cp-file

What is cp-file?

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.

What are cp-file's main functionalities?

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');
});
