# Rust WASM in Google Appsscripts
- Original Repository [https://github.com/googleworkspace/apps-script-samples/tree/main/wasm/hello-world](https://github.com/googleworkspace/apps-script-samples/tree/main/wasm/hello-world)

- Additional resource: [Rust to WebAssembly the hard way](https://surma.dev/things/rust-to-webassembly/)
How to:
1. You will need to use cargo to build your Rust code.
```
cargo build --target wasm32-unknown-unknown --release
```
2. You will need to use wasm-bindgen to generate the JavaScript bindings for your Rust code.
```
wasm-bindgen \
--out-dir src/pkg \
--target bundler \
./target/wasm32-unknown-unknown/release/wasm_test.wasm
```
3. You will need to use wasm-opt to optimize your WebAssembly module. This is optional but recommended.
```
wasm-opt \
src/pkg/wasm_test_bg.wasm \
-Oz \
-o src/pkg/wasm_test_bg.wasm
```
4. You will need to use a bundler such as ESBuild to bundle your JavaScript code and WebAssembly module.
```
node build.js
```
## Deployment
Add `src/main.js` and `dist/wasm.js` to your Appsscripts project.
## Additional Resources
Added following options to `Cargo.toml` according to [Rust to WebAssembly the hard way](https://surma.dev/things/rust-to-webassembly/):
```
[profile.release]
opt-level = 's'
strip = "debuginfo"
lto = true
```
