Redis Scanner

redis-scanner (v0.1.1) is a Node.js utility that wraps Redis SCAN, SSCAN, HSCAN, and ZSCAN commands to simplify iteration over large key sets without blocking the server. It supports both synchronous and asynchronous usage, and offers two integration methods: binding scan methods directly to a RedisClient instance, or creating standalone Scanner objects. Currently pre-1.0.0, with potential breaking changes, it is no longer actively maintained (last commit in 2016). Key differentiators: automatic cursor management, MATCH/COUNT options in `options`, and reusable Scanner objects. Not compatible with modern Redis clients; prefer `ioredis` or `node-redis` built-in scan iterators.
