A Node.js/TypeScript implementation of the Redlock algorithm for distributed, highly-available Redis locks. It provides strong locking guarantees across single or multiple independent Redis instances or clusters, with auto-extending locks via a `using` API.

Use cases

• implement distributed locks across multiple redis instances
• prevent concurrent job execution in a node.js cluster
• acquire a mutex over shared resources in a distributed system
• auto-extending locks for long-running node.js tasks
• fault-tolerant locking with multiple independent redis nodes

When to choose

• you need strong distributed locking guarantees with Redis in Node.js
• you run multiple independent Redis instances or clusters and need quorum-based locking
• you want automatic lock extension and abort signaling for long-running routines

When to avoid

• you use a language or runtime other than Node.js
• you need locks without Redis, e.g. database- or etcd-based coordination
• you only need single-process mutexes, where in-process locks suffice
