Copy a file

Highlights

  • Fast by using streams in the async version and fs.copyFileSync() in the synchronous version.
  • Resilient by using graceful-fs.
  • User-friendly by creating non-existent destination directories for you.
  • Can be safe by turning off overwriting.
  • Preserves file mode, but not ownership.
  • User-friendly errors.

Install

$ npm install cp-file

Usage

const cpFile = require('cp-file');

(async () => {
	await cpFile('source/unicorn.png', 'destination/unicorn.png');
	console.log('File copied');
})();

API

cpFile(source, destination, options?)

Returns a Promise that resolves when the file is copied.

cpFile.sync(source, destination, options?)

source

Type: string

The file you want to copy.

destination

Type: string

Where you want the file copied.

options

Type: object

overwrite

Type: boolean
Default: true

Overwrite existing destination file.

cpFile.on('progress', handler)

Progress reporting. Only available when using the async method.

handler(data)

Type: Function

data
{
	sourcePath: string,
	destinationPath: string,
	size: number,
	writtenBytes: number,
	percent: number
}
  • source and destination are absolute paths.
  • size and writtenBytes are in bytes.
  • percent is a value between 0 and 1.
Notes
  • For empty files, the progress event is emitted only once.
  • The .on() method is available only right after the initial cpFile() call. So make sure you add a handler before .then():
const cpFile = require('cp-file');

(async () => {
	await cpFile(source, destination).on('progress', data => {
		// …
	});
})();
