17 common Node.js errors and how to solve them

Node.js, a powerful tool for building scalable web services, is prone to various developer mistakes that can lead to common errors, such as unhandled exceptions in streams, memory leaks, and environment compatibility issues. Streams are essential for reading and writing asynchronous data, but without proper error handling, they can crash applications. Memory leaks, often caused by unclosed connections, undisposed objects, and circular references, lead to the JavaScript heap out of memory error. Environment compatibility errors, like ReferenceError for document or window, arise when browser-specific code is run in Node.js. Network errors such as ECONNRESET and ECONNREFUSED indicate connectivity issues, while errors like EADDRINUSE signify port conflicts. Addressing these problems involves using error handlers, managing memory effectively, ensuring environment-specific code execution, and resolving network issues. Understanding these errors enhances the developer's grasp of Node.js, leading to more reliable applications.
