QRust

Generate QR codes with rust

Started off as a server-side app and now is a client side web-app using WASM!

inspired from this article by Kiran Johns and built with kennytm/qrcode-rs.

Compile WASM

1. Setup the environment for WASM compilation

rustup target add wasm32-unknown-unknown
rustup override set nightly
cargo install wasm-pack wasm-gc

2. Generate the WASM and bindings

wasm-pack build --target web
wasm-gc pkg/qrs_bg.wasm

View the Creation

1. Setup a web-server to host the following files & folders in particular:
   • index.html - The html that loads the app.
   • index.js - The JS that starts the show.
   • pkg/ - The package folder that houses our wasm and bindings generated with wasm-pack.
2. Open http://localhost:8080 in a browser.
