# deno-http-worker

[![NPM version](https://img.shields.io/npm/v/deno-http-worker.svg?style=flat)](https://npmjs.org/package/deno-http-worker)

Similarly to [deno-vm](https://github.com/casual-simulation/node-deno-vm), deno-http-worker lets you securely spawn Deno http servers.

## Usage

```ts

import { newDenoHTTPWorker } from 'deno-http-worker';

let worker = await newDenoHTTPWorker(

    `export default {

        async fetch(req: Request): Promise {

            return Response.json({ ok: req.url });

        },

    }`,

    { printOutput: true, runFlags: ["--allow-net"] }

);

const body = await new Promise((resolve, reject) => {

    const req = worker.request("https://hello/world?query=param", {}, (resp) => {

        const body = [];

        resp.on("error", reject);

        resp.on("data", (chunk) => {

            body.push(chunk);

        });

        resp.on("end", () => {

            resolve(Buffer.concat(body).toString());

        });

    })

    req.end();

})

console.log(body) // => {"ok":"https://hello/world?query=param"}

worker.terminate();

```

## Internals

Deno-http-worker connects to the Deno process over a Unix socket to make requests.  As a result, the worker does not provide an address or url, but instead returns `request` function that calls `http.request` under the hood, but modifies the request attributes to work over the socket.

If you need more advanced usage here, or run into bugs, please open an issue.
