Taulukko Messages

Taulukko Messages is a lightweight, efficient, and embedded JavaScript messaging library designed to facilitate communication between servers and components through a publish/subscribe model. This library is ideal for applications that require a reliable messaging system.

Features

• Ease of Configuration: Quickly set up message servers with a simple set of options.
• Flexible Publishing and Subscription: Send messages to multiple topics and easily subscribe to receive updates.
• Efficient Message Handling: Deal with received messages using an intuitive message handler system.
• High Performance: Designed to handle high volumes of messages with low latency.

Project Goals

• Provide a simple way to learn and implement messaging systems.
• Offer an easy-to-integrate, embedded messaging system solution.
• Ideal for small-scale projects seeking to avoid unnecessary complexities.
• Supports handling thousands of messages per second efficiently.

Project Limitations

• Does not support multi-server architectures.
• Lacks persistence; all data is lost if the server shuts down.
• Designed for vertical scaling, best suited for projects with a single server and a steady, controlled number of clients.

Installation

You can install Taulukko Messages via NPM:

npm install taulukko-messages

Usage Examples

Initializing the Server

import { Server } from 'taulukko-messages';

async function initServer() {

  const server = Server.create({
    port:7777
  });
  await server.open();
  return server;
}

Publishing and Subscribing to Messages

import { Publisher, Subscriber, Message } from 'taulukko-messages';

//Publishing
async function publishMessage() {
  const publisher = Publisher.create({
    server: "taulukko://localhost:7777",
    topics: ["topic.helloWorld"]
  });
  await publisher.open();
  await publisher.send("Hello World");
  await publisher.close();
}

// Subscribing
async function subscribeToTopic() {
  const subscriber = Subscriber.create({
    server: "taulukko://localhost:7777",
    topics: ["topic.helloWorld"],
    handler: (message: Message) => {
      console.log(`Received message on ${message.topic}: ${message.data}`);
    }
  });
  await subscriber.open();
}
