## What it is
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

## Facets
