Real-time Communication
Socket.io provides real-time bidirectional event-based communication, which is essential for applications requiring instant data exchange, such as chat applications, live notifications, and multiplayer games.
Cross-browser Compatibility
Socket.io abstracts the differences between various web socket implementations across different browsers, ensuring consistent performance and compatibility.
Fallback Support
If WebSocket support is unavailable, Socket.io seamlessly falls back to other communication protocols such as long-polling, ensuring reliable connections.
Event-driven Architecture
Socket.io uses an event-driven approach, which simplifies the handling of complex real-time interactions through named events that can be easily managed and debugged.
Scalability Options
Socket.io can be effectively integrated with scaling solutions like Redis, which allows horizontal scaling and ensures that messages are correctly distributed among multiple server instances.
Easy to Use
Socket.io offers a straightforward API, making it easier for developers to implement real-time communication without deep knowledge of the underlying protocols.
Built-in Room and Namespace Support
With built-in support for rooms and namespaces, Socket.io allows more organized and efficient handling of events and connections within distinct channels or groups.

We have collected here some useful links to help you find out if Socket.io is good.
Check the traffic stats of Socket.io on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Socket.io on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Socket.io's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Socket.io on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

In line 32 we have the socket.io editaData event which handles data editing in the server. When the user clicks edit in the client, the server searches for the data using the findIndex method. If it exists it updates the data in the crudData array then it broadcasts the edited data to the client. - Source: dev.to / 4 months ago

Complexity: WebSockets require you to handle connection lifecycle events, such as errors and reconnections. While the code example I provided could suffice for simple use cases, more complex use cases might arise, like automatic reconnection and queueing messages sent by the client when the connection wasn't open. For that, you can either extend this code or use an external library like react-use-websocket for a... - Source: dev.to / 7 months ago

uWebSockets is web server written in C++. In our case we'll be using uWebSockets.js which has bindings to NodeJS. It can be used as a usual web server but the main feature is its WebSocket server. It is 10x faster than Socket.IO and 8.5x faster than Fastify. I have to say I haven't benchmarked it myself. I decided to use uWebSockets just because it feels more pure to my taste. For example it doesn't require... - Source: dev.to / 12 months ago

Socket.IO, a popular JavaScript library, is renowned for enabling real-time, bidirectional communication between clients and servers, making it a staple in web application development. Primarily used to build real-time applications like collaborative tools, messaging apps, and live data dashboards, Socket.IO stands out for its ease of use and flexibility across different programming languages.
In recent discussions and publications, Socket.IO is frequently lauded for its implementation simplicity, offering functionality such as automatic reconnection, packet buffering, and multiplexing. Developers appreciate its ability to handle complex real-time communication scenarios, ensuring smooth user experiences across varied applications. This includes building applications ranging from simple real-time notification systems to complex enterprise solutions involving dynamic and interactive user interfaces.
A notable advantage of Socket.IO is its abstraction layer over WebSockets, which simplifies the management of connection lifecycle events like reconnections and error handling. This feature is widely recognized as a differentiation point compared to other WebSocket libraries, offering developers a streamlined development experience. The implementation of Socket.IO in frameworks such as Node.js underscores its versatility, with developers leveraging its capabilities to create various applications, including score tickers, chatbots, dashboard APIs, and more.
However, opinions on Socket.IO are not universally positive. Some developers express reservations about its performance, particularly when compared to alternatives like uWebSockets. Critiques often center around the additional abstraction and helper functions Socket.IO provides, which some developers feel might lead to inefficiencies in certain situations. For instance, uWebSockets is perceived by some as a more "pure" and faster option, especially for those who prefer a more hands-on implementation without additional overhead.
Moreover, integration challenges have been reported, especially concerning specific scenarios like deploying applications with Next.js or managing local development environments. Some users encounter connectivity issues when deploying on certain platforms, occasionally finding the integration process cumbersome.
Despite these challenges, Socket.IO remains a widely-used library, praised for enabling custom, scalable communication solutions. Its ability to work cohesively with other technologies and frameworks—evidenced by its integration with ReactJS, Strapi, Flutter, and even Python-based applications—demonstrates its adaptability in the ever-evolving landscape of web development.
In conclusion, public opinion portrays Socket.IO as a robust tool for developers seeking to implement real-time functionalities in their applications. While performance considerations and integration complexities exist, its extensive feature set and ease of use continue to make it a popular choice for developers in crafting interactive and responsive web applications.
