11 Essential Angular Concepts Every Developer Should Know

Discover the key concepts in Angular that every developer should know to build efficient, maintainable, and scalable applications.

  1. Component Basics: Components are the most basic UI building block of an Angular app. An Angular app contains a tree of Angular components. Angular components are a subset of directives, always associated with a template. Unlike other directives, only one component can be instantiated for a given element in a template.
  2. Data Binding: Angular data binding is a two-way process that can both send and receive data. This means that when you change something in your view, the model updates automatically, and vice versa.
  3. Dependency Injection: Dependency Injection, or DI, is a design pattern and mechanism for creating and delivering some parts of an application to other parts of an application that require them.
  4. Routing: Routing in Angular allows users to create a single-page application with multiple views and navigate between them seamlessly without losing the application state.
  5. Forms and Validation: Angular forms have built-in validators that validate user inputs. You can create custom validators to ensure the validity of user input before form submission.
  6. Pipes (Inbuilt and Custom): Pipes are simple functions to transform data in template expressions. They allow for reusable transformations across the application.
  7. Observables and RxJS: Observables provide support for asynchronous programming, event handling, and multiple value handling. RxJS is an implementation of Observables for JavaScript used widely in Angular applications.
  8. Services: Learn how services share data and functionality across components in Angular applications, making code more modular and reusable.
  9. Directives: Directives are classes that add behavior to elements in Angular applications. Angular provides built-in directives to manage forms, styles, and user interactions.
  10. Modules: Modules organize Angular apps and extend their capabilities. Libraries like FormsModule, HttpClientModule, and RouterModule are built using Angular modules.
  11. NgRx (State Management): State management allows developers to manage application state efficiently, making it easier to build large-scale applications with high performance.
