@guanghechen/rollup-plugin-copy
This project is modified from https://github.com/vladshcherbin/rollup-plugin-copy. (Migrated from https://www.npmjs.com/package/@barusu/rollup-plugin-copy).
A few months ago I submitted a pr that supports watch mode, but no response was received, so I decided to release it separately.
Install
npm
npm install --save-dev @guanghechen/rollup-plugin-copy
yarn
yarn add --dev @guanghechen/rollup-plugin-copy
Usage
// rollup.config.js
import copy from '@guanghechen/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|string[]
): Path or glob of what to copydest (
string|string[]
): One or more destinations where to copyrename (
string | Function
): Change destination file or folder namefunction rename( name: string, ext: string, srcPath: string, ): string
transform (
Function
): Modify file contentsfunction transform( content: string | ArrayBuffer, srcPath: string, dstPath: string, ): Promise<string | ArrayBuffer>
copyOnce (
boolean|undefined
): Override the outer option.flatten (
boolean|undefined
): Override the outer option.verbose (
boolean|undefined
): Override the outer option.globbyOptions (
GlobbyOptions
): Override the outer option.fsExtraOptions (options of
fs-extra
): Override the outer option.
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) => `${name}-v1.${extension}`
}]
})
Transform file contents
copy({
targets: [{
src: 'src/index.html',
dest: 'dist/public',
transform: (contents, srcPath, destPath) => (
contents.toString()
.replace('__SCRIPT__', 'app.js')
.replace('__SOURCE_FILE_PATH__', srcPath)
.replace('__TARGET_FILE_NAME__', path.basename(srcPath))
)
}]
})
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'
})
watchHook
Type: string
| Default: buildStart
Rollup hook the this.addWatchFile should call. By default, addWatchFile
called on each rollup.rollup build.
Only be used in hooks during the build phase, i.e. in buildStart
, load
, resolveId
, and transform
.
copy({
targets: [{ src: 'assets/*', dest: 'dist/public' }],
watchHook: 'resolveId'
})
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
})
globbyOptions
See globby
copy({
targets: [{ src: 'src/assets/**/*.js', dest: 'dist' }],
globbyOptions: {
ignore: ['**/asset-1.js'],
},
})
fsExtraOptions
copy({
targets: [{ src: 'src/assets/**/*.js', dest: 'dist' }],
fsExtraOptions: {
copy: {} // Options of 'fs-extra'.copy
outputFile: { // Options of 'fs-extra'.outputFile
encoding: 'utf-8'
}
}
})
