RabbitMQ

Cloud Agnostic

Open Source

Distributes notifications across gateway instances via RabbitMQ fanout exchanges. Each Notiway instance binds its own queue to the exchange, so every instance receives every notification.

Environment Variables

Required

Variable	Description
`Infra__Plugins__Broker__Name`	Set to `RabbitMQ`
`Infra__Plugins__Broker__Version`	Plugin version (e.g., `0.12.0`)
`Infra__Plugins__Broker__Settings__ConnectionString`	RabbitMQ connection string (e.g., `amqp://guest:guest@localhost:5672`)

Optional

Variable	Default	Description
`Infra__Plugins__Broker__Settings__ExchangeName`	`notiway-notifications`	Name of the exchange used for broadcasting notifications
`Infra__Plugins__Broker__Settings__ExchangeType`	`fanout`	Exchange type (`fanout`, `direct`, `topic`, `headers`)

Usage

Publish notifications to the RabbitMQ exchange from your backend. The message body must be the notification JSON.

var factory = new ConnectionFactory { Uri = new Uri("amqp://guest:guest@localhost:5672") };
using var connection = await factory.CreateConnectionAsync();
using var channel = await connection.CreateChannelAsync();

var body = Encoding.UTF8.GetBytes(JsonSerializer.Serialize(notification));
await channel.BasicPublishAsync(exchange: "notiway-notifications", routingKey: "", body: body);

const amqp = require("amqplib");

const conn = await amqp.connect("amqp://guest:guest@localhost:5672");
const ch = await conn.createChannel();
ch.publish("notiway-notifications", "", Buffer.from(JSON.stringify(notification)));

import pika, json

connection = pika.BlockingConnection(pika.ConnectionParameters("localhost"))
channel = connection.channel()
channel.basic_publish(exchange="notiway-notifications", routing_key="", body=json.dumps(notification))

ConnectionFactory factory = new ConnectionFactory();
factory.setUri("amqp://guest:guest@localhost:5672");

try (Connection connection = factory.newConnection();
     Channel channel = connection.createChannel()) {
    String message = objectMapper.writeValueAsString(notification);
    channel.basicPublish("notiway-notifications", "", null, message.getBytes(StandardCharsets.UTF_8));
}

AMQP::TcpConnection connection(&handler, AMQP::Address("amqp://guest:guest@localhost:5672"));
