rollup-plugin-copy-watch

0.0.1 verified Mon Apr 27 auth: no javascript

A fork of rollup-plugin-copy (v3.4.0) that adds a `watch` option to watch additional sources (e.g., static assets) outside Rollup's bundle graph, triggering copy on change. Version 0.0.1 is the only release (unstable). It uses Chokidar for file watching and supports glob patterns, multiple targets, and flatten/hash options. Less maintained than the original; use for watch-mode copy only, else prefer rollup-plugin-copy.

Common errors

error Error: Cannot find module 'chokidar' ↓

cause chokidar is not listed as a peer dependency and may not be installed automatically.

fix

Run npm install chokidar --save-dev.

error TypeError: copy is not a function ↓

cause Using named import { copy } instead of default import.

fix

Use import copy from 'rollup-plugin-copy-watch'.

Warnings

breaking The 'watch' option must be explicitly set to enable source file watching; default is null (no watch). ↓

fix Add `watch: 'your/path'` to the options object.

deprecated This package is a low-activity fork; prefer rollup-plugin-copy for production unless watch functionality is required. ↓

fix Switch to rollup-plugin-copy if watch is not needed.

gotcha Chokidar options are not exposed; only 'watch' is passed to chokidar.watch(). ↓

fix Use rollup-plugin-copy with a separate watcher if full Chokidar control is needed.

Quickstart

Rollup config that copies HTML and images with watch on static folder.

import copy from 'rollup-plugin-copy-watch';

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