• ✨ Release Notes

Features

• 🛡️ Wraps node:fs, node:fs/promises, and fs-extra functions with try-catch for error prevention
• ✔️ Returns true on success and false on failure for functions that originally return void
• 📊 Returns data on success and undefined on failure for functions that originally return data
• 🌐 Provides support for most node:fs, node:fs/promises, and fs-extra functions
• 🔧 Additional utility functions for file and path operations

Environmental Requirements

• Node.js version 18 or higher

Installation

Add dependency (example using pnpm).

pnpm add @kikiutils/fs-extra

You can also use yarn, npm, or bun to add the dependency.

That's it! You're ready to use this package in your project. Check out the usage instructions below ✨.

Usage

When using node:fs, node:fs/promises, or fs-extra functions, you may only care about whether the operation succeeds, not the reason for any errors.

This package wraps these functions with try-catch to prevent errors from stopping the entire program.

Functions that originally return void now return true on success and false on failure.

Functions that originally return data now return the data on success and undefined on failure.

[!IMPORTANT] If the function you are executing does not have a corresponding feature in the runtime, it will throw a ToWrapFunctionIsUndefinedError error.

import kFse, { rename } from '@kikiutils/fs-extra';

const data = await kFse.readJson(path);
// Any json data - successfully read
// undefined - an error occurred

const result = await rename(oldPath, newPath);
// true - successfully renamed
// false - an error occurred

See the description below to find out which functions are available.

Available Functions

You can use most of the functions provided by node:fs, node:fs/promises, and fs-extra, but all functions that do not end with "Sync" will return a Promise.

All functions do not have a callback parameter because errors are passed to the callback if used.

If you need to use the callback functionality, please import and use the functions directly from the original package.

• node:fs-promises-api
• node:fs-synchronous-api
• fs-extra

Additional Functions

The following functions have corresponding sync versions.

• getFileSize - Uses stat to get the file size.
• pathIsBlockDevice - Uses stat to check if a path is a block device.
• pathIsCharacterDevice - Uses stat to check if a path is a character device.
• pathIsDirectory, pathIsDir - Uses stat to check if a path is a directory.
• pathIsFIFO - Uses stat to check if a path is a FIFO (named pipe).
• pathIsFile - Uses stat to check if a path is a file.
• pathIsSocket - Uses stat to check if a path is a socket.
• pathIsSymbolicLink - Uses stat to check if a path is a symbolic link.
• readFileToBlob - Reads a file and returns its contents as a Blob.

Unexported Functions

Deprecated functions are not exported.

The following functions do not need to be wrapped with try-catch. If you need to use them, please import them directly from node:fs or node:fs/promises:

• fs.watch
• fs.watchFile
• fs.promise.watch
