Pub/Sub for AI Agents in Node.js

Short summary

Pub/Sub messaging patterns enable AI agents in Node.js to execute heavy LLM processing asynchronously without blocking the event loop, improving application responsiveness. External message brokers provide persistence, fault tolerance, and horizontal scalability across distributed worker pools compared to native EventEmitter. Best for multi-agent swarms, real-time chat systems, and background semantic search ingestion pipelines.

• •Decouples AI agents using event-driven architecture instead of tightly coupled promises/HTTP
• •External brokers provide persistence and fault tolerance vs. native EventEmitter
• •Ideal for multi-agent systems, real-time chat, and background semantic search ingestion
