# Calling Rust from NodeJS
This is a example for calling **wasm** `Rust` function from `NodeJS`.
## Requirements
- **node**
-
- **wasm-bindgen-cli**
-
- **cargo make (optional, can be run manually)**
-
## How to run?
1. Install the node dependencies
```bash
npm install
```
2. Build the wasm
```bash
cargo make build
```
3. Starts the nodejs server
```bash
npm run start
```
> After that **GET** or **POST** to the `http://localhost:3000`
## Manual run
After installing the node dependencies:
1. Build to wasm32
- `cargo build --target wasm32-unknown-unknown`
2. Bundle the wasm
- `wasm-bindgen --typescript --target nodejs --out-dir src/pkg target/wasm32-unknown-unknown/debug/rust_wasm_nodejs.wasm`
3. Starts the node server
- `npx tsx src/index.ts`
