If you have non-JavaScript components on the server side, there is a possibility of problems with Socket.IO. For example, your server-side language might be Java, .NET, or Ruby on Rails. For a Socket.IO-like experience, you must use the messaging library for that language or framework. However, none of these libraries are fully compatible with Socket.IO. If you build your messaging functionality on top of a basic WebSocket library like ws Node, the developer experience will vary from library to library. Scalability, reliability and assurance Features of a messaging library or protocol are only part of the story. Once you're in production, its ability to scale, stay online, and reliably deliver data comes into focus. Socket.
IO and WebSocket lose points in this area: Scalability: Socket.IO: It should be noted that Socket.IO can scale phone numbers list vertically without requiring any special modification or configuration. Just add more memory, processor and network bandwidth to handle the increased traffic. Research shows that a single server can handle 10,000 simultaneous connections, but it depends on the type of traffic and server capacity. Outbound scaling becomes more complex as more servers are added. You need a load balancer and stabilization layer to keep track of which server clients are connected to. WebSocket: Adding more capacity to a server is simple, but it ends up costing you less. Horizontal scaling is possible, but you need a way to keep track of each server's sessions and balance the load between them. Reliability: Scalability and reliability are two related concepts. If you can scale your infrastructure horizontally, you can withstand the failure of a part of it. However, Socket.IO and WebSocket are designed to work in only one place.
If that section becomes unavailable, your entire real-time messaging capacity will also be disabled. Guarantees : Socket.IO and WebSocket do not provide robust messaging guarantees. Whichever you choose, you need to create a manual function to check whether the messages are delivered or not. Performance comparison of Socket.IO and WebSocket In general, Socket.IO and WebSocket performance is equivalent using similar hardware and networks. However, Socket.IO is slightly slower than WebSocket because Socket.IO always starts with an HTTP connection and then tries to upgrade to WebSocket if one is available. Additionally, Socket.IO supports multiplexing, which allows it to send messages to multiple clients simultaneously. This feature can be useful, but it will also add processing overhead. Advantages and disadvantages of Socket.IO and WebSocket picture (3) Ultimately, the performance of Socket.IO and WebSocket depends largely on how they are implemented. If you implement more advanced functions along with WebSocket, the performance may decrease slightly. All in all, Socket.IO and WebSocket are both viable options for real-time messaging.
