    emptydir Build Status

    You now get to delete files recursively while preserving the directories from Node.Js and your terminal.

    installation

    You require npm to install/download this module.

    npm install emptydir

    If you wish to install it globally on your machine:

    npm install -g emptydir

    The module emptydir will be added in the correct node_modules directory and the command emptydir will be added to your terminal.

    usage

    from Node.Js (programmatic)

     
    var emptydir = require('emptydir');
     
    /* 
    * Assuming the variable 'my_path' holds a path to
    * a folder on your machine
    */
     
    /*
    * errs will be an array with all the errors that occurred
    * Otherwise null on success
    */
    emptydir.emptyDir(my_path, function (errs) {
        if (errs) {
            errs.forEach(function (err) {
                console.log(err.path + " failed due to " + err.code);
            });
        }
    });
     
    /*
    * callback is called per file(and not directory) being worked on.
    * err is null on success
    */
    emptydir.emptyDirs(my_path, function (err, path) {
        if (err) {
            console.log("Failed: " + path);
        }
        console.log("Success: " + path);
    });
     
    /*
    * Synchronous. Returns an array of all the errors that occurred while
    * working on the files in the directory.
    * On success, returns an empty array. Thus it is safe to immediately
    * loop through the errors in the array.
    */
    errs = emptydir.emptyDirsSync(my_path);
    errs.forEach(function () {
        console.log(err.path + " failed due to " + err.code);
    });

    notes

    By saying working on a file, we mean to try and remove it.

    All of the methods:

    1. If the path passed is a file, it is simply deleted. It's 'not amust the path points to a directory.
    2. Symbolic links are not dereferenced. They are deleted equally as files.

    Any of the Asynchronous methods:

    1. If a callback is not passed, the methods will complete as would have if callback was passed.

    emptydir.emptyDir(path [, callback])

    1. Callback is called only once after the working on the files is complete.
    2. On error, a list of all errors occurred during the recursive removal is passed to the callback.
    3. On success, error will be null

    emptydir.emptyDirs(path [, callback])

    1. The callback is called each time a file is worked on.
    2. path of the file worked on is always passed as the second argument to the callback on both success and error.

    emptydir.emptyDirsSync(path)

    1. The return value will always be an array. Thus no need to test for that.

    Note: The idea of the methods is to keep going even when an error is encountered. This ensures we remove as much files as possible.

    from your terminal (commandline)

    # output help info about available options. 
    $ emptydir -h
    $ emptydir --help
    ...
    # show the version number of emptydir installed. 
    $ emptydir --version
    ...
    # empty directoryA 
    $ emptydir directoryA
    ...
    # empty directoryA and directoryB 
    $ emptydir directoryA directoryB
    ...
    # be verbose while emptying directoryA 
    $ emptydir -v directoryA
    $ emptydir --verbose directoryA

    notes

    1. If a regular file, instead of a directory, is passed to emptydir it will just be deleted, if possible.
    2. Verbose option is unstable and may gave you false errors. That is, emptydir may remove some files but the commandline runner may report them back as failed.
