This commit adds an example of executing the `wasm2asm` tool to generate asm.js output instead of WebAssembly. This is often useful when supporting older browsers, such as IE 11, that doesn't have native support for WebAssembly.

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:
hello_world
- the "hello world" of#[wasm_bindgen]
, aka throwing up a dialog greeting youconsole_log
- a showcase of#[wasm_bindgen]
importing classes and how to bindconsole.log
math
- likeconsole_log
except showing how to import Math-related functions insteaddom
- an example of accessing the globaldocument
object and appending HTML to itsmorgasboard
- 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 JSperformance
- how to import APIs likeperformance.now()
and time various operations in Rustwasm-in-wasm
- how to interact with namespaced APIs likeWebAssembly.Module
and shows off creation of a WebAssembly module from Rustclosures
- an example of how to invoke functions likesetInterval
or use theonclick
property in conjunction with closures.no_modules
- an example of how to use the--no-modules
flag to thewasm-bindgen
CLI tooladd
- an example of generating a tiny wasm binary, one that only adds two numbers.asm.js
- an example of using thewasm2asm
tool from binaryen to convert the generated WebAssembly to normal JS
