Introduction

1. The video is a Hindi tutorial focused on installing and setting up Angular 21.
2. It’s typically the first step before writing Angular applications — explaining tools and environment setup.

Prerequisites

Before installing Angular, you must have:

1. Node.js installed (latest stable version).
2. NPM (Node Package Manager) — automatically installed with Node.js.
3. 👉 These tools allow us to install the Angular CLI and run Angular apps locally.

. Installing Angular CLI

1. Use Terminal (macOS) or Command Prompt / PowerShell (Windows).
2. Run the core command:

This installs the Angular CLI globally so you can generate projects easily.

Creating a New Angular 21 Project

1. Generate a new Angular workspace using:

After running this:

1. You’ll be asked questions (e.g., whether to include routing).
2. Style format options might be shown (like CSS, SCSS).

Running the Angular App

1. Navigate to the project folder:

Start the Angular development server:

Visit the application directly in browser at:

1. This confirms that Angular is installed and working correctly. angular.io

macOS vs Windows Notes

Although steps are similar on both systems:

1. macOS uses the Terminal app.
2. Windows uses PowerShell or Command Prompt, but commands stay the same.

Common Errors & Fixes

Tutorials often cover:

1. Permission errors on macOS → use sudo if needed.
2. Firewall or PATH issues → ensuring Node and Angular CLI paths are correctly set.
3. (These are typical problems many learners face.)

Next Steps After Setup

Once setup is complete, a typical Angular 21 course continues with:

1. Understanding Angular folder structure.
2. Creating components (ng generate component <name>).
3. Learning modules, templates, data binding, and routing.
