Getting Started with Redis Streams & Node.js

This project shows how to use Redis Node client to publish and consume messages using consumer groups.

This is a first basic example that use a single consumer.

Build

> cd redis-streams-101-node

> npm install

Run

You have access to a Redis instance/cluster.

Open 2 terminal windows

Run the Producer

> cd redis-streams-101-node

> node producer.js loop=1000 sleep=500

Where:

  • loop is the number of messages sent by the program (in a lopp)
  • sleep the time in milliseconds between each message post

Run the Consumer

> cd redis-streams-101-node

> node consumer.js

This will print all the messages that have not yet been consumed by the group.
