How to create new angular app

To create a new Angular app, you can use the Angular CLI (Command-Line Interface). Here are the steps:

Prerequisites:

• Node.js installed on your machine (version 14 or higher)
• npm (Node Package Manager) installed on your machine
• A code editor or IDE of your choice

Step 1: Install the Angular CLI

Open a terminal or command prompt and run the following command:

npm install -g @angular/cli

This will install the Angular CLI globally on your machine.

Step 2: Create a new Angular app

Run the following command to create a new Angular app:

ng new my-app

Replace my-app with the name of your app.

Step 3: Choose the app template

The Angular CLI will prompt you to choose a template for your app. You can choose from the following options:

• blank: A blank app with no pre-built features
• routing: An app with routing enabled
• service-worker: An app with a service worker enabled
• pwa: A Progressive Web App (PWA) with routing and service worker enabled

Choose the template that best fits your needs.

Step 4: Configure the app

The Angular CLI will ask you to configure your app. You can choose the following options:

• Language: Choose the programming language for your app (e.g., TypeScript, JavaScript)
• Style: Choose the CSS preprocessor for your app (e.g., Sass, Less)
• Prefix: Choose the prefix for your app's CSS classes (e.g., app-, my-app-)

Choose the options that best fit your needs.

Step 5: Create the app

Once you've configured your app, the Angular CLI will create the app structure and install the necessary dependencies.

Step 6: Start the app

Run the following command to start the app:

ng serve

This will start the app in development mode, and you can access it by navigating to http://localhost:4200 in your web browser.

Step 7: Build and deploy the app

Once you've developed your app, you can build it using the following command:

ng build

This will create a production-ready build of your app. You can then deploy the app to a production environment using your preferred deployment method (e.g., hosting on a server, deploying to a cloud platform).

That's it! You've created a new Angular app using the Angular CLI.
