, a tool for managing dependencies and modules (like RequireJS). One of the cool things about Browserify is that it allows you to use node modules in your browser application. For instance, if you need Lo-Dash in your project, you would install it as a regular npm package:

npm install lodash-node

And then in your JavaScript files, you would just need:

var _ = require('lodash-module');

You can require local files too in this fashion, but you need to put a path (relative to the current file):

var PlayScene = require('./play_scene.js');

Running the game

In the gulpfile.js there are defined some tasks to aid development. The default task will build the project in a dist folder.


You can now run a local server over dist. For instance:

npm -g install http-server
http-server dist

Now open and you will see a "Hello, world" game.

However, while you are developing, you will want to use the run task. This is similar to the default task, but will watch your JS files for changes and re-run Browserify automatically. This also uses browser-sync to reload your browser automatically whenever there are changes to JavaScript, HTML or CSS files.

gulp run

Releasing and deploying

You can create a build, which will create a directory with only your project files ready to be distributed.

gulp dist

Embedding your game

There are several places you can submit your game to, like or Ludum Dare. These websites have their own wrapper or viewer over your game. That's why raw.html exists: it is the bare game ready to be embedded in an iframe.

1.2.0 (12 Feb 2016)

  • Used browser-sync instead of relying on live-reload.
  • Added file to the scaffolding
  • Added deployment with Github Pages
  • Made deployment optional
  • Fixed gulp not running when config.local.json could not be found

1.1.0 (1 May 2015)

  • Used gulp-livereload.
  • Now the game itself is in its own html file (raw.html) so it can be embedded into an iframe by third-party websites.
