Socket.IO vs ws: What are the differences?

Developers describe Socket.IO as "Realtime application framework (Node.JS server)". It enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed. On the other hand, ws is detailed as "A Node.js WebSocket library". It is a simple to use, blazing fast, and thoroughly tested WebSocket client and server implementation.

Socket.IO and ws belong to "Realtime Backend / API" category of the tech stack.

Some of the features offered by Socket.IO are:

  • 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.

On the other hand, ws provides the following key features:

  • Simple to use
  • Blazing fast
  • WebSocket client and server for Node.js

Socket.IO and ws are both open source tools. It seems that Socket.IO with 47.7K GitHub stars and 8.68K forks on GitHub has more adoption than ws with 12.4K GitHub stars and 1.6K 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.

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

        What are some alternatives to Socket.IO and ws?
        SignalR
        SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization.
        SocketCluster
        SocketCluster is a fast, highly scalable HTTP + realtime server engine which lets you build multi-process realtime servers that make use of all CPU cores on a machine/instance. It removes the limitations of having to run your Node.js server as a single thread and makes your backend resilient by automatically recovering from worker crashes and aggregating errors into a central log.
        PubNub
        PubNub makes it easy for you to add real-time capabilities to your apps, without worrying about the infrastructure. Build apps that allow your users to engage in real-time across mobile, browser, desktop and server.
        Pusher
        Pusher is the category leader in delightful APIs for app developers building communication and collaboration features.
        ExpressJS
        Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications.
