Code

Verified usage

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

default

✓ import copy from 'rollup-plugin-cpy'

✗ const { default: copy } = require('rollup-plugin-cpy')

Default export; ESM-only. CommonJS require must use .default.

copy

✓ import copy from 'rollup-plugin-cpy'

✗ import { copy } from 'rollup-plugin-cpy'

Named import does not exist; use default import.

ConfigArray

✓ // Config is an array of objects or a single object // No TypeScript types are provided in this version. // Use JSDoc or infer from usage.

✗ import { Config } from 'rollup-plugin-cpy'

TypeScript types not exported; manually type the config as { files: string | string[], dest: string, options?: { verbose?: boolean, cwd?: string, ... } }

Copies all files from src/static to dist/static, excluding exclude.txt.

// Install: npm i -D rollup-plugin-cpy // rollup.config.js import copy from 'rollup-plugin-cpy'; export default { input: 'src/index.js', output: { dir: 'dist', format: 'cjs' }, plugins: [ copy({ files: ['src/static/**/*', '!src/static/exclude.txt'], dest: 'dist/static', options: { verbose: true } }) ] };

Debug

Known issues

gotchaFiles are copied after the bundle is written, so they may overwrite output files if dest overlaps.

fix

Ensure dest directory does not overlap with output dir, or use copy as last plugin.

affects: >=1.0.0

gotchaThe cpy library uses CJS; rollup-plugin-cpy is ESM only, requiring Rollup to handle dependencies.

fix

Make sure Rollup is configured to handle CJS dependencies (e.g., with @rollup/plugin-commonjs).

affects: >=2.0.0

deprecatedThe cpy package v9+ changed API; this plugin uses cpy v8 internally, causing potential incompatibility if cpy is updated globally.

fix

Pin cpy to v8 in your package.json if issues arise.

affects: >=2.0.0

breakingVersion 2.0.0 dropped support for Node.js < 8 and Rollup < 1.

fix

Upgrade Node to >=8 and Rollup to >=1.

affects: >=2.0.0

gotchaGlob patterns in files should use forward slashes (/) even on Windows.

fix

Use path.posix.join or manually convert backslashes.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'cpy'

cpy is a peer dependency not installed automatically.

fix

Run 'npm install cpy' or add cpy to your devDependencies.

TypeError: (0 , _rollupPluginCpy.default) is not a function

CommonJS require without accessing .default

fix

Use: const copy = require('rollup-plugin-cpy').default;

Error: Unexpected token: punc (.)

Using ES module syntax without transpilation in Node < 9 or without type: 'module'.

fix

Use require() or transpile with Babel/TypeScript.

ERR_PACKAGE_PATH_NOT_EXPORTED: Package subpath './package.json' is not defined

Old Node versions may not resolve package exports properly.

fix

Upgrade Node to >=12 or remove exports from package.json manually.
