Modern WebAssembly Learning Repository

Welcome! This repository is designed to be a top-tier, modern resource for learning WebAssembly (WASM) in 2025. Our goal is to provide clear explanations, practical examples, and up-to-date information to help you master WASM.

For detailed documentation, please see the docs directory.

This repository is organized into the following main directories:

• /docs: Contains detailed documentation, guides, and conceptual explanations.
• /src: Will house core library code or reusable modules (currently planned).
• /examples: Provides practical, hands-on examples of WebAssembly in action.
  • FFmpeg GIF Maker: A TypeScript example demonstrating video to GIF conversion using FFmpeg.wasm. (See examples/ffmpeg/gif_maker/ts)
  • C to WASM (Factorial): A simple example showing how to compile a C function (factorial) to WASM using Emscripten and call it from JavaScript. Details here.
  • Rust to WASM (Add & Greet): A basic example demonstrating how to compile Rust functions to WASM using wasm-pack and wasm-bindgen, then call them from JavaScript. Details here.
  • Go to WASM (Concat & Add): A basic example demonstrating how to compile Go functions to WASM using standard Go tooling (GOOS=js GOARCH=wasm) and call them from JavaScript. Details here.
  • C# to WASM (Greet, Add & Complex Calc): A basic example demonstrating how to compile C# methods to WASM using the .NET SDK (browser-wasm target) and call them from JavaScript. Details here.
  • Swift to WASM (Greet & Add): A basic example demonstrating how to compile Swift functions to WASM using SwiftWasm (carton build tool) and JavaScriptKit for interop. Details here.
• /tests: Will include tests for any code developed in /src or /examples.
• /build: Will be used for build artifacts and outputs.
• /scripts: Contains utility scripts for building, testing, or managing the repository.
