js13k Webpack Starter

What is it?

This project aims to be a foundation for creating a game for the js13k game competition. As such it provides tools such as a development server, automatic code minification and archive creation.

List of features

  1. JS & CSS minification
  2. Code inlining (the entire application is a single index.html file)
  3. Development server with source maps
  4. Generation of submission files (including the .zip file)
  5. ES2015 module support through webpack
  6. Tree shaking and module concatenation

How can I get started?

The first thing you need to do is make sure you have node.js installed. Then clone the project and in the root directory run the following command:

npm install

This should install all the required dependencies for developing the project. After the installation finishes you will be able to run the included npm scripts.

How can I start the development server?

After going through the installation just run the following command:

npm start

This will setup a server listening at http://localhost:8080/.

Access from another device

You can pass an argument to the development server specifying the interface to listen on.

npm start -- --host=0.0.0.0

This command will start the development server listening on all interfaces. Having a device on the same network you will be able to view the webpage at http://[yourLocalIP]:8080 for example http://192.168.1.1:8080.

How can i generate files for submission?

This project provides a npm script for building your application. Just run:

npm run build

This will generate two files index.html and build.zip both located in the dist/ folder. The zip file contains only the generated index.html. The output from the command also tells you how large is the generated zip file.

Where does my code go?

All your javascript files should be located in the src/app/ directory. The entry point is the main.js file. All your css should be located in the src/styles directory. The entry point is main.css. If you need to modify the html file, you can find the template used in src/index.html.

This project uses webpack for module bundling. This means that all the files that you want to use should be imported directly or indirectly by either main.js or main.css.

ES2015+ support

This repository used to include Babel to enable working with modern JavaScript. As time progresses however the browser support for modern JS became excelent and webpack began shipping a newer version of uglify that can minify it. All of this makes it a rational choice to omit Babel as it would only increase the overall bundle size.
