Build Status



Just the beginning, and learning Rust... come back in a year or so?


Requires specifying either webgl_1 or webgl_2 in features

Other than that, depend as usual via cargo and check out the docs


awsm is a collection of helpers for doing wasm in Rust

There are two different goals:

  1. Incubating and testing out ideas that might move to gloo at some point

An example of this would be the start_raf_ticker() function, as well as most of the direct webgl functions.

Moving these into gloo and deprecating them here would be considered a good thing! If/when that happens, the original function might be kept around as a backwards compatible shim.

  1. Opinionated ideas that are a bit too opinionated to be universal defaults.

An example of this would be the webgl_renderer.

It makes sane choices about how to cache various lookups, for example, but not every project would want that hardcoded.


There are two steps:

  1. run watch-dev.bat in the main folder.

This will watch for changes to rust sources and rebuild / bindgen to create the wasm on change

Usually this is the window to look at for iterative feedback

This is required to cause changes to be reloaded (npm start isn't enough)

  1. cd examples && npm start

This will start up the webpack dev server (and it will restart when rust recompiles successfully)

The reason these are kept separate is that I found the best way is to keep them in completely separate windows. The webpack dev server generates its own noise and does weird coloring stuff.

There could theoretically be different settings for "watch-dev" i.e. to only run cargo check etc. but I haven't really needed that yet

Anyway, made sense to keep the steps separate :)

Sorry watch-dev is a bat. Could easily be made into .sh or whatever. Also it's not in npm scripts since it's nice to just double-click it ;)

  1. Edit examples/Cargo.toml to switch between webgl1 and webgl2

It's changing one character, but you can only test one at a time (since it's a compile-time flag)


For the app example - npm run bundle in the examples folder should cover it

But make sure wasm-opt is installed by downloading the latest release from binaryen and putting it in the path somewhere

For the library - it's just normal cargo package/publish in the lib/ folder

Live Coding

As a way to self-motivate getting over the learning curve (this is my first Rust project), I thought it might help to livestream the coding+learning sessions, and also archive them in a playlist for a look-back.
