Deno is a secure runtime for JavaScript and TypeScript.

Deno is basically Node reversed.

We will install Deno on Ubuntu.

Enter the following commands in Terminal.

sudo apt install curl # do this if you don't have curl already installed
Code language: PHP (php)
curl -fsSL https://deno.land/x/install/install.sh | sh
Code language: JavaScript (javascript)

Next step is specifying Deno’s path to bash.

Open .bashrc and add the lines below to it.

nano ~/.bashrc
export DENO_INSTALL="/home/$USER/.deno" export PATH="$DENO_INSTALL/bin:$PATH"
Code language: JavaScript (javascript)

Open a new Terminal instance.

Enter the following command.

deno

To check the version on Deno simply run.

deno -v

Run the following command.

deno run https://deno.land/std/examples/welcome.ts
Code language: JavaScript (javascript)

You can also write your first Deno hello world server, sample code below.

import { serve } from "https://deno.land/std@0.59.0/http/server.ts"; const s = serve({ port: 8000 }); console.log("http://localhost:8000/"); for await (const req of s) { req.respond({ body: "Hello World\n" }); }
