    Removing of folders and files for Webpack

    A plugin for webpack that removes files and folders before and after compilation.

    Content

    Installation

    • With npm:
    npm install remove-files-webpack-plugin
    • With yarn:
    yarn add remove-files-webpack-plugin

    Support

    The plugin works on any OS and webpack >= 2.2.0.

    Usage

    const RemovePlugin = require('remove-files-webpack-plugin');
    
    module.exports = {
        plugins: [
            new RemovePlugin({
                before: {
                    // parameters for "before normal compilation" stage.
                },
                watch: {
                    // parameters for "before watch compilation" stage.
                },
                after: {
                    // parameters for "after normal and watch compilation" stage.
                }
            })
        ]
    };

    Notes for Windows users

    Single backward slash

    JavaScript uses it for escaping. If you want to use backward slash, then use double backward slash. Example: C:\\Windows\\System32\\cmd.exe. By the way, single forward slashes are also supported.

    Segment separator

    All paths that you get or see from the plugin will contain platform-specific segment separator (i.e. slash): \\ on Windows and / on POSIX. So, for example, even if you passed folders or files with / as separator, TestObject.method will give you a path with \\ as segment separator.

    Per-drive working directory

    From Node.js documentation:

    On Windows Node.js follows the concept of per-drive working directory. This behavior can be observed when using a drive path without a backslash. For example, path.resolve('c:\\') can potentially return a different result than path.resolve('c:'). For more information, see this MSDN page.

    Parameters

    Name Type Default Namespace Description
    root string . All A root directory.
    Not absolute paths will be appended to this.
    Defaults to where package.json and node_modules are located.
    include string[] [] All A folders or files for removing.
    exclude string[] [] All A folders or files for excluding.
    test TestObject[] [] All A folders for testing.
    TestObject.folder string Required All A path to the folder (relative to root).
    TestObject.method (absolutePath: string) => boolean Required All A method that accepts an item path (root + folderPath + fileName) and
    returns value that indicates should this item be removed or not.
    TestObject.recursive boolean false All Apply this method to all items in subdirectories.
    beforeRemove (
    absoluteFoldersPaths: string[],
    absoluteFilesPaths: string[]
    ) => boolean
    undefined All If specified, will be called before removing.
    Absolute paths of folders and files that
    will be removed will be passed into this function.
    If returned value is true,
    then remove process will be canceled.
    Will be not called if items for removing
    not found, emulate: true or skipFirstBuild: true.
    afterRemove (
    absoluteFoldersPaths: string[],
    absoluteFilesPaths: string[]
    ) => void
    undefined All If specified, will be called after removing.
    Absolute paths of folders and files
    that have been removed will be passed into this function.
    Will be not called if emulate: true or skipFirstBuild: true.
    trash boolean false All Move folders and files to the trash (recycle bin) instead of permanent removing.
    It is an async operation and you won't be able to control an execution chain along with other webpack plugins!
    afterRemove callback behavior is undefined (it can be executed before, during or after actual execution).
    Requires Windows 8+, macOS 10.12+ or Linux.
    log boolean true All Print messages of "info" level
    (example: "Which folders or files have been removed").
    logWarning boolean true All Print messages of "warning" level
    (example: "An items for removing not found").
    logError boolean false All Print messages of "error" level
    (example: "No such file or directory").
    logDebug boolean false All Print messages of "debug" level
    (used for debugging).
    emulate boolean false All Emulate remove process.
    Print which folders and files will be removed
    without actually removing them.
    Ignores log parameter.
    allowRootAndOutside boolean false All Allow removing of root directory or outside root directory.
    It is kind of safe mode.
    Don't turn it on if you don't know
    what you actually do!
    readWebpackConfiguration boolean false All Change parameters based on webpack configuration.
    Following webpack parameters are supported: stats (controls logging).
    These webpack parameters have priority over the plugin parameters.
    See webpack documentation for more - https://webpack.js.org/configuration
    skipFirstBuild boolean false watch First build will be skipped.
    beforeForFirstBuild boolean false watch For first build before parameters will be applied,
    for subsequent builds watch parameters will be applied.

    How to set

    You can pass these parameters into any of the following keys: before, watch or after. Each key is optional, but at least one should be specified.

    • before – executes once before "normal" compilation.
    • watch – executes every time before "watch" compilation.
    • after – executes once after "normal" compilation and every time after "watch" compilation.

    Namespace

    "Namespace" means where particular parameter will be applied. For example, "All" means particular parameter will work in any key (before, watch, after), watch means particular parameter will work only in watch key.

    Compilation modes

    • "normal" compilation means full compilation.
    • "watch" compilation means first build is a full compilation and subsequent builds is a short rebuilds of changed files.
