Install Demo

brew install deno

Still Apple Spell checker invites me to change the spelling to demo.
I guess we all have to get used to it.

Trying the script

Installation is easy. Now I try with a simple typescript from deno.land

Trying out the script

import { serve } from "https://deno.land/std@0.50.0/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" });
}

deno run denoDemo.ts

That comes up with

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

oh 👌🏼...

deno run denoDemo.ts --allow-net

still

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

Now I have to turn myself into Google.com

it is actually and should be

> deno run --allow-net denoDemo.ts
http://localhost:8000/

Ta da well hello, world!
