Messaging Foundations
Why async messaging, what RabbitMQ and AMQP are, the core concepts, and your first publish/consume. Start →
RabbitMQ — From Zero to Hero
A standalone, beginner→advanced course on designing async systems with RabbitMQ. From the AMQP model and exchange routing to acknowledgements, publisher confirms, dead-letter exchanges, work queues, RPC, quorum queues, and scaling — every topic with the why, the trade-offs, and Node, Python, and Go examples side by side.
What you’ll learn
Section titled “What you’ll learn”Exchanges & Routing
Direct, fanout, topic, and headers exchanges — how a message finds its queues. Route →
Queues & Messages
Queue and message properties, acknowledgements, prefetch/QoS, and TTL & limits. Tune →
Reliability & Delivery
Publisher confirms, dead-letter exchanges, delivery guarantees, and durability. Harden →
Consumer Patterns
Work queues, publish/subscribe, RPC over RabbitMQ, and retry with backoff. Apply →
Operations & Scaling
Clustering & quorum queues, connections & channels, monitoring, and flow control. Scale →
Patterns & Alternatives
Messaging patterns, RabbitMQ vs Kafka, Streams, and a production-grade consumer. Extend →
How this course works
Section titled “How this course works”The model first, then the code
Every lesson starts from the AMQP model — producers, exchanges, bindings, queues, consumers — so the code is obvious once you can see how a message flows.
Three languages side by side
Producer and consumer examples in Node (amqplib), Python (pika), and Go (amqp091) through synced tabs — pick your language once and follow it everywhere.
Design, not just syntax
Every topic covers the why and the trade-offs — when to ack manually, how to guarantee delivery, how to handle poison messages, and when a queue is the wrong tool.
Diagrams that explain
Exchange routing, acknowledgement flow, dead-letter retry, and RPC correlation as theme-aware Mermaid diagrams. Bilingual (English / ไทย) with saved quiz progress.
