Info

• We can integrate Rust with Node through native addons, as we would with C++.

• To do this, we have to interact with Javascript through C. We compile a Rust library using C interfaces and bindings. The library is in different formats depending on the operating system.

• To do all the hard work, we use the crate called NAPI, which is responsible for making the interfaces and bindings with C and exporting the functions for use in Javascript.

NAPI crate

• NAPI => https://napi.rs/

• NAPI Crate => https://crates.io/crates/napi

• NAPI GitHub => https://github.com/napi-rs/napi-rs

• NAPI Examples => https://github.com/napi-rs/napi-rs/tree/main/examples

How to use the native addon

• Create/open a javascript/typescript project.

• Install the package using npm install wtools-rust. The main package will install the right dependency for your OS automatically.

• Import the package and call the function (Typescript snippet, functions have ts types generated during the compilation):

import { uuid } from "./index";

const uuidRandom = uuid() // Generate random uuid

const uuidInput = uuid('asdfadfsadsf') // Generate uuid using hash SHA256 with the input text
