Intro
So we installed NodeJS on our machine.
We also learned how to create a simple server using Node's HTTP module.
We also know How to Get External Packages.
Now we want to learn how to create a simple server using express.
Write a simple script
- Open your terminal
- Create a file named
index.js:
touch index.js
- Add this JavaScript code into it:
// import express (after npm install express)
const express = require("express");
// create new express app and save it as "app"
const app = express();
// server configuration
const PORT = 8080;
// create a route for the app
app.get("/", (req, res) => {
res.send("Hello World");
});
// make the server listen to requests
app.listen(PORT, () => {
console.log(`Server running at: http://localhost:${PORT}/`);
});
Note: This simple server has only one working route (/). If you want to learn more about Routing, read the docs for Routing.
Run it from the terminal
- Run it:
node index.js
- Result:
Server running at: http://localhost:8080/
Now you can click on the link and reach your created server.
