Sending JSON responses is fundamental for building REST APIs and modern web applications with Node.js servers. As the creator of CoreUI, a widely used open-source UI library, I’ve built numerous backend APIs over 25 years of development experience. From my expertise, the most reliable approach is to use Express.js res.json() method, which automatically sets the correct content-type header and stringifies JavaScript objects. This ensures proper JSON formatting and client compatibility.

Making POST requests is essential for sending data to servers, submitting forms, creating resources, and interacting with APIs that modify server state. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented POST requests extensively for form submissions, user authentication, and data creation in admin panels. From my expertise, the fetch() API with POST method and JSON body is the modern standard for sending data to servers. This approach provides clean syntax, proper headers, and excellent error handling for reliable data transmission.

Making GET requests is fundamental for fetching data from APIs, loading external resources, and retrieving server-side information. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented countless GET requests for data fetching in dashboard components and dynamic content loading. From my expertise, the modern fetch() API is the best approach for making HTTP requests with its promise-based interface and built-in JSON parsing. This method is well-supported, clean, and provides excellent error handling capabilities.

Fetching data in React with Axios provides enhanced HTTP client features including request interceptors, automatic JSON parsing, and better error handling. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented Axios in countless React applications for complex API integrations and enterprise data management. From my expertise, the most effective approach is using Axios with useEffect hook for robust HTTP requests with built-in features. This method provides superior error handling, request configuration, and response transformation compared to native fetch.

Fetching data in React with the native fetch API enables HTTP requests for dynamic content loading without external dependencies. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented data fetching in thousands of React applications for dashboards, user profiles, and real-time data displays. From my expertise, the most effective approach is using useEffect hook with fetch API for clean data loading and error handling. This method provides built-in browser support with proper loading states and error management for robust applications.
