Drash

A REST microframework for Deno with zero dependencies.

// File: app.ts

import { Drash } from "https://deno.land/x/drash@v1.0.0-rc1/mod.ts";

class HomeResource extends Drash.Http.Resource {
  static paths = ["/"];
  public GET() {
    this.response.body = "Hello World! deno + Drash is cool!";
    return this.response;
  }
}

const server = new Drash.Http.Server({
  response_output: "text/html",
  resources: [HomeResource]
});

server.run({
  hostname: "localhost",
  port: 1447
});

console.log("Server listening: http://localhost:1447");

$ deno --allow-net app.ts
Server listening: http://localhost:1447

$ curl localhost:1337
Hello World! deno + Drash is cool!

Why Use Drash?

Drash is designed to help you build your projects quickly with the ability to scale. You can build an API, a web app, an SPA (like the documentation pages), or even a static HTML site. How you use Drash is up to you, so it can be everything you need and nothing you don’t — like a DRASH tent.

Drash takes concepts from the following:

• Flask — being micro and extensible
• Laravel — use of similarly styled middleware
• Tonic — use of resources
• RESTful principles — content negotiation, HTTP verbs, URIs, etc.

Thrown into the mix is Drash’s own concepts such as:

• Documentation-driven development
• Test-driven development
• Lowering barriers to usage

Drash does not force you to use all of its code. You can pick and choose which data members you want/need and use them however you deem fit. For example, Drash comes with a console logger and a file logger. If you only want these, then you only import these into your non-Drash project. How you use it is really up to you.

Example Drash App

The example_app directory contains an example Drash application. You can run it using deno locally.

1. Install deno.

curl -fsSL https://deno.land/x/install/install.sh | sh -s v1.0.0-rc1

1. Run the Drash application using deno.

deno --allow-net --allow-env https://deno.land/x/drash@v1.0.0-rc1/example_app/app.ts

1. Make the following request: GET /.

curl --request GET localhost:1447

"GET request received!"

1. Make the following request GET /coffee/17.

curl --request GET localhost:1447/coffee/17

{"name":"Light"}

1. Make the following request POST /.

curl --request POST localhost:1447

"POST request received!"

1. Make the following request PATCH / (with verbose flag). This method is not defined in the HomeResource class, so you should receive a 405 response.

curl --request PATCH --verbose localhost:1447

*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 1447 (#0)
> PATCH / HTTP/1.1
> Host: localhost:1447
> User-Agent: curl/7.64.1
