Core Concepts of Angular

• Component: The core building unit of an Angular application's UI, consisting of a view (template), logic (class), and styling.
• Directive: Sets of instructions that enhance the functionality of an HTML element by manipulating the DOM based on specifications.
• Module: A unified block of code that organizes components, directives, pipelines, and services.
• Routing: Routing is the system that governs how the program responds to various URL pathways, deciding which component to display.
• Class: A class is a blueprint for building objects with properties (data) and methods (actions).
• Pipe: A function that modifies data before rendering it in an Angular template.
• Service: A reusable class that provides business logic and data access capability to components.
• Enum: A collection of named constant values that represent a fixed set of possibilities, improving code readability.

Features of Angular

The Features of Angular are explained as follows:

• Cross-Platform: Angular applications may be deployed across multiple platforms, including the web, mobile native apps, and desktop apps.
• Improved Dependency Injection: Dependency injection is a mechanism for introducing dependencies into a component or service. Angular simplifies dependency injection, making it easier to develop maintainable code.
• Improved Data Binding: Angular employs two-way data binding, which automatically synchronizes model data with the view. This makes development easier and eliminates the need to write a lot of boilerplate code.
• Improved Browser Support: Angular is compatible with the most recent versions of Chrome, Firefox, Safari, Edge, and Internet Explorer 11.
• Mobile Development: Angular may be used to create cross-platform mobile applications with frameworks such as Ionic.
• TypeScript: Angular apps are written in TypeScript, a superset of JavaScript with optional static typing. TypeScript helps to detect mistakes early in the development process and makes code more maintainable.
• Routing: Routing is the method for switching between views in an Angular application. Angular includes a built-in router that makes it simple to design routes and manage navigation events.
• Directives: Directives are DOM element markers that change the behavior of the DOM or a component. Angular includes several pre-built directives, as well as the ability to construct your own.

Configuration to get started with Angular

If we want to get started with Angular for the upcoming projects, there are some prerequisites that we need to follow are described below.

Need to have nodejs latest or stable version

To get started with Angular, we must have Nodejs to be installed on our machine, and we can get the latest one from here. We can choose one from the different supported operating systems and can continue with the setup process. Aspiring to master Angular through dedicated learning? Exploring Angular JS training can provide the necessary skills and guidance for a comprehensive understanding of this framework.

Installing the Angular CLI

After installing the nodejs, now we have NPM (Node Package Manager) which allows us to grab useful packages from the global registry. To use the CLI command, we need to install CLI using the below command.

npm install –g @angular/cli

Creating the Angular app

When we did the installation of CLI, now it’s time to create the new Angular app, for that we can use the below command.

 ng new <app_name>

Executing the Angular app

So far, we have created an angular app using the CLI command, now after creating the app, let's execute it and see what it looks like. For that, we can go to the project directory and use the below command.

ng serve –open

The additional option –open will open a blank window of a browser along with the default port number. This is how we can install the required software and start our Angular app development journey.
