Explore the essential tools and frameworks that enable WebAssembly development across languages and platforms.
Compile Rust to WebAssembly using wasm-pack for web integration and standalone applications. Our guide includes step-by-step instructions and optimization techniques.
// Cargo.toml
[lib]
crate-type = ["cdylib"]
[features]
# Use the `wee_alloc` feature to reduce the size of your WebAssembly binary
[dependencies]
wasm-bindgen = "0.2"
// Add this to your Rust code
use wasm_bindgen::prelude::*;
#[wasm_bindgen]
pub fn add(a: i32, b: i32) -> i32 {
a + b
}
Use Emscripten to compile native C/C++ applications to WebAssembly. Ideal for game engines, libraries, and legacy applications.
// Example emcc compile command
emcc mylib.cpp -O3 -s WASM=1 -s EXPORTED_FUNCTIONS="['_add'] -o my-libwasm.js
Use WebAssembly for efficient execution of smart contracts and blockchain-based computations across distributed environments.
Execute machine learning models in WebAssembly for privacy, portability, and performance optimization across cloud and edge devices.
Select the right toolchain for your project needs and start using WebAssembly to power the next generation of applications.
