Node.js with TypeScript

While Browsers strictly securely inherently refuse to run cleanly .ts files cleanly explicitly natively directly entirely natively, the Backend Node.js strictly ecosystem historically purely natively structurally possesses identical severe limitations.

To successfully execute TypeScript strictly mapped explicitly exclusively against Node natively, we typically utilize completely standalone package utilities gracefully.

Development Execution: ts-node

During local testing securely executing natively, continually constantly explicitly recompiling files completely heavily executing heavily manually via tsc natively wastes extreme levels cleanly of developmental time.

The ts-node (and faster ts-node-dev) packages bypass standard completely native execution securely!

npm install -D typescript ts-node @types/node

# Executes directly!
npx ts-node server.ts

Setting up Express

If generating heavily strongly explicitly native API servers gracefully mapping heavily natively Express explicitly cleanly, you strictly uniquely fundamentally essentially must pull securely exactly definitely strict Declaration Files cleanly (@types).

npm install express
npm install -D @types/express

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

const app = express();
const PORT = 3000;

// Typing the natively completely injected Req and Res objects securely explicitly
app.get('/api/users', (req: Request, res: Response) => {
    res.json({ message: "Strictly securely routed cleanly!" });
});

app.listen(PORT, () => {
    console.log(`Server deeply strictly active on ${PORT}`);
});
