# Call Node.js functions from Rust

## Prerequisite

Must have Node.js installed with the following packages.

```
npm i ssvm sync-request better-sqlite3
npm i -g ssvmup
npm i -g wasm-pack
```

## How to use

Add cargo dependency

```
[dependencies]
nodejs-helper = "0.0.3"
```

Make Node.js Javascript API calls from Rust code!

```
#[wasm_bindgen]
pub fn utc_now() {
  let now: String = nodejs_helper::date::utc_string();
  nodejs_helper::console::log("UTC time: ");
  nodejs_helper::console::log(&now);
}
```

The Rust code must be compiled to WebAssembly and run from inside Node.js. [See how](https://cloud.secondstate.io/server-side-webassembly/getting-started)
