How do I publish a Kiwi.js game to the iOS App Store?

Use the integrated CocoonJS framework to compile your HTML5 game into a native app. You'll need a Ludei account and must follow CocoonJS's submission process, which handles much of the packaging.

Kiwi.js vs Phaser: which is better for 2D games?

Kiwi.js shines with fast WebGL rendering and CocoonJS integration for mobile apps, while Phaser has a larger community and more frequent updates. Choose Kiwi.js if mobile publishing is critical; Phaser for broader support and tutorials.

How to add physics to a game in Kiwi.js?

Attach the arcade physics component to your game objects. Since Kiwi.js uses an entity/component system, you can easily add physics by including the component in your entity's setup during the create phase.

Does Kiwi.js support TypeScript?

Yes, Kiwi.js has TypeScript modules for plugin development, as noted in v1.4.0. The source is written in TypeScript, and definition files (kiwi.d.ts) are generated during the build process.

What's the performance like on older browsers?

Kiwi.js uses a canvas fallback for browsers without WebGL support, but performance may degrade. The framework is optimized for modern browsers with hardware acceleration.

How to optimize rendering in Kiwi.js for better FPS?

Use properties like Geom.Transform.ignoreChild for static objects to save matrix operations, and leverage caching techniques mentioned in v1.4.0, such as render pipeline optimizations.

What is Kiwi.js?

Kiwi.js is an open-source HTML5 game framework built for creating high-performance 2D games that run in mobile and desktop browsers. It solves the problem of complex game development by providing a fast WebGL renderer, a modular entity/component system, and tools for publishing games as native apps via CocoonJS.

Target Audience

Game developers and indie studios looking to build cross-platform HTML5 games with professional rendering capabilities and easy mobile deployment.

Value Proposition

Developers choose Kiwi.js for its focus on speed through WebGL optimization, its extensible plugin architecture, and its tight integration with CocoonJS for hassle-free app store publishing.

Overview

Kiwi.js is a blazingly fast mobile & desktop browser based HTML5 game framework. It uses CocoonJS for publishing to the AppStore.

Use Cases

Best For

Creating 2D browser games with hardware-accelerated graphics
Developing mobile games deployable as native iOS/Android apps
Building games with modular entity/component architectures
Prototyping games quickly with built-in state management
Extending game engines with custom WebGL shaders or plugins
Publishing HTML5 games to multiple platforms from a single codebase

Not Ideal For

Projects requiring 3D graphics or advanced 3D rendering beyond 2D capabilities
Teams needing a framework with a large, active community and frequent modern feature updates
Developers who avoid vendor lock-in and prefer flexible mobile publishing options outside CocoonJS

Pros & Cons

Pros

Blazing Fast WebGL Rendering

Uses a custom WebGL renderer with optimizations like matrix concatenation caching, offering 10-50% performance gains as highlighted in the v1.4.0 release notes.

Easy Mobile App Publishing

Seamlessly integrates with CocoonJS to wrap HTML5 games as native iOS and Android apps, simplifying cross-platform deployment.

Modular Entity/Component System

Game objects are entities with attachable components like physics or animation, promoting code reusability and maintainability.

Comprehensive State Management

Provides a flexible state system with configurable preload, create, update, and destroy phases, easing game logic organization.

Cons

Vendor Lock-in for Mobile

Heavy reliance on CocoonJS for native app publishing ties developers to a specific service, risking flexibility if the service changes or discontinues.

Outdated and Limited Ecosystem

With version 1.4.0 as the last major release and no recent updates mentioned, the framework may lack modern features and have a smaller plugin repository.

Complex Setup for Newcomers

Requires setting up a web server (e.g., XAMPP) and using build tools like Grunt or Visual Studio, which can be intimidating for beginners.
