Supply Chain Attack Detected in Solana's web3.js Library
A supply chain attack has been detected in versions 1.95.6 and 1.95.7 of the popular @solana/web3.js library.
The cp-file npm package is a utility for copying files with support for progress reporting and other advanced features. It is designed to be a simple and efficient way to copy files in Node.js applications.
Basic File Copy
This feature allows you to copy a file from a source path to a destination path. The promise resolves when the file has been successfully copied.
const cpFile = require('cp-file');
cpFile('source.txt', 'destination.txt').then(() => {
console.log('File copied');
});
Progress Reporting
This feature provides progress reporting during the file copy process. You can listen to the 'progress' event to get updates on the copy progress.
const cpFile = require('cp-file');
cpFile('source.txt', 'destination.txt').on('progress', data => {
console.log(`Progress: ${data.percent * 100}%`);
}).then(() => {
console.log('File copied');
});
Preserve Timestamps
This feature allows you to preserve the original file timestamps when copying a file. This can be useful for maintaining file metadata.
const cpFile = require('cp-file');
cpFile('source.txt', 'destination.txt', { preserveTimestamps: true }).then(() => {
console.log('File copied with timestamps preserved');
});
Overwrite Option
This feature allows you to specify whether to overwrite the destination file if it already exists. By setting the 'overwrite' option to false, you can prevent accidental overwrites.
const cpFile = require('cp-file');
cpFile('source.txt', 'destination.txt', { overwrite: false }).then(() => {
console.log('File copied without overwriting existing files');
}).catch(error => {
console.error('File already exists');
});
fs-extra is a popular package that extends the native Node.js fs module with additional methods, including file copying. It provides similar functionality to cp-file but also includes many other file system utilities, making it a more comprehensive solution.
ncp (Node Copy) is another package for copying files and directories. It offers similar functionality to cp-file but is more focused on copying entire directories, making it a good choice for more complex copy operations.
cpy is a package for copying files with a focus on simplicity and performance. It offers similar features to cp-file, such as progress reporting and the ability to preserve timestamps, but is designed to be more lightweight and efficient.
Copy a file
fs.copyFileSync()
in the synchronous version.npm install cp-file
import {copyFile} from 'cp-file';
await copyFile('source/unicorn.png', 'destination/unicorn.png');
console.log('File copied');
Returns a Promise
that resolves when the file is copied.
Type: string
The file you want to copy.
Type: string
Where you want the file copied.
Type: object
Type: boolean
Default: true
Overwrite existing destination file.
Type: string
Default: process.cwd()
The working directory to find source files.
The source and destination path are relative to this.
Type: number
Default: 0o777
Permissions for created directories.
It has no effect on Windows.
Type: (progress: ProgressData) => void
The given function is called whenever there is measurable progress.
Only available when using the async method.
ProgressData
{
sourcePath: string,
destinationPath: string,
size: number,
writtenBytes: number,
percent: number
}
sourcePath
and destinationPath
are absolute paths.size
and writtenBytes
are in bytes.percent
is a value between 0
and 1
.onProgress
callback function is emitted only once.import {copyFile} from 'cp-file';
await copyFile(source, destination, {
onProgress: progress => {
// …
}
});
