fs-vacuum

Remove the empty branches of a directory tree, optionally up to (but not including) a specified base directory. Optionally nukes the leaf directory.

Usage

var logger = require("npmlog");
var vacuum = require("fs-vacuum");

var options = {
  base  : "/path/to/my/tree/root",
  purge : true,
  log   : logger.silly.bind(logger, "myCleanup")
};

/* Assuming there are no other files or directories in "out", "to", or "my",
 * the final path will just be "/path/to/my/tree/root".
 */
vacuum("/path/to/my/tree/root/out/to/my/files", function (error) {
  if (error) console.error("Unable to cleanly vacuum:", error.message);
});

vacuum(directory, options, callback)

• directory {String} Leaf node to remove. Must be a directory, symlink, or file.

  • purge {Boolean} If set, nuke the whole leaf directory, including its contents.
