Nchan vs Socket.IO: What are the differences?
What is Nchan? A scalable, flexible pub/sub server for the modern web. It is built as a module for the Nginx web server. It can be configured as a standalone server, or as a shim between your application and hundreds, thousands, or millions of live subscribers. It can buffer messages in memory, on-disk, or via Redis.
What is Socket.IO? Realtime application framework (Node.JS server). Socket.IO enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.
Nchan and Socket.IO belong to "Realtime Backend / API" category of the tech stack.
Some of the features offered by Nchan are:
- flexible pub/sub server
- Horizontally scalable (using Redis)
- Subscribe to hundreds of channels over a single subscriber connection.
On the other hand, Socket.IO provides the following key features:
- 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.
Nchan and Socket.IO are both open source tools. It seems that Socket.IO with 47.1K GitHub stars and 8.59K forks on GitHub has more adoption than Nchan with 2.35K GitHub stars and 243 GitHub forks.
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.
I would recommend looking hard into Firebase for this project, especially if you do not have dedicated full-stack or backend members on your team.
The real time database, as you mentioned, is a great option, but I would also look into Firestore. Similar to RTDB, it adds more functions and some cool methods as well. Also, another great thing about Firebase is you have easy access to storage and dead simple auth as well.
Node.js Express MongoDB Socket.IO and Apollo are great technologies as well, and may be the better option if you do not wish to cede as much control to third parties in your application.
Overall, I say if you wish to focus more time developing your React application instead of other parts of your stack, Firebase is a great way to do that.
Hello Noam đź‘‹,
I suggest taking a look at Ably, it has all the realtime features you need and the platform is designed to guarantee critical functionality at scale.
Here is an in depth comparison between Ably and Firebase
Hey Noam,
I would recommend you to take a look into 8base. It has features you've requested, also relation database and GraphQL API which will help you to develop rapidly.
Thanks, Ilya
