Note to self: You started using Replit instead: https://replit.com/@JanacMeena/Janacs-Typescript, since it was simpler to run the code. However, it might be worthwhile figuring out how to setup a simple test repo offline, so I can use github copilot.

Typescript Experiments

This repo tracks my progress with learning Typescript, and related technologies, including:

Stack

• Typescript
  • Date library
• Jest tests
• NodeJS
• Built in WebStorm

Frontend

• React Router
• Typescript Open API Standard - TOAS

Backend

• TSyringe - DI Framework
• ExpressJS
• Yarn
• Nodemon

My Review of this Stack

I started this repo May 11th 2021. Since then, NextJS has exploded in popularity, and ExpressJS is decreasing in popularity. I plan on continuing my experiments in a new repo: https://github.com/janacm/nextjs/

Setup

• Install ts-node

# Locally in your project.
npm install -D typescript
npm install -D ts-node

# Or globally with TypeScript.
npm install -g typescript
npm install -g ts-node

   • This will compile and output the Typescript files as JS into ./out.
2. Run node out/app.js
   • This starts the application
