Introduction2:21
Welcome to the course! Learn how this course will help you centralize API calls and handle errors effectively in your React projects using Axios and custom hooks.
Source Code1:04
In this lecture, you’ll get access to the complete source code for our centralized error-handling system in React. This includes a demo application, setup instructions, and a basic Node.js server to simulate API responses. Check out the detailed steps in the article below to clone the repo, install dependencies, configure environment variables, and run the project locally. If you have any questions or run into issues, feel free to ask in the Q&A. Happy coding!

Introducing the Initial Naive Scenario1:41
Discover the simplest way to make an API call in React and explore why this naive approach falls short in handling real-world scenarios.
Adding Error Scenario and Basic Error Handling1:53
Simulate error scenarios and implement basic error handling using try-catch blocks to manage unexpected issues in your React components.
Introducing Loading and Error States Inline3:04
Enhance user experience by adding loading and error states inline, ensuring users are informed when data is loading or when errors occur.
Highlighting the Pain Points1:22
Understand the limitations of inline error handling and why a centralized approach is essential for scaling React applications.
Centralizing Axios with a Custom Instance5:39
Learn to create a centralized Axios instance for consistent API configurations, reusable logic, and simplified maintenance across your React app.
Introducing Service Modules6:49
Organize your API logic into service modules to separate concerns, reduce repetition, and make your codebase cleaner and more modular.
Bonus Reading: Understanding Promises and Rejections in JavaScript2:02
A quick overview of Promises in JavaScript.
Adding Axios Interceptors11:37
Set up Axios interceptors for global error handling, custom error messages, and consistent request/response management in your application.
Implementing the useApi Hook16:09
Build a reusable useApi hook to centralize API state management, including data, loading, and error states, for cleaner React components.
Connecting Dots3:24
Visualize how all the pieces—Axios instance, service modules, interceptors, and useApi—work together to create a scalable error-handling system.
Course wrap up2:05
Recap key takeaways from the course, explore advanced topics to continue your learning journey, and celebrate your achievement!

Requirements

Basic Knowledge of React: Familiarity with React components, state, and hooks (e.g., useState and useEffect)
JavaScript Fundamentals: Understanding of ES6+ syntax, including promises, async/await, and destructuring
Development Environment Setup: A code editor like VS Code installed on your computer and a basic React project ready to work on
No advanced React knowledge is required—this course is designed to be beginner-friendly while providing value for intermediate developers

Description

Are you tired of writing repetitive try-catch blocks or struggling with messy error-handling code in your React projects?

This free course is your step-by-step guide to building a centralized error-handling system using Axios, custom hooks, and service modules.
