LockDB is a cross-platform tool you can use to handle process/event locking and avoid race conditions. It is sometimes also known as a semaphore.

There are packages for Node.js / Browser / Bun / NPM, Deno, and you can also use it as a CLI.

The new LockDB release supports a feature request common for complex locking necessities: The ability to lock, unlock, and check multiple locks.

I understand new features aren't _generally_ accepted [1] here, but this one seemed "juicy" enough for it. Feel free to remove the post if I'm wrong, and I apologize in that case!
