🚀 How to Install Angular 20 Step-by-Step for Beginners

Angular 20 is here — faster, more efficient, and modern. Whether you’re a beginner or upgrading, this guide walks you through installing Angular 20 from scratch.

✅ Prerequisites

Before starting, ensure your system has:

• Node.js (version 18 or later)
• npm (comes with Node.js)
• A terminal or command prompt

Check your Node version with:

node -v

Download Node from the official Node.js site if it’s not installed.

🛠️ Step 1: Install Angular CLI (v20)

Angular CLI is a command-line tool to create and manage Angular apps. Use the command below to install it globally:

npm install -g @angular/cli@20

Verify installation with:

ng version

You should see:

Angular CLI: 20.x.x
Node: 18.x.x

🏗️ Step 2: Create a New Angular 20 Project

Use this command to scaffold a new Angular app:

ng new my-angular-app

You’ll be prompted to:

• Enable Angular routing (Yes/No)
• Select a stylesheet format (CSS, SCSS, etc.)

📂 Step 3: Navigate into the Project

Change directory to your project folder:

cd my-angular-app

🚀 Step 4: Serve the Application

Start the development server:

ng serve

Open your browser and go to:

http://localhost:4200

🎉 You should see the default Angular welcome page!

✨ Step 5 (Optional): Use Standalone API

Angular 20 supports standalone component-based apps. Use the following command for a module-less setup:

ng new my-standalone-app --standalone
