Docker Image for wasm-pack

To use rust and webassembly requires installing a fair amount of tooling. I decided to create a docker image with everything required:

• rust 1.30
• wasm-pack
• cargo-generate
• nodejs
• yarn
• exposes port 8080 and port 5000

It is available on docker hub: https://hub.docker.com/r/rnsloan/wasm-pack/

To pull the image: docker pull rnsloan/wasm-pack:1.0.0.

wasm-pack

To use wasm-pack follow the guide here: https://rustwasm.github.io/wasm-pack/book/project-setup/using-a-template.html

JavaScript

For instructions on how to use .wasm files with JavaScript look at guides with JS bundling tools such as:

• a wasm-loader for webpack: https://github.com/ballercat/wasm-loader
• Using with parcel https://parceljs.org/webAssembly.html

Manually compiling .wasm files can be tedious. There are ways to make this automated:

• Parcel supports importing rust files directly https://parceljs.org/rust.html
• create-react-app style webpack boilerplates exist to handle all of the compiling stages such as https://github.com/rustwasm/rust-webpack-template
