What Redis is good at
Strengths
- +Microsecond latency
- +Great for cache / queue
- +Rich data types
Tradeoffs
- −Memory-bound
- −Not a primary DB for most apps

Drop into Claude / Cursor to get idiomatic Redis code.
You're working with Redis. In-memory data store for caching, queues, and sessions. Best practices: - Lean on: microsecond latency - Lean on: great for cache / queue - Lean on: rich data types Things to watch for: - Watch out for: memory-bound - Watch out for: not a primary db for most apps General guidance: - Canonical docs: https://redis.io — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
Beginner's guide to Redis
In one line: An in-memory database — insanely fast, perfect for caching.
Redis keeps data in memory (RAM) instead of on disk, which makes it microseconds-fast. Usually used alongside a real database to cache results, store sessions, or as a queue.
