rollup-plugin-copy2

library0.4.0jsnpmunverified

A Rollup plugin to copy additional assets to the build directory, version 0.4.0. Unlike typical copy plugins, it does not copy by default but emits files into the Rollup bundle, making them accessible to other plugins (e.g., rollup-plugin-zip). Actual copying is handled by Rollup itself. It supports glob patterns, source-destination pairs, and an optional outputDirectory for direct disk writes. Requires Rollup >=3.20.0. Minimalistic, ESM-only, with TypeScript support.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

copy

✓ import { copy } from 'rollup-plugin-copy2'

✗ import copy from 'rollup-plugin-copy2'

Named export, not default. ESM-only; no CommonJS support.

copy

✓ const { copy } = await import('rollup-plugin-copy2')

✗ const { copy } = require('rollup-plugin-copy2')

ESM dynamic import works, but require() fails because package is ESM-only.

CopyOptions

✓ import type { CopyOptions } from 'rollup-plugin-copy2'

TypeScript users can import the CopyOptions type for type safety.

Rollup configuration using copy plugin with glob, source-destination pair, and extra output directory.

// rollup.config.js import { copy } from 'rollup-plugin-copy2' export default { input: 'src/index.js', output: { dir: 'dist', format: 'es', }, plugins: [ copy({ assets: [ 'README.md', ['src/data.txt', 'assets/data.txt'], 'node_modules/some-lib/*.css', ], notEmitFiles: false, outputDirectory: 'additional', }), ], }

Debug

Known issues

gotchaFiles are not physically copied by default; they are emitted into Rollup's bundle. Use outputDirectory option to write them to disk.

fix

Set outputDirectory to a path if you need files on disk, or use another plugin like rollup-plugin-copy (note different package).

affects: >=0.1.0

gotchaGlob patterns only work when source is a single string, not in [source, dest] tuples. Tuples expect exact file paths.

fix

Use single string glob for multiple files; for renaming, use [exactPath, destPath].

affects: >=0.1.0

deprecatedThe plugin is ESM-only and does not support require(). Using require() will throw an error.

fix

Use import or dynamic import() in an ESM context. Set type: 'module' in package.json or use .mjs extension.

affects: >=0.1.0

gotchaFiles emitted by this plugin are not automatically included in the output unless downstream plugins handle them. If you only use copy without zip, you may see no output files.

fix

Either set outputDirectory to copy to disk, or add another plugin that consumes emitted assets (e.g., rollup-plugin-zip).

affects: >=0.1.0

Errors

Common errors & fixes

The requested module 'rollup-plugin-copy2' does not provide an export named 'default'

Attempting default import instead of named import.

fix

Change import copy from 'rollup-plugin-copy2' to import { copy } from 'rollup-plugin-copy2'.

Error: rollup-plugin-copy2 requires Rollup >=3.20.0

Installed rollup version is too old.

fix

Upgrade rollup to ^3.20.0 or later: npm install rollup@latest --save-dev.

TypeError: copy is not a function

Importing the wrong export (e.g., import * as copy from '...' then using copy()).

fix

Use named import: import { copy } from 'rollup-plugin-copy2'.
