Installation Setup
Install via npm: npm install phaser
Or include via CDN: <script src='https://cdn.jsdelivr.net/npm/phaser@3/dist/phaser.min.js'></script>
Set up a basic index.html with a canvas container
Initialize a Phaser.Game instance with configuration
Create and configure Scenes, preload assets, and add game objects
Environment Setup
Modern browser with WebGL support
Node.js for npm package management
Optional bundler for production
Assets ready for preload
Editor or IDE for JS/TS development
Config Files
index.html - canvas container
main.js - Phaser game initialization
assets/ - images, audio, tilemaps
scenes/ - individual scene scripts
utils/ - helper functions and plugins
Cli Commands
npm install phaser -> install Phaser
yarn add phaser -> alternative install
Use bundlers (Webpack/Rollup/Vite) for production
Run development server for live testing
Deploy bundled game to web host
Internationalization
Text rendered in-game can be localized
Assets can be swapped per language
No engine-imposed restrictions on language
Strings managed externally via JSON or resource files
Supports multi-language games globally
Accessibility
Phaser itself is canvas-based and limited for accessibility
Use HTML overlays for screen readers
Keyboard input supported for navigation
Respect reduced motion preferences externally
Provide alternative content when needed
Ui Styling
HTML/CSS for external UI
Phaser Game Objects for in-canvas UI
Text objects for labels and HUD
Images and sprites for buttons
Overlay DOM elements optional for complex UI
State Management
Scene manages state of Game Objects
Physics engine updates object positions
Input events update state
Tweens modify object properties over time
Custom global state can be managed in game config
Data Management
Assets preloaded and cached
Tilemaps stored as JSON
Sprite atlases for optimization
Audio assets loaded and managed
Physics and input state handled per scene
