Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cpy) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cpy

Copy files

Why

Fast by using streams.
Resilient by using graceful-fs.
User-friendly by accepting globs and creating non-existent destination directories.
User-friendly error messages.
Progress reporting.

Install

$ npm install cpy

Usage

const cpy = require('cpy');

(async () => {
    await cpy(['source/*.png', '!source/goat.png'], 'destination');
    console.log('Files copied!');
})();

API

cpy(source, destination, options?)

Returns a Promise<string[]> with the destination file paths.

source

Type: string | string[]

Files to copy.

If any of the files do not exist, an error will be thrown (does not apply to globs).

destination

Type: string

Destination directory.

options

Type: object

Options are passed to globby.

In addition, you can specify the below options.

cwd

Type: string
Default: process.cwd()

Working directory to find source files.

overwrite

Type: boolean
Default: true

Overwrite existing files.

parents

Type: boolean
Default: false

Preserve path structure.

rename

Type: string | Function

Filename or function returning a filename used to rename every file in source.

const cpy = require('cpy');

(async () => {
    await cpy('foo.js', 'destination', {
        rename: basename => `prefix-${basename}`
    });
})();

concurrency

Type: number
Default: (os.cpus().length || 1) * 2

Number of files being copied concurrently.

ignoreJunk

Type: boolean
Default: true

Ignores junk files.

Progress reporting

cpy.on('progress', handler)

handler(progress)

Type: Function

progress

{
    completedFiles: number,
    totalFiles: number,
    completedSize: number,
    percent: number
}

completedSize is in bytes
percent is a value between 0 and 1

Note that the .on() method is available only right after the initial cpy call, so make sure you add a handler before awaiting the promise:

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