node-redis-warlock

node-redis-warlock is a distributed locking library for Node.js using Redis, version 1.0.2. It provides battle-hardened locking mechanisms such as simple lock, optimistic lock with retries, unlocking by lock ID, and TTL modification. It requires node-redis (v0.10 compatible) and Redis v2.6.12+. The library is synchronous in style, relying on callbacks rather than promises or async/await, which is a key differentiator from modern Redis locking libraries like redlock that support promises. Release cadence is sporadic; no recent updates.
