Deno for scripting

Deno for scripting

Foreword

It is largely inspired by kscript. The idea is to leverage the scripting abilities of javascript using Deno. I feel that scripting can be so much fun with Deno as:

  • It can import modules from any location on the web,
  • It is secure by default. Imported module can run in sandbox.
  • It is Supports TypeScript out of the box.
  • It is much more that Node

Deploy a fullstack js app on aws

Intro

There are many way to do it. Some of them are more efficient that others. Here are some paths to explore.

Fast and dirty: Every thing in on a EC2

  1. Create EC2 instance
  2. ssh in EC2
  3. Install everything (git, node, mongo)
  4. Open the inbound to the world
  5. Create a route53 and link it to you DNS
