How to create a TypeScript project in Node.js
Big thanks to Jordan Irabor for his article "How To Set Up a Node Project With Typescript" that inspired me a lot for this.
#!/bin/bash
# this is because on my laptop:
# - there is the system 'node' (i.e. used by MS Team for Linux)
# - there is the 'node' I use for development work
export NODE_BIN="/home/mihamina/Apps/node/bin"
export PRJ="ts-project-01"
mkdir ${PRJ}
cd ${PRJ}
# We are inside the project directory, now
${NODE_BIN}/npm init -y
${NODE_BIN}/npm install --save typescript

import express from 'express';
const app = express();

app.get('/', (req, res) => {
res.send('Hello World!');
});
app.listen(port, () => {
return console.log('Express is listening at http://localhost:'+port);
});
