Phaser3 + Parcel Template

For people who want to spend time making games instead of configuring build tools.

Prerequisites

You'll need Node.js, npm, and Parcel installed.

It is highly recommended to use Node Version Manager (nvm) to install Node.js and npm.

For Windows users there is Node Version Manager for Windows.

Install Node.js and npm with nvm:

nvm install node

nvm use node

Replace 'node' with 'latest' for nvm-windows.

Then install Parcel:

npm install -g parcel-bundler

Getting Started

Clone this repository to your local machine:

git clone https://github.com/ourcade/phaser3-parcel-template.git

This will create a folder named phaser3-parcel-template. You can specify a different folder name like this:

git clone https://github.com/ourcade/phaser3-parcel-template.git my-folder-name

Go into your new project folder and install dependencies:

cd phaser3-parcel-template # or 'my-folder-name'
npm install

Start development server:

npm run start

To create a production build:

npm run build

Production files will be placed in the dist folder. Then upload those files to a web server. 🎉

Project Structure

    .
    ├── dist
    ├── node_modules
    ├── public
    ├── src
    │   ├── scenes
    │   │   ├── HelloWorldScene.js
    │   ├── index.html
    │   ├── main.js
    ├── package.json

The contents of this template is the basic Phaser3 getting started example.

This template assumes you will want to organize your code into multiple files and use modern JavaScript (or TypeScript).

JavaScript files are intended for the src folder. main.js is the entry point referenced by index.html.

Other than that there is no opinion on how you should structure your project. There is a scenes folder in src where the HelloWorldScene.js lives but you can do whatever you want.

Static Assets

Any static assets like images or audio files should be placed in the public folder. It'll then be served at http://localhost:8000/images/my-image.png

Example public structure:

    public
    ├── images
    │   ├── my-image.png
    ├── music
    │   ├── ...
    ├── sfx
    │   ├── ...

They can then be loaded by Phaser with this.image.load('my-image', 'images/my-image.png').

Class Properties Support

If you want to use the modern ES6 class properties feature then you'll need to add a .babelrc file at the project root with the @babel/plugin-proposal-class-properties plugin.

{
	"presets": [
		"env"
	],
	"plugins": [
		"@babel/plugin-proposal-class-properties"
	]
}

Parcel should automatically install the necessary dependencies.

If you run into an error about mismatched major versions then go into package.json to see what the major versions for @babel/core and @babel/plugin-proposal-class-properties are.

Reinstall one or the other manually to make the versions match 😉

TypeScript

Check out the phaser3-typescript-parcel-template for a ready-to-use version of this template in TypeScript!

---

It just works. (Thanks to Parcel)

You can rename all the .js files to .ts and start using TypeScript.

You may also want to add a tsconfig.json file to the project root like this:

{
	"compilerOptions": {
		"target": "es2016",
		"module": "es6",
		"strict": true,
		"noImplicitAny": false,
		"noEmit": true,
		"allowJs": true,
		"jsx": "preserve",
		"importHelpers": true,
		"moduleResolution": "node",
		"experimentalDecorators": true,
		"esModuleInterop": true,
		"allowSyntheticDefaultImports": true,
		"sourceMap": true,
		"baseUrl": "./src",
		"paths": {
		  "~/*": ["./*"]
		},
		"typeRoots": [
			"node_modules/@types",
			"node_module/phaser/types"
		],
		"types": [
			"phaser"
		]
	},
	"include": [
		"src/**/*"
	]
}

More information on tsconfig.json options here.

Note on how Parcel handles baseUrl and paths.

Flow

It just works. (Thanks to Parcel)

Just put // @flow at the top of your .js files. Parcel will handle the rest.

Go here for more information on how to use Flow.

Dev Server Port

You can change the dev server's port number by modifying the start script in package.json. We use Parcel's -p option to specify the port number.

The script looks like this:

parcel src/index.html -p 8000

Change 8000 to whatever you want.

Other Notes

parcel-plugin-clean-easy is used to ensure only the latest files are in the dist folder. You can modify this behavior by changing parcelCleanPaths in package.json.

parcel-plugin-static-files is used to copy static files from public into the output directory and serve it. You can add additional paths by modifying staticFiles in package.json.
