# wtrpc

Type safe node js worker threads

Define a contract `contract.ts`

```typescript

type RpcContract = {

    scan: (req: {pid: number, pattern: string}) => number[]

}

```

Implement the contract as a worker 

`worker.ts`

```typescript

import { WorkerRpc } from '@wtrpc/core'

import { RpcContract } from './contract.js'

import { parentPort } from 'node:worker_threads';

const worker = new WorkerRpc({

    scan(req: {pid: number, pattern: string}): number[] {

        return [-1]

    }

})

// Bind the worker to the worker_thread parent port if it exists

if (parentPort) worker.bind(parentPort);

```

`pool.ts`

```typescript

import { WorkerRpcPool } from '@wtrpc/core'

import { RpcContract } from './contract.js'

const workerUrl = new URL('./worker.js', import.meta.url);

const threadCount = os.cpus().length;

const pool = new WorkerRpcPool(threadCount, workerUrl);

// Run the task on the worker thread pool

const tasks = [

    { pid: 37 },

    { pid: 50 },

    { pid: 99 }

]

const offsets = tasks.map(t => pool.run('scan', { pid: t.pid, pattern: '00 ?? 00 ?? 07' }));

const results = await Promise.all(offsets)

// [-1]

```
