game-setup-and-config

Create a Phaser.Game instance by passing a GameConfig object with a renderer type and at least one scene class. The minimal config uses type: Phaser.AUTO and a scene with preload and create methods, producing a default 1024x768 canvas.

Set pixelArt: true in the config, which automatically disables antialiasing and enables roundPixels for crisp scaled sprites. For WebGL-only smooth edges between blocky pixels, use smoothPixelArt: true instead.

Phaser.AUTO tries WebGL first and falls back to Canvas if unsupported, while Phaser.WEBGL forces WebGL with no fallback and fails silently if unavailable. Use AUTO unless you specifically require WebGL features.

Yes, Phaser.Scale.FIT fits the canvas inside its parent while preserving aspect ratio, producing letterboxing. Use RESIZE to fill the parent ignoring aspect ratio, or ENVELOP to cover the parent with possible overflow.

The fps.target property is advisory only and does not enforce a frame rate cap. Use fps.limit to actually cap the frame rate, though the browser's display refresh rate remains the upper bound.

Use Phaser.HEADLESS for unit testing game logic without rendering output. It skips renderer creation but still requires a DOM environment, so it is not suitable for pure Node.js execution without a DOM shim.
