Description

Introduction: Integrating Angular with RESTful APIs

Welcome to “Integrating Angular with RESTful APIs”! This training is designed to teach you how to effectively connect Angular applications with RESTful APIs, enabling you to build dynamic and data-driven web applications. You will learn how to make HTTP requests, handle responses, and integrate data into your Angular components. By the end of this course, you’ll be able to seamlessly connect your Angular application to various backend services and APIs.

Prerequisites for Integrating Angular with RESTful APIs

Before starting this training, you should have:

1. Basic knowledge of Angular (e.g., components, modules, services).
2. Familiarity with TypeScript and basic programming concepts.
3. Understanding of RESTful API principles and HTTP methods.

  • Transforming and combining data streams

6: Implementing Authentication with APIs

• Handling Authentication:
  • Implementing token-based authentication (e.g., JWT)
  • Managing authentication tokens and session data
• Securing API Calls:
  • Adding authentication headers to requests
  • Handling protected routes and API endpoints

7: Working with RESTful API Data in Angular Components

• Binding Data to Components:
  • Displaying API data in Angular components
  • Using Angular’s data binding features to update the UI
• Managing State and Data Flow:
  • Strategies for managing and caching data in components
  • Using services to share data between components

8: Advanced API Integration Techniques

• Handling Pagination and Infinite Scrolling:
  • Implementing pagination for large datasets
  • Adding infinite scrolling features to your application
• Optimizing API Calls:
  • Debouncing and throttling API requests
  • Using Angular’s Http Interceptor to optimize requests

9: Testing API Integration

• Unit Testing Services:
  • Writing unit tests for Angular services that interact with APIs
  • Mocking HTTP requests using Http Client Testing Module
• End-to-End Testing:
  • Testing API integration with end-to-end tests
  • Using tools like Protractor or Cypress for API testing

10: Conclusion and Next Steps
