Hi all!
I just built my first Rust + WebAssembly browser app — a Markdown-to-HTML converter with live preview, theme switching, and a styled UI. It uses pulldown-cmark in Rust, compiled to WASM, and runs entirely in the browser.

It’s mostly CSS and UI styling, but the core logic is Rust-powered and it’s my first time trying WASM.

GitHub repo: https://github.com/Pjdur/myfirstwasm

Setup instructions:

1. Make sure you have Rust and wasm-pack installed.
2. Clone the repo:

   git clone https://github.com/Pjdur/myfirstwasm
   cd myfirstwasm
   

3. Build the WASM package:

   wasm-pack build --target web
   

4. Serve it locally (you need a server because browsers block .js (needed to execute the wasm) over file://):

   cargo install miniserve
   miniserve .
   

   Or use Python:

   python -m http.server 8080
   

Features:

• Live Markdown editing
• Toggle between rendered and raw HTML
• Theme switcher (light/dark/violet)
• Styled code blocks (no JS libraries)
• Built with Rust + wasm-bindgen

Would love feedback, ideas, or just sharing in case it helps someone else get started with Rust + WASM!
