What is a webSocket connection good for is a very clear question that is easy to answer without a super broad explanation.

What are WebSockets and why we use them? Alternatives for specific cases WebSockets provide us communication in full-duplex mode, that means the client can send and receive messages on the same channel.

Comparison of short and long polling techniques. For a more complete example, Socket. This library automatically switches between WebSockets and long polling, and also simplifies broadcasting messages to groups of connected users. Although you can manually write WebSocket server code, WebSockets is conveniently already built into popular frameworks. A few other implementations of WebSockets in larger projects are:. So, what types of projects can benefit from WebSockets? Any project that requires real-time, two-way communication is a great use case.

Here are just a few kinds of applications often powered by WebSockets:. A WebSocket connection is meant to be persisted, so can be overkill for simpler apps.

For a one-directional news feed, metrics feed, or any app where you need to update the client but not receive information in return, Server Sent Events or plain old HTTP calls are quicker and simpler to set up.

However, for multiplayer games and collaborative apps, WebSockets opens up a world of possibilities. The real-time web is evolving, and the WebSocket protocol is a crucial cog in its evolution. Go forth and use it for good! Why are you guys blogging so much lately?

Everything in moderation…that includes blog posts. Frequently posting new content is an effective way of growing traffic. I like this blog, WebSockets is indeed an interesting technology — my onw words, though. Thanks for share it. Good article, thanks, but you failed to mention SignalR! You would think a blog post from a company which uses. Yes exactly my thoughts. SignalR should be mentioned here. It is an extremely well build websockets implementation for.

Pretty good document, but it would have been better if you had mentioned both SignalR and the issues that cime with websockets if is not inplemented correctly such as SNAT. I agree with this being a good idea, but people have been so religious about not maintaining state. It is like talking to someone on the phone but hanging up after each sentence and calling back each time.

Why is webrtc even remotely related to websockets? Neither is dependent on the other and they do very different things. Webrtc was fresh a decade ago. No need to mention it for publicity today. One glaring thing that you did was to embolden lack of support from older browsers for SSE even though polyfills are available to enable support but not even mention the same for WS which has nothing to enable support.

Depending on browsers and purpose of application, they try to hold up the best suited. Suffice to say with 9 years of experience with many applications depending on the mechanism, working with WS is a code maintenance nightmare. The amount of code required to make it work in comparison to others is substantial. Not to mention, unlike others it even requires special configuration in high traffic servers and DDOS protection systems.

Requiring us to allocate a server admin with required knowledge. All other services are routed over SSE. It's, arguably, better for applications with large numbers of concurrent users because it doesn't require a constant TCP connection to the server it's harder to starve the server of TCP connections since they are periodically released. Though they come with the overhead of having to re-authenticate and re-authorize the client on each request.

And the server needs to implement some kind of event aggregation to overcome blackouts between re-connects. There are no JS APIs available for this mechanism, there is no re-connection handling, nor dropped client detection. When it comes to pushing data from the server to clients both WebSockets and Server-Sent Event will do the job. There are some subtle differences and incompatibilities, but there are libraries that solve those issues. If you don't need to send data to the server in "real-time" e.

They are the standard HTTP way of pushing data like notifications, messages or events to clients. And they can be added just by implementing an additional endpoint in a controller , lowering the need to refactor the existing code base in a well structured code base the "implementation cost" of both WS and SSE is the same , and making them somewhat faster to implement and bring the feature to market.

I don't have experience with long polling on projects with large numbers of concurrent users, so I can't attest the claims I've read about it being the better solution for those kinds of applications. Though, while we were reverse engineering Facebook's Messenger to add PGP to it I noticed that they utilize long polling to fetch messages.

On smaller projects I would recommend SSE over Long polling since it's easier to implement on both the server and client side.
