Code for my blog post about getting started with React and Rust/wasm

react_rust_wasm's Issues

Suggested update to blog post - Freeze dependencies

Hi there. I am trying the tutorial from your react_rust_wasm tutorial. When I tried to run your tutorial verbatim, I got errors running npx webpack.

However, once I copied your exact package.json from this repo and ran npm i on that, npx webpack ran fine.

So my suggestion is, update the blog post to specify what versions to install with npm install, or tell readers to just use your exact package.json file.

Thanks!

unable to `npm run build-wasm`

I have been following your tutorial but have been unable to get past the build-wasm stage

There appears to be an issue with proc_macro_span

How can I run a web-server from the dist directory?
