Usage

// rollup.config.js
import copy from 'rollup-plugin-copy'

export default {
  input: 'src/index.js',
  output: {
    file: 'dist/app.js',
    format: 'cjs'
  },
  plugins: [
    copy({
      targets: [
        { src: 'src/index.html', dest: 'dist/public' },
        { src: ['assets/fonts/arial.woff', 'assets/fonts/arial.woff2'], dest: 'dist/public/fonts' },
        { src: 'assets/images/**/*', dest: 'dist/public/images' }
      ]
    })
  ]
}

Configuration

There are some useful options:

targets

Type: Array | Default: []

Array of targets to copy. A target is an object with properties:

• src (string Array): Path or glob of what to copy
• dest (string Array): One or more destinations where to copy
• rename (string Function): Change destination file or folder name
• transform (Function): Modify file contents

Each object should have src and dest properties, rename and transform are optional. globby is used inside, check it for glob pattern examples.

File

copy({
  targets: [{ src: 'src/index.html', dest: 'dist/public' }]
})

Folder

copy({
  targets: [{ src: 'assets/images', dest: 'dist/public' }]
})

Glob

copy({
  targets: [{ src: 'assets/*', dest: 'dist/public' }]
})

Glob: multiple items

copy({
  targets: [{ src: ['src/index.html', 'src/styles.css', 'assets/images'], dest: 'dist/public' }]
})

Glob: negated patterns

copy({
  targets: [{ src: ['assets/images/**/*', '!**/*.gif'], dest: 'dist/public/images' }]
})

Multiple targets

copy({
  targets: [
    { src: 'src/index.html', dest: 'dist/public' },
    { src: 'assets/images/**/*', dest: 'dist/public/images' }
  ]
})

Multiple destinations

copy({
  targets: [{ src: 'src/index.html', dest: ['dist/public', 'build/public'] }]
})

Rename with a string

copy({
  targets: [{ src: 'src/app.html', dest: 'dist/public', rename: 'index.html' }]
})

Rename with a function

copy({
  targets: [{
    src: 'assets/docs/*',
    dest: 'dist/public/docs',
    rename: (name, extension, fullPath) => `${name}-v1.${extension}`
  }]
})

Transform file contents

copy({
  targets: [{
    src: 'src/index.html',
    dest: 'dist/public',
    transform: (contents, filename) => contents.toString().replace('__SCRIPT__', 'app.js')
  }]
})

verbose

Type: boolean | Default: false

Output copied items to console.

copy({
  targets: [{ src: 'assets/*', dest: 'dist/public' }],
  verbose: true
})

hook

Type: string | Default: buildEnd

Rollup hook the plugin should use. By default, plugin runs when rollup has finished bundling, before bundle is written to disk.

copy({
  targets: [{ src: 'assets/*', dest: 'dist/public' }],
  hook: 'writeBundle'
})

copyOnce

Type: boolean | Default: false

Copy items once. Useful in watch mode.

copy({
  targets: [{ src: 'assets/*', dest: 'dist/public' }],
  copyOnce: true
})

flatten

Type: boolean | Default: true

Remove the directory structure of copied files.

copy({
  targets: [{ src: 'assets/**/*', dest: 'dist/public' }],
  flatten: false
})

All other options are passed to packages, used inside:

• globby
• fs-extra copy function
