rabbitmq-describer

Generates a static page that describes the rabbitMQ behavior in a specific app.

It will show a graph with nodes and links, describing which routing keys are being used and which queues are listening to those routing keys.

Very useful to have a graphical overview of a complex rabbitmq system.

How it works

It will connect to your rabbitMQ management url (default is http://localhost:15672) and get the basic metadata of your queues and routing keys. Then it will display the connections in a graph using Cytoscape.js, a graphical lib for visualization in graph theory.

Installation

npm install rabbitmq-describer

How to use it

You can serve it with express for instance

const rabbitmqDescriber = require('rabbitmq-describer');
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  const html = await rabbitmqDescriber({
    user: "guest",
    password: "guest",
    managementURL: "http://localhost:15672/",
  });
  res.format({
    "text/html": function () {
      res.end(html);
    },
  });
})

app.listen(port, () => {
  console.log(`App listening on port ${port}`)
})

Save that into index.js and run

npm start

Go to http://localhost:3000/ to see the live version description of yout rabbitmq system.
