Copy a file

• 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.

$ npm install cp-file

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

(async () => {
	await cpFile('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.

Progress reporting. Only available when using the async method.

Type: Function

{
	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.

• 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 => {
		// …
	});
})();
