Intro:
Express.js is the most popular framework for building REST APIs in Node.js.
Snippet:
const express = require("express");
const app = express();
app.use(express.json());
app.get("/api/hello", (req, res) => {
res.json({ message: "Hello World" });
});
app.listen(3000, () => console.log("Server running on http://localhost:3000"));Takeaway:
Keep routes modular and use express.json() for parsing JSON requests.
