Clone the project

git clone --depth 1 --branch v1.0.1 git@github.com:wouerner/nodejs-typescript.git

docker-compose run app npm install -D @types/express 

install nodemon definitions:

docker-compose run app npm install -D nodemon

import express, {Request,Response,Application} from 'express';

const app:Application = express();

const PORT = process.env.PORT || 3000;

app.get("/", (req:Request, res:Response):void => {
  res.send("Hello Typescript with Node.js!")
});

app.listen(PORT, ():void => {
  console.log(`Server Running here 👉 https://localhost:${PORT}`);
});

add this to package.json:

nvim package.json

  "scripts": {
    "dev": "nodemon ./index.ts"
