fs-extra
fs-extra is a Node.js library that extends the built-in fs module by adding additional file system methods and making existing ones more convenient. It provides extra functionality like copying, moving, and removing files/directories recursively, as well as JSON file handling. The library aims to simplify common file operations in Node.js applications by offering promise-based APIs and enhanced error handling.
Developers should use fs-extra when building Node.js applications that require robust file system operations beyond what the native fs module offers, such as in build tools, CLI applications, or server-side scripts. It is particularly useful for tasks like copying entire directories, handling JSON files seamlessly, or performing recursive deletions, as it reduces boilerplate code and improves reliability with better error messages and promise support.
