Angular is a popular JavaScript framework for building single-page web applications. Here are some core concepts that are essential to understand when working with Angular.

Directives

Directives are a fundamental building block of Angular components. They are responsible for transforming the DOM and binding data to the template.

  • Attribute Directives: Apply to elements and attributes.
  • Structural Directives: Modify the structure of the DOM.
  • Input/Output Properties: Allow two-way data binding.

Components

Components are the smallest reusable parts of an Angular application. They encapsulate the logic and UI for a specific functionality.

  • Component Structure: Templates, styles, and TypeScript code.
  • Component Lifecycle Hooks: Lifecycle methods that run at different stages of a component's life.

Services

Services are used to manage shared logic and data across components. They can be injected into components to provide functionality.

  • Creating a Service: Use the @Injectable() decorator.
  • Dependency Injection: A key feature of Angular that simplifies service usage.

Forms

Angular provides a powerful and flexible form handling system.

  • Template-driven Forms: Use HTML form controls and event handling.
  • Reactive Forms: Use TypeScript to define forms and handle data.

Routing

Routing allows you to navigate between different views in your application.

  • Angular Router: The core module for routing.
  • Route Configuration: Define routes and resolve data.

Dependency Injection

Dependency Injection (DI) is a key feature of Angular that simplifies component design and testing.

  • Provider: A factory that returns an instance of a service.
  • Injection Tokens: Used to identify dependencies.

Performance Optimization

Optimizing your Angular application can improve its performance and user experience.

  • Change Detection: Angular's mechanism for updating the DOM.
  • Lazy Loading: Load modules only when needed.
