RabbitMQ tutorials

This directory contains the RabbitMQ tutorials, ported to amqplib.

Preparation

To run the tutorial code, you need amqplib installed. Assuming you are in a clone of the amqplib repository, from the tutorials directory:

npm install ../..

Then just run each file as a script, e.g., in bash

./send.js

or

node send.js

or

nave use 0.8 node send.js

A "Hello World" example, with one script sending a message to a queue, and another receiving messages from the same queue.

Using RabbitMQ as a work queue; new_task creates a task, and worker processes tasks. Multiple worker process will share the tasks among them. Long-running tasks are simulated by supplying a string with dots, e.g., '...' to new_task. Each dot makes the worker "work" for a second.

Using RabbitMQ as a broadcast mechanism. emit_log sends a "log" message to a fanout exchange, and all receive_logs processes receive log messages.

Using RabbitMQ as a routing ('somecast') mechanism. emit_log_direct sends a log message with a severity, and all receive_logs_direct processes receive log messages for the severities on which they are listening.

Extends the previous tutorial to routing with wildcarded patterns.
