Excellent Javascript library for client-server communication **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Games | Small-Business (50 or fewer emp.) **Reviewed Date:** October 15, 2021 **What do you like best about Socket.Io?** For an appplication I am building, Socket.IO has greatly simplified passing of data between a server and many clients. Documentation is good but takes a bit of time to read through and figure out how to get started. Once you have the socket connection bit working though, adding new socket.on() functions for client-server communication is very straightforward. Socket.IO is a great alternative to other client-server communication methods such as REST. **What do you dislike about Socket.Io?** Documentation is decent but it's a bit difficult to figure out how to get started. Documentation reads more like a reference guide than a tutorial. **What problems is Socket.Io solving and how is that benefiting you?** Socket.IO solves passing of data between a server and many clients. It offers more flexibility than a REST-based client-server communication model, which only allows for synchronous stateless requests. Socket.IO is also easier to use once you have the socket connections working. ### 34.

The most exciting part for me is even though it uses WebSockets behind the scene, it hides the complexity of that and give us the abstract layer module to use. Also, it's so reliable compares it other event base messaging channels **What do you dislike about Socket.Io?** The only downside I would point out is it's only supporting NodeJs based applications at the moment. it would be great if they try to introduce similar features to other stacks going forward. **What problems is Socket.Io solving and how is that benefiting you?** As a software company, we at our organization uses socket.io most of the time in the places wherever nodejs event-based communication is needed. ### 39.

Hacking away with Socket.IO **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** April 11, 2019 **What do you like best about Socket.Io?** It is actively maintained. By "actively" I mean that all tickets are getting reviewed in a matter of a day-two and you get a meaningful response. very powerful due to its advanced features and its implementation in making RTA(Real-time Application). **What do you dislike about Socket.Io?** Callbacks of socket.io are the real downside. Callbacks offer no guarantees, if a callback needs to do a whole bunch of asynchronous tasks, there’s no way for it goes back to the caller. when sending events, there’s no way for the emitter to say to the caller “hey, this consumer has a slow network, can you hold off on emitting more events?” **What problems is Socket.Io solving and how is that benefiting you?** a very useful piece of technology, and is incredibly relevant today in spite of the popular frameworks that widespread support makes it redundant. I would recommend that it be used for highly interactive applications, its namespacing in particular is its strongest. Take advantage of the multi-argument and acknowledgment features. The approach to take also depends on the specific needs of your application. Socket.IO with Node.js offers a ridiculously simple way to get off the blocks for building web applications with soft real-time elements ## Socket.Io Discussions - [How many users can Socket.IO handle?](https://www.g2.com/discussions/how-many-users-can-socket-io-handle) - [What is Socket.IO and how it works?](https://www.g2.com/discussions/what-is-socket-io-and-how-it-works) - [What is Socket.IO good for?](https://www.g2.com/discussions/what-is-socket-io-good-for) - [Is](https://www.g2.com/discussions/is) - 1 upvote - [How do you contact me](https://www.g2.com/discussions/how-do-you-contact-me) - 1 upvote - [View Socket.Io pricing details and edition comparison](https://www.g2.com/products/socket-io/reviews?section=pricing&secure%5Bexpires_at%5D=2026-06-14+03%3A24%3A58+-0500&secure%5Bsession_id%5D=67505808-c870-4d9e-baa6-36f391149747&secure%5Btoken%5D=67b5806fddbdd72f90b9d77b25790d67a5bf215c892257f22351962e51978ade&format=llm_user) ## Top Socket.Io Alternatives - [Slack Connector for Jira](https://www.g2.com/products/slack-connector-for-jira/reviews) - 4.7/5.0 (267 reviews) - [Openfire](https://www.g2.com/products/openfire/reviews) - 4.7/5.0 (14 reviews) - [Gitter](https://www.g2.com/products/gitter/reviews) - 4.0/5.0 (49 reviews)
