Redis in 5 Days

Redis is an in-memory data store used for caching, sessions, pub/sub messaging, and rate limiting. Learn the data types and patterns used in every production app.

  • Work with Redis strings, hashes, lists, sets, and sorted sets
  • Cache database query results to reduce latency
  • Implement session storage with Redis
  • Use pub/sub for real-time messaging
  • Set up Redis in production with Upstash or Redis Cloud
