rm -rf for node.
npm install rimraf, or just drop rimraf.js somewhere.
The callback will be called with an error if there is one. Certain errors are handled for you:
ENOTEMPTY- rimraf will back off a maximum of
opts.maxBusyTriestimes before giving up.
ENOENT- If the file doesn't exist, rimraf will return successfully, since your desired outcome is already the case.
It can remove stuff synchronously, too. But that's not so good. Use the async API. It's better.
If installed with
npm install rimraf -g it can be used as a global command
rimraf <path> which is useful for cross platform support.
If you need to create a directory recursively, check out mkdirp.
