How to destroy node.js in 60 seconds with deno.js

Hello guys, Noobie programmer here!!!

Today I will teach you how to destroy node.js in 60 seconds with deno.js which is another Javascript runtime (though you can use Typescript in it. And also, a little trivia before we start: DENO is short fo DEstroy NOde hence the name.

Install Deno

First and foremost let's go to the website of the deno.js: https://deno.land/ . We need to install deno first and it's written in the website see the code below.

For mac/ubuntu users: 

curl -fsSL https://deno.land/x/install/install.sh | sh

For window users:

• open a powershell and type the code below:

iwr https://deno.land/x/install/install.ps1 -useb | iex

Destroy node

Let's start by running this one line of code:

deno run https://deno.land/std/examples/welcome.ts

As you can see with deno we can run scripts saved on a remote location and this is a very big plus since we don't need to clone the whole repo just to try and run the code. This is very convenient for us developers.

Let's create a new file named server.js and copy these few lines of codes to get started. As you can see each deno project is now lightweight and doesn't contain node_modules, and this gives developers convenient in some ways.

import { serve } from "https://deno.land/std@0.55.0/http/server.ts"; 

const s = serve({ port: 8000 }); 

console.log("http://localhost:8000/"); 

for await (const req of s) { 

    req.respond({ body: "Hello Deno and goodbye nodejs" }); 

}

One last step, we need to run the code and since deno is secured we need to use the -allow-net flag 

deno run --allow-net server.js

otherwise an error like this will popup:

error: Uncaught PermissionDenied: network access to "0.0.0.0:8000", run again with the --allow-net flag

You can find the source code here: https://github.com/doppelgunner/How-to-Destroy-Nodejs-in-60-seconds-with-Deno

If you want you can run the script from the repo with the command:

deno run --allow-net https://raw.githubusercontent.com/doppelgunner/How-to-Destroy-Nodejs-in-60-seconds-with-Deno/master/server.js

Voila!!!  we just destroy node and it's node_modules. Brag these to your noobie friends out there.
