Targeting HTML5 with Haxe

The web is one of the most accessible and powerful platforms — and Haxe makes it a first-class citizen. Whether you're building browser games, rich tools, or full desktop apps with Electron, the HTML5 target gives you flexibility and reach.

Write in Haxe, Run in the Browser

Haxe compiles to clean, efficient JavaScript that works across all major browsers. Strong typing, powerful macros, and readable output make it ideal for frontend development without the chaos of raw JS.

• Standard JS Output
• Full JS Interop
• Zero Runtime Bloat

Canvas & WebGL Support

Whether you're drawing UI with Canvas 2D or building advanced effects with WebGL, Haxe offers multiple paths to fast visual rendering. Libraries like OpenFL, Kha, or even raw WebGL give you total control.

• Canvas 2D support
• Full WebGL integration
• Shader support via GLSL

WebAssembly (WASM)

When performance is everything, Haxe can target WebAssembly through its C++ backend. Perfect for simulations, physics, video decoding, or math-heavy workloads — now right in the browser.

• High-performance native logic via WASM
• Ideal for C++ integration or heavy computation
• Progressively adoptable in modern apps

Electron for Desktop Apps

Want to take your HTML5 app and run it on the desktop? Haxe + Electron is a perfect combo. Use the same codebase to deliver native-like experiences across Windows, macOS, and Linux.

• Bundle web apps as native executables
• Access filesystem, background services, and OS APIs
• Maintain a single frontend codebase

Use Cases

• Browser-based games and simulations
• In-browser IDEs or visual tools
• Cross-platform desktop apps via Electron
• Web-first tools with offline modes

One Stack, Many Surfaces

Haxe's HTML5 target gives you unmatched reach: the web, the desktop, the canvas, and even WebAssembly — all from one codebase. You don't need multiple languages or toolchains to build powerful web and desktop experiences.
