FileManager Webpack Plugin

This Webpack plugin allows you to copy, archive (.zip/.tar/.tar.gz), move, delete files and directories before and after builds

Install

npm install filemanager-webpack-plugin --save-dev
# or
yarn add filemanager-webpack-plugin --dev

Usage

// webpack.config.js:

const FileManagerPlugin = require('filemanager-webpack-plugin');

export default {
  // ...rest of the config
  plugins: [
    new FileManagerPlugin({
      events: {
        onEnd: {
          copy: [
            { source: '/path/fromfile.txt', destination: '/path/tofile.txt' },
            { source: '/path/**/*.js', destination: '/path' },
          ],
          move: [
            { source: '/path/from', destination: '/path/to' },
            { source: '/path/fromfile.txt', destination: '/path/tofile.txt' },
          ],
          delete: ['/path/to/file.txt', '/path/to/directory/'],
          mkdir: ['/path/to/directory/', '/another/directory/'],
          archive: [
            { source: '/path/from', destination: '/path/to.zip' },
            { source: '/path/**/*.js', destination: '/path/to.zip' },
            { source: '/path/fromfile.txt', destination: '/path/to.zip' },
            { source: '/path/fromfile.txt', destination: '/path/to.zip', format: 'tar' },
            {
              source: '/path/fromfile.txt',
              destination: '/path/to.tar.gz',
              format: 'tar',
              options: {
                gzip: true,
                gzipOptions: {
                  level: 1,
                },
                globOptions: {
                  // https://github.com/Yqnn/node-readdir-glob#options
                  dot: true,
                },
              },
            },
          ],
        },
      },
    }),
  ],
};

Options

new FileManagerPlugin({
  events: {
    onStart: {},
    onEnd: {},
  },
  runTasksInSeries: false,
  runOnceInWatchMode: false,
});

File Events

• onStart: Commands to execute before Webpack begins the bundling process

Note:

OnStart might execute twice for file changes in webpack context.

new webpack.WatchIgnorePlugin({
  paths: [/copied-directory/],
});

• onEnd: Commands to execute after Webpack has finished the bundling process

File Actions

Copy

Copy individual files or entire directories from a source folder to a destination folder. Also supports glob pattern.

[
  { source: '/path/from', destination: '/path/to' },
  {
    source: '/path/**/*.js',
    destination: '/path',
    options: {
      flat: false,
      preserveTimestamps: true,
      overwrite: true,
    },
    globOptions: {
      dot: true,
    },
  },
  { source: '/path/fromfile.txt', destination: '/path/tofile.txt' },
  { source: '/path/**/*.{html,js}', destination: '/path/to' },
  { source: '/path/{file1,file2}.js', destination: '/path/to' },
];

Options

• source[string] - a file or a directory or a glob
• destination[string] - a file or a directory.
• options [object] - copy options
• globOptions [object] - options to forward to glob options(See available options here)

Caveats

• if source is a glob, destination must be a directory
• if source is a file and destination is a directory, the file will be copied into the directory

Delete

Delete individual files or entire directories. Also supports glob pattern

['/path/to/file.txt', '/path/to/directory/', '/another-path/to/directory/**.js'];

or

[
  {
    source: '/path/to/file.txt',
    options: {
      force: true,
    },
  },
];

Move

Move individual files or entire directories.

[
  { source: '/path/from', destination: '/path/to' },
  { source: '/path/fromfile.txt', destination: '/path/tofile.txt' },
];

Options

• source[string] - a file or a directory or a glob
• destination[string] - a file or a directory.

Mkdir

Create a directory path with given path

['/path/to/directory/', '/another/directory/'];

Archive

Archive individual files or entire directories. Defaults to .zip unless 'format' and 'options' provided. Uses node-archiver

[
  { source: '/path/from', destination: '/path/to.zip' },
  { source: '/path/**/*.js', destination: '/path/to.zip' },
  { source: '/path/fromfile.txt', destination: '/path/to.zip' },
  { source: '/path/fromfile.txt', destination: '/path/to.zip', format: 'tar' },
  {
    source: '/path/fromfile.txt',
    destination: '/path/to.tar.gz',
    format: 'tar', // optional
    options: {
      // see https://www.archiverjs.com/docs/archiver
      gzip: true,
      gzipOptions: {
        level: 1,
      },
      globOptions: {
        // https://github.com/Yqnn/node-readdir-glob#options
        dot: true,
      },
    },
  },
];

• source[string] - a file or a directory or a glob
• destination[string] - a file.
• format[string] - Optional. Defaults to extension in destination filename.
• options[object] - Refer https://www.archiverjs.com/archiver

Order of execution

If you need to preserve the order in which operations will run you can set the onStart and onEnd events to be Arrays. In this example below, in the onEnd event the copy action will run first, and then the delete after:

{
  onEnd: [
    {
      copy: [{ source: './dist/bundle.js', destination: './newfile.js' }],
    },
    {
      delete: ['./dist/bundle.js'],
    },
  ];
}

Other Options

• runTasksInSeries [boolean] - Run tasks in series. Defaults to false
• runOnceInWatchMode [boolean] - The onStart event will be run only once in watch mode. Defaults to false

For Example, the following will run one after the other

copy: [
  { source: 'dist/index.html', destination: 'dir1/' },
  { source: 'dir1/index.html', destination: 'dir2/' },
];

• context [string] - The directory, an absolute path, for resolving files. Defaults to webpack context.
