Package detail

Copy Webpack Plugin

This is a webpack plugin that copies individual files or entire directories to the build directory.

Getting started

Install the plugin:

npm install --save-dev copy-webpack-plugin

Usage

new CopyWebpackPlugin([patterns], options)

A pattern looks like: { from: 'source', to: 'dest' }

Pattern properties:

• from
  • is required
  • can be an absolute or path relative to the context
  • can be a file or directory
  • can be a glob
• to
  • is optional
  • if not absolute, it's relative to the build root
  • must be a directory if from is a directory
• toType
  • is optional
  • is ignored if from is a directory
  • defaults to 'file' if to has an extension
  • defaults to 'dir' if to doesn't have an extension
• force
  • is optional
  • defaults to false
  • forces the plugin to overwrite files staged by previous plugins
• context
  • is optional
  • defaults to the base context
  • is a pattern specific context
• flatten
  • is optional
  • defaults to false
  • removes all directory references and only copies file names
  • if files have the same name, the result is non-deterministic
• ignore
  • additional globs to ignore for this pattern

Available options:

• ignore
  • an array of files and directories to ignore
  • accepts globs
  • globs are evaluated on the from path, relative to the context
• copyUnmodified
  • is optional
  • defaults to false (only copies modified files)
  • true copies all files while using watch or webpack-dev-server

Examples

var CopyWebpackPlugin = require('copy-webpack-plugin');
var path = require('path');

module.exports = {
    context: path.join(__dirname, 'app'),
    devServer: {
        // This is required for webpack-dev-server if using a version <3.0.0.
        // The path should be an absolute path to your build destination.
        outputPath: path.join(__dirname, 'build')
    },
    plugins: [
        new CopyWebpackPlugin([
            // {output}/file.txt
            { from: 'from/file.txt' },

            // {output}/to/file.txt
            { from: 'from/file.txt', to: 'to/file.txt' },

            // {output}/to/directory/file.txt
            { from: 'from/file.txt', to: 'to/directory' },

            // Copy directory contents to {output}/
            { from: 'from/directory' },

            // Copy directory contents to {output}/to/directory/
            { from: 'from/directory', to: 'to/directory' },

            // Copy glob results to /absolute/path/
            { from: 'from/directory/**/*', to: '/absolute/path' },

            // Copy glob results (with dot files) to /absolute/path/
            {
                from: {
                    glob:'from/directory/**/*',
                    dot: true
                },
                to: '/absolute/path'
            },

            // Copy glob results, relative to context
            {
                context: 'from/directory',
                from: '**/*',
                to: '/absolute/path'
            },

            // {output}/file/without/extension
            {
                from: 'path/to/file.txt',
                to: 'file/without/extension',
                toType: 'file'
            },

            // {output}/directory/with/extension.ext/file.txt
            {
                from: 'path/to/file.txt',
                to: 'directory/with/extension.ext',
                toType: 'dir'
            }
        ], {
            ignore: [
                // Doesn't copy any files with a txt extension    
                '*.txt',

                // Doesn't copy any file, even if they start with a dot
                { glob: '**/*', dot: true }
            ],

            // By default, we only copy modified files during
            // a watch or webpack-dev-server build. Setting this
            // to `true` copies all files.
            copyUnmodified: true
        })
    ]
};
