**Oak** is a middleware framework for #key# Deno: A runtime for JavaScript and TypeScript. #key#’s HTTP server that includes a router middleware. It is the most popular choice for backend when it comes to building web applications with Deno.

> Oak is inspired by Koa. The middleware router is inspired by @koa/router.  

You can import oak in your Deno project using the direct URL:
```js
import {...} from " https://deno.land/x/oak@v4.0.0/mod.ts";
```

# Code

As an example, here's how a basic HTTP server with oak in Deno looks.  

import { Application } from " https://deno.land/x/oak@v4.0.0/mod.ts";

const app = new Application();

app.use((ctx) => {
  ctx.response.body = "Hello world!";
});

await app.listen("127.0.0.1:8000");



We import and create an `Application` class object. Middleware is added via the `.use()` method. The `.listen()` method will start the server and begin processing requests with the registered middleware.

You can run the code with Deno using the following command:
```shell
$ deno run --allow-net server.ts
```
