A Fastify plugin for loading and executing WebAssembly modules.

### Install

```shell

npm i fastify-wasm

```

### Usage

This plugin enables you to load and execute WebAssembly modules within a Fastify application. Simply register the plugin and provide the path to your WebAssembly file.

```js

"use strict";

const fastify = require("fastify")

const fastifyWasm = require("fastify-wasm")

const app = fastify()

app.register(fastifyWasm, {

  path: 'path/to/your/wasm',

})

app.listen({ port: 3000 }, (err) => {

  if (err) throw err;

});

```

### TypeScript

This plugin includes TypeScript definitions for better type safety and improved developer experience.

Exports from the WebAssembly module can be typed on the `FastifyWasmExports` interface.

```ts

import fastify from "fastify";

import fastifyWasm from "fastify-wasm";

interface FastifyWasmExports {

  add(lhs: number, rhs: number): number

}

const app = fastify();

app.register(fastifyWasm, {

  path: 'path/to/your/wasm',

});

app.get('/', (_req, reply) => {

  // Call the exported function `add` from the wasm module

  const { add } = fastify.wasm.instance.exports

  reply.send({ result: add(2, 2) })

})

app.listen({ port: 3000 }, (err) => {

  if (err) throw err;

});

```
