Standardised error and response from server in MERN

In this video tutorial by Hitesh, part of a comprehensive backend series, we explore the importance of standardizing error and response handling in MERN stack applications. This practice, commonly seen in professional codebases, is often overlooked but essential for maintaining clean and efficient code. Hitesh introduces the concept of creating helper utilities, such as an asynchronous handler (async Handler), which simplifies error management across various HTTP requests by wrapping them in try-catch blocks. This ensures that errors are handled gracefully without redundant code. Additionally, he discusses standardizing API responses using custom classes like APIResponse and APIError, making sure that every response sent to the frontend is consistent and informative. These practices, although optional, are crucial for building scalable and maintainable applications. The video provides step-by-step instructions on implementing these utilities, helping developers understand the significance of higher-order functions, error handling, and response standardization in Node.js and Express environments. Whether you're a beginner or a seasoned developer, adopting these best practices will elevate the quality of your codebase.
