10 Common Mistakes in MERN Development

In MERN development, several common mistakes can hinder project success. Ignoring state management leads to tangled code, while hardcoding sensitive data poses security risks. Overlooking error handling and component reusability complicates debugging and maintenance. Performance optimization is often neglected, impacting user experience. Misconfiguring CORS can block essential requests, and skipping version control risks collaboration issues. Failing to write tests leaves code vulnerable to bugs, while not prioritizing responsive design alienates users on mobile devices. Lastly, poor API design can confuse developers and users alike. Addressing these pitfalls is crucial for building robust MERN applications.
