⚙️ Hello WASM on Firebase

Here’s a (rare) working example for WASM on Firebase Cloud Function (NodeJS) with wasm-bindgen. It should be a good starter for ordinary NodeJS target too.

WASM on Firebase Cloud Function

TLDR;

GitHub - katopz/hello-firebase-wasm: POC WASM on Firebase Cloud Function

Initialize

# Setup Firebase
npm install -g firebase-tools
firebase init
firebase login
# Setup Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Setup Cargo
cargo install cargo-watch
# Setup WASM
cargo install -f wasm-bindgen-cli

Develop

# To watch and build WASM from Rust
cd wasm
cargo watch -- . ./dev.sh
# To run WASM with Firebase
cd functions
npm run dev

Done!

And yes! I’m now in love withRust and WebAssembly So much fun! :)
