cpy

Forked from sindresorhus/cpy and add security patch for CVE-2020-28469.

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 @brickdoc/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.

filter

Type: Function

Function to filter files to copy.

Receives a source file object as the first argument.

Return true to include, false to exclude. You can also return a Promise that resolves to true or false.

const cpy = require("cpy");

(async () => {
    await cpy("foo", "destination", {
        filter: (file) => file.extension !== "nocopy",
    });
})();

Source file object

path

Type: string
Example: '/tmp/dir/foo.js'

Resolved path to the file.

relativePath

Type: string
Example: 'dir/foo.js' if cwd was '/tmp'

Relative path to the file from cwd.

name

Type: string
Example: 'foo.js'

Filename with extension.

nameWithoutExtension

Type: string
Example: 'foo'

Filename without extension.

extension

Type: string
Example: 'js'

File extension.

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) => {
        // …
    });
})();
