API reference

1. cp & cpSync

copy files to new path

• Usage: cp(path, target[, options]) & cpSync(path, target[, options])

• Types:

interface CpOptions extends RmDirOptions {
  force?: boolean
  silent?: boolean
}

declare function cp(

1. copy ./a to ./b

import { cp, cpSync } from '@node-kit/extra.fs'

cp('./a', './b').then(() => {
  console.log('copy done')
