What are Angular components? Angular components are the building blocks of Angular applications. They encapsulate the data, behavior, and template that define a part of the user interface. Components have their own logic and data, making them modular and reusable. Each component consists of a TypeScript class representing the component’s behavior, an HTML template defining the component’s view, and a CSS file for styling. 2. How do you create a component in Angular? To create a component in Angular, follow these steps: Use the Angular CLI command ‘ng generate component <component-name> to generate the component files. This command creates a folder with the specified component name and generates the component’s TypeScript, HTML, and CSS files. Open the TypeScript file and define the component’s logic and data in the class. Customize the HTML template to define the structure and layout of the component’s view. Add CSS styles to the component’s CSS file to apply custom styling. 3. What is the purpose of the ngOnInit() method in Angular? The ‘ngOnInit() method in Angular is a lifecycle hook that is called after Angular has initialized the component and set its input properties. It is used to perform initialization tasks such as retrieving data from a remote server, subscribing to observables, or initializing component-specific variables. This method is commonly used to set up the initial state of the component. Angular Directives 1. What are Angular directives? Angular directives are markers on a DOM element that instruct Angular to attach specific behaviors to that element or transform its structure. There are two types of directives in Angular: structural directives and attribute directives. 2. Explain the difference between structural and attribute directives. Structural directives in Angular, such as *ngIf and *ngFor, change the structure of the DOM by adding or removing elements based on certain conditions. They are denoted by the prefix * in the directive name and use the template syntax to manipulate the DOM structure. Attribute directives, on the other hand, modify the behavior or appearance of an existing element or component. They are applied as attributes on HTML elements and use the square bracket syntax, such as [ngClass] or [ngStyle]. Attribute directives can manipulate properties, add or remove classes, and handle events on the element they are applied to. Angular Services 1. What are Angular services? Angular services are singleton objects that provide specific functionality and can be shared across multiple components. They are used to centralize common data and logic that need to be accessed or shared by different parts of an application. Services can be used for data fetching, business logic, communication with APIs, and other application-wide tasks. 2. How do you create a … Read more
