fs module, which provides an API for interacting with the file system, is essential for this operation.
fs module includes the
fs.rename() method used to asynchronously rename a file at the path specified.
Synchronous file renaming
For synchronous renaming, use
fs.renameSync() method. It blocks the Node.js event loop until the file is renamed.
Renaming with promises
Node.js also allows you to use promises with the
fs.promises API for a cleaner asynchronous code structure.
It is crucial to handle errors effectively to avoid crashing your application. Use try/catch blocks for synchronous code, and for asynchronous code, make sure to handle promise rejections.
fs with async/await
For a modern approach, integrating
async/await syntax with
fs.promises can lead to more readable code.
File renaming in a web browser
If you need to rename a file within a web browser context, for example when dealing with files in an
input element, you can't directly rename the file, but you can create a new
File object with the desired name.
By following these patterns, you can effectively rename files in a Node.js environment or manipulate file references in a web browser context.
