While I love Node.js, I've found myself missing some functions. Things like recursively deleting/chmodding a directory (or even deep copying a directory) shouldn't need to be re-invented time and time again.
That said, here's my attempt at a re-usable solution, at least until something more formalized gets integrated into Node.js (hint hint). wrench.js is fairly simple to use - check out the documentation/examples below:
npm install wrench
var wrench = require("./wrench"); // Recursively delete the entire sub-tree of a directory, then kill the directory wrench.rmdirSyncRecursive("my_directory_name"); // Recursively chmod the entire sub-tree of a directory wrench.chmodSyncRecursive("my_directory_name", 0755); // Deep-copy an existing directory wrench.copyDirSyncRecursive("directory_to_copy", "location_where_copy_should_end_up");
It should be noted that these are all currently synchronous operations. I'll be adding asynchronous versions of chmod/copy in the near future, but rmdir is one that really can't exist in an asynchronous fashion.
