Redis Streams with Node.js Express: Easy Step-by-Step Guide
Want to build real-time event-driven systems using Redis Streams?
In this hands-on tutorial, you'll learn how Redis Streams work — from producers and consumers, to real-time subscriptions, event trimming, and integrating streams inside a Node.js Express API.
Redis Streams are perfect for:
✔ IoT sensor data
✔ Live notifications
✔ Real-time dashboards
✔ Event sourcing
✔ Activity feeds
If you're building reactive backends, this is essential learning.
💬 In this video, you’ll learn:
🔹 Redis Stream fundamentals
• Producers vs Consumers
• How event IDs work (timestamp + sequence number)
• Why stream entries are immutable
🔹 Core Redis Stream Commands
✅ XADD — Add new events
✅ XRANGE — Query events by time range
✅ XREVRANGE — Query newest → oldest
✅ XREAD — Subscribe to new events
✅ XLEN — Count stream events
✅ XTRIM — Trim events by max length
✅ XADD MAXLEN — Create fixed-length streams
🔹 Real Use Cases & Examples
• Adding time-based events
• Limiting results using COUNT
• Listening for new events with XREAD BLOCK
• Implementing TTL-like cleanup with XTRIM
• Creating IoT-like producers & consumers
🔹 Node.js Express Integration
• Updating a user’s location
• Logging location history to a Redis Stream
• Returning event results in API responses
• Viewing stream entries inside RedisInsight
