wasm-bindgen/examples/README.md

Examples

This directory contains a number of examples of the #[wasm_bindgen] macro and how to display them in the browser. Each directory contains a README with a link to https://webassembly.studio so you can also explore the example online (apologies if they're out of sync!), and each directory also contains a build.sh which assembles all the relevant files locally. If you open up index.html in a web browser you should be able to see everything in action when using build.sh!

The examples here are:

• add - an example of generating a tiny wasm binary, one that only adds two numbers.
• asm.js - an example of using the wasm2asm tool from binaryen to convert the generated WebAssembly to normal JS
• char - an example of passing the rust char type to and from the js string type
• closures - an example of how to invoke functions like setInterval or use the onclick property in conjunction with closures.
• comments - an example of how Rust comments are copied into js bindings
• console_log - a showcase of #[wasm_bindgen] importing classes and how to bind console.log
• dom - an example of accessing the global document object and appending HTML to it
• fetch -- how to use the Fetch API to make async http requests
• hello_world - the "hello world" of #[wasm_bindgen], aka throwing up a dialog greeting you
• import_js - an example of importing local JS functionality into a crate
• math - like console_log except showing how to import Math-related functions instead
• no_modules - an example of how to use the --no-modules flag to the wasm-bindgen CLI tool
• performance - how to import APIs like performance.now() and time various operations in Rust
• smorgasboard - a bunch of features all thrown into one, showing off the various capabilities of the #[wasm_bindgen] macro and what you can do with it from JS
• wasm-in-wasm - how to interact with namespaced APIs like WebAssembly.Module and shows off creation of a WebAssembly module from Rust
• webaudio - how to use the Web Audio APIs to generate sounds
