Copy File

Simply copy a file. If an error occurs after the destination file has been opened for writing, copy-file will attempt to remove the destination. Correctly copies symlinks.

Install

npm i @cloudcmd/copy-file

API

copyFile(src, dest , streams)

src <string> - source filename to copy
dest <string>- destination filename of the copy operation
streams <array>- file processing streams (optional)

const copyFile = require('@cloudcmd/copy-file');

const ok = () => 'ok';
const error = (e) => e.message;

copyFile('./package.json', './package2.json')
    .then(ok)
    .catch(error)
    .then(console.log);

You can use preprocessing streams of copied file:

const copyFile = require('@cloudcmd/copy-file');

const zlib = require('zlib');
const gzip = zlib.createGzip();

const ok = () => 'ok';
const error = (e) => e.message;

copyFile('./package.json', './package2.json', [gzip])
    .then(ok)
    .catch(error)
    .then(console.log);

You can use copyFile with async-await:

const tryToCatch = require('try-to-catch');
const copyFile = require('@cloudcmd/copy-file');

(async () => {
    const [e] = await tryToCatch(copyFile, './package.json', './package2.json');
    
    if (!e)
        return;
    
    console.error(e.message);
})();
