This is a fork of Copy Webpack Plugin

Primarily forked to add the option to copy file permissions

Webpack Plugin Copy

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 webpack-plugin-copy

Usage

new WebpackPluginCopy([patterns], options)

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

Pattern properties:

| Name | Required | Default | Details | |------|----------|------------ |---------------------------------------------------------| | from | Y | | examples:'relative/file.txt''/absolute/file.txt''relative/dir''/absolute/dir''**/*'{glob:'**/*', dot: true}Globs accept minimatch options | | to | N | output root if from is file or dirresolved glob path if from is glob | examples:'relative/file.txt''/absolute/file.txt''relative/dir''/absolute/dir''relative/[name].[ext]''/absolute/[name].[ext]'Templates are file-loader patterns | | toType | N | 'file' if to has extension or from is file'dir' if from is directory, to has no extension or ends in '/''template' if to contains a template pattern | | | context | N | compiler.options.context | A path that determines how to interpret the from path | | flatten | N | false | Removes all directory references and only copies file namesIf files have the same name, the result is non-deterministic | | ignore | N | [] | Additional globs to ignore for this pattern | | transform | N | function(content, path) {  return content;} | Function that modifies file contents before writing to webpack | | force | N | false | Overwrites files already in compilation.assets (usually added by other plugins) | | copyPermissions | N | false | Applies source file permissions to destination files |

Available options:

| Name | Default | Details | | ---- | ------- | ------- | | ignore | [] | Array of globs to ignore (applied to from) | | copyUnmodified | false | Copies files, regardless of modification when using watch or webpack-dev-server. All files are copied on first build, regardless of this option. | | debug | 'warning' | options:'warning' - only warnings'info' or true - file location and read info'debug' - very detailed debugging info

Examples

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

module.exports = {
    context: path.join(__dirname, 'app'),
    devServer: {
        // This is required for older versions of webpack-dev-server
        // if you use absolute 'to' paths. The path should be an
        // absolute path to your build destination.
        outputPath: path.join(__dirname, 'build')
    },
    plugins: [
        new WebpackPluginCopy([

            // {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/

                to: '/absolute/path'
            },

            // Copy glob results, relative to context

        ], {
            ignore: [

                { glob: '**/*', dot: false }
            ],

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

Testing

Run npm test

"EMFILE: too many open files" or "ENFILE: file table overflow"

Globally patch fs with graceful-fs

npm install graceful-fs --save-dev

At the top of your webpack config, insert this

var fs = require('fs');
var gracefulFs = require('graceful-fs');
gracefulFs.gracefulify(fs);

This doesn't copy my files with webpack-dev-server

This plugin is not using fs to copy files to the filesystem but is depending on webpack's in-memory filesystem:

... webpack-dev-server will serve the static files in your build folder. It’ll watch your source files for changes and when changes are made the bundle will be recompiled. This modified bundle is served from memory at the relative path specified in publicPath (see API). It will not be written to your configured output directory.

If you must have webpack-dev-server write to your output directory, you can force it with the write-file-webpack-plugin.
