Copy a file

cp-file

Copy a file

• Fast by using streams in the async version.
• Resilient by using graceful-fs.
• User-friendly by creating non-existent destination directories for you.
• Can be safe by turning off overwriting.
• User-friendly errors.

Install

$ npm install --save cp-file

Usage

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

cpFile('src/unicorn.png', 'dist/unicorn.png').then(() => {
    console.log('File copied');
});

API

cpFile(source, destination, [options])

Returns a Promise.

cpFile.sync(source, destination, [options])

source

Type: string

File you want to copy.

destination

Type: string

Where you want the file copied.

options

Type: Object

overwrite

Type: boolean
Default: true

Overwrite existing file.

cpFile.on('progress', handler)

Progress reporting. Only available when using the async method.

handler(data)

Type: Function

data

{
    src: String,
    dest: String,
    size: Number,
    written: Number,
    percent: Number
}

• src and dest are absolute paths.
• size and written 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():

cpFile(src, dest).on('progress', data => {
    // ...
}).then(() => {
    // ...
})
