Learn Qwik from A to Z (2025)

🚀 Why Are We Starting from Scratch?

In this "Learn Qwik from A to Z (2025)" series, we are rebuilding everything from zero. The goal is to guide absolute beginners — and those who want a clean and solid foundation — through each step required to set up a complete Qwik development environment.

Before diving into Qwik itself, it's essential to prepare your system properly. This starts with installing Node.js and npm, which are necessary to run Qwik and manage its dependencies smoothly and safely.

We won’t go into every advanced detail, but we’ll make sure you install everything the right way, so you can focus on learning and building real Qwik applications with confidence.

🎒 Prerequisites for Building a Qwik App

Before creating your first project, here's what you'll need:

• ✅ Ubuntu 22.04 LTS (or another recent version) 👉 Download Ubuntu
• ✅ Basic Terminal commands 👉 Open Terminal on Ubuntu (see our previous guide)
• ◇ Node.js v18.17 or higher (you are here)
• ◇ Visual Studio Code (or Cursor) 👉 Install Visual Studio Code on Ubuntu

📌 Open your Terminal

🔄 Update your package list

To make sure Ubuntu uses the most recent sources, update your package index:

🔐 Enter your password

Because you're using sudo, Ubuntu asks for your admin password. Type it and press Enter.

📦 Install curl (if not installed)

curl is required to fetch external scripts like the Node.js installer. Most systems have it by default:

🌐 Add the official Node.js setup script

This command comes from NodeSource’s GitHub page. It adds the latest LTS version (v18) to your system:

📥 Install Node.js (and npm)

After adding the repo, you can install both Node.js and npm in one go:

✅ Check Node.js version

To make sure Node.js is installed correctly:

✅ Check npm version

And finally, make sure npm is installed too:
