NATS vs Socket.IO: What are the differences?

Introduction

This Markdown code provides a comparison between NATS and Socket.IO. NATS and Socket.IO are both popular technologies used for real-time communication, but they have some key differences that set them apart. In the following paragraphs, we will explore these differences in more detail.

Scalability: NATS is a lightweight and high-performance messaging system that is designed for scalability. It is known for its efficiency and ability to handle large volumes of messages with minimal latency. On the other hand, Socket.IO is a library that provides real-time websocket communication between the browser and the server. While Socket.IO can handle a decent amount of traffic, it may not be as scalable as NATS when it comes to handling a massive number of connections.
Protocol: NATS uses a publish-subscribe messaging pattern, where publishers send messages on a specific subject or topic, and subscribers receive messages that match their subscribed subjects. It follows a simple and lightweight protocol, making it more efficient for real-time messaging. Socket.IO, on the other hand, uses the WebSocket protocol, which provides a full-duplex communication channel over a single TCP connection. This allows for real-time bidirectional communication between the client and the server.
Language Support: NATS offers support for various programming languages, including Go, Java, JavaScript, .NET, Python, and Ruby. This makes it a versatile choice for developers working in different languages. On the other side, Socket.IO primarily focuses on JavaScript and is commonly used with Node.js for server-side implementation. While there are some community-supported libraries for other languages, the main focus of Socket.IO remains on JavaScript.
Features: NATS is designed to be a simple and lightweight messaging system with minimal dependencies. It offers core messaging capabilities like publish-subscribe, request-reply, and load balancing. In comparison, Socket.IO provides additional features like namespaces, room support, and event-driven communication. It allows developers to organize connected clients into groups and emit events to specific groups or individual clients.
Compatibility: NATS can be used as a standalone messaging system or as a middleware within a larger architecture. It provides client libraries for various platforms and can integrate with other messaging systems like Kafka and MQTT. Socket.IO, on the other hand, is primarily used for real-time communication between the browser and the server. It is commonly employed in web applications or mobile apps that require real-time updates and notifications.
Community and Ecosystem: NATS has a strong community and an active ecosystem of client libraries, frameworks, and integrations. It is widely adopted by companies and developers for building scalable and reliable distributed systems. Socket.IO also has a large user community and an extensive ecosystem of plugins and integrations. Being focused on real-time web applications, Socket.IO has gained popularity and support from web developers.

In summary, NATS and Socket.IO differ in terms of scalability, protocol, language support, features, compatibility, and community. While NATS focuses on lightweight messaging and scalability, Socket.IO provides real-time bidirectional communication primarily for web applications. Both technologies have their strengths and best fit different use cases.

Node.js

ExpressJS

React

We are starting to work on a web-based platform aiming to connect artists (clients) and professional freelancers (service providers). In-app, timeline-based, real-time communication between users (& storing it), file transfers, and push notifications are essential core features. We are considering using Node.js, ExpressJS, React, MongoDB stack with Socket.IO & Apollo, or maybe using Real-Time Database and functionalities of Firebase.

Flutter

Socket.IO

We (my team) are building an App where we want to have Bi-directional texting, Single Directional Picture, and audio transfer.

We are building all this using Flutter.

There will essentially be 3 apps, 2 Mobile-based (Android and iOS) and 1 Microsoft Based. We've built up most of the code already, and made a few major mistakes but fixed it(namely had no proper state management).

How things will work:

Person A has a Mobile app 1, Person A presses a button that sends a "communication request" into a Pool of requests. Person B on Desktop App chooses a "communication request" from the pool, and engages in Bi-directional texting with Person A. Person B also opens communication with Person C who is on Mobile app 2, and they engage in Bi-directional texting. Person C will be notified of communication requests through Push Notifications.

So far we've been using Socket.IO, however, I'm starting to think that's not the best.

A problem we've encountered so far is that Person A(Mobile App 1 User), is the person who sends a "communication request" into the "Communication Pool". The Mobile App 1 User, can "cancel" the communication at any point in time. When they do that, I would like for a notification to be sent to Person B, the Desktop User, For them to pick up another communication request.

I am not sure how this should be done however, should it be done in the Back-end, then how does the Front-end get notified of the change?

Any advice on which to choose?

Review

It really depends on how you want to do it. If you use Socket.IO, you do have to have your own server running somewhere else, a good free one is Heroku. Pusher is nice if you know what you are trying to do, know your limits, and how to do it. While Socket.IO allows more flexibility if you need to do something crazy, Pusher is great if you're just doing standard real-time data transfer because there is minimal setup. The only other thing about Pusher is that it is not entirely free, so if you know the pricing, know how much you are going to use, and are willing, you could easily use Pusher.

Detailed Comparison

Socket.IO	NATS
It enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.	Unlike traditional enterprise messaging systems, NATS has an always-on dial tone that does whatever it takes to remain available. This forms a great base for building modern, reliable, and scalable cloud and distributed systems.
Real-time analytics - Push data to clients that gets represented as real-time counters, charts or logs.;Binary streaming - Starting in 1.0, it's possible to send any blob back and forth: image, audio, video.;Instant messaging and chat - Socket.IO's "Hello world" is a chat app in just a few lines of code.;Document collaboration - Allow users to concurrently edit a document and see each other's changes.	-
