Learn Node.js

What you will practise

Move from browser JavaScript to server-side programming with Node.js. Practise modules, asynchronous tasks and API design.

• Split programs into modules.
• Read and transform data on the server.
• Build API routes and handle errors.

Before you start: You should be familiar with JavaScript variables, functions, arrays and promises.

A first example to understand

const response = { course: "Node.js", available: true };
console.log(JSON.stringify(response));

JSON.stringify turns the object into JSON text, a format commonly exchanged by an API and its client. No network server is needed for this conversion example.

Try it: Add a language property with the value JavaScript and inspect the resulting text.

Understand a specific concept

• Build a RESTful API with Node.js and Express (Production Architecture)
