wasm-bindgen/examples/asm.js/README.md
Alex Crichton dadcff15ef Add an example of wasm2asm and wasm-bindgen 
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.

WebAssembly to asm.js

This directory is an example of using binaryen's wasm2asm tool to convert the wasm output of wasm-bindgen to a normal JS file that can be executed like asm.js.

You can build the example locally with:

$ ./build.sh

When opened in a web browser this should print "Hello, World!" to the console.

This example uses the wasm2es6js tool to convert the wasm file to an ES module that's implemented with asm.js instead of WebAssembly. The conversion to asm.js is done by binaryen's wasm2asm tool internally.

Note that the wasm2asm tool is still pretty early days so there's likely to be a number of bugs to run into or work around. If any are encountered though please feel free to report them upstream!
