Read, write, update, and manage files without accidentally blocking your Node.js server.
Node.js provides the fs module for working with files and directories. You can read files, write new files, rename them, delete them, inspect metadata, and perform many other filesystem operations directly from your application.
Because file operations can take time, Node.js provides asynchronous APIs that allow your application to continue handling other work while the operating system performs the operation. Knowing when to use asynchronous, synchronous, or streaming APIs is important for building responsive servers.
