WebSockets for fun and profit


Seamless communication is a must on the modern web. As internet speeds increase, we expect our data in real time. To address this need, WebSocket, a popular communication protocol finalized inenables websites to send and receive data without delay. With WebSockets, you can build multiplayer games, chat apps, and collaboration software that work on the open web. I built several projects with WebSockets before I started to wonder what exactly was happening under the hood. In this article, we will:. By the end of this piece, you should feel comfortable discussing how WebSockets work, and maybe even inspired to use it in your next project. The key word in that definition is two-way : with WebSocket, both the client and the server can trigger communication with one another, and both can send messages, at the same time. Why is this a big deal? In a traditional HTTP system, which is used by the majority of websites today, a web server is designed to receive and respond to requests from clients via HTTP messages. This traditional communication can only be initiated in one direction: from the client to the server. Server code defines what type of requests the server should expect and how to respond to each of them. A common metaphor for this type of communication is a restaurant kitchen. It goes something like this:. The important thing to note here is that the kitchen has no idea who the order is coming from. We do have ways around that—for example, clients can send along cookies that help the server identify the client, but the HTTP messages themselves are distinct and are read and fulfilled independently. The kitchen has no concept of you —only the orders that come in. In server-speak, the only way for clients to get updated information from the server is to send requests. You send a message to the server, as a request with some text as a payload. The server receives your request and stores the message. As it stands, you and your friend—both clients—need to constantly check the server for updates, introducing awkward delays between every message. Here it is! One dead simple solution to this problem is a technique called short polling. Just have the client ping the server repeatedly, say, every ms or over some fixed delay. That way, you get new data every ms. Another workaround to the delay in receiving data is a technique called long polling. Long polling is more efficient than pinging the server repeatedly since it saves the hassle of parsing request headers, querying for new data, and sending often-empty responses. However, the server must now keep track of multiple requests and their order. Also, requests can time out, and new requests need to be issued periodically. However, SSE is not supported by older browsers, and most browsers limit the number of SSE connections you can make at the same time. So, we need a way to send information to the server, and receive updates from the server when updates come in. Enter WebSocket! Supported by almost all modern browsersthe WebSocket API allows us to open exactly that kind of two-way connection with the server. Moreover, the server can keep track of each client and push messages to a subset of clients. With this capability we can invite all of our friends to our chat app and send messages to all of them, some of them, or only your best friend. So, how exactly does this magic work? In the last section, we mentioned HTTP several times. HTTP is a protocola set of rules for how computers communicate on the web. WebSocket is another protocol for sending and receiving messages.

The WebSocket API (WebSockets)


The WebSocket API is an advanced technology that makes it possible to open a two-way interactive communication session between the user's browser and a server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply. Note: While a WebSocket connection is functionally somewhat similar to standard Unix-style sockets, they are not related. Get the latest and greatest from MDN delivered straight to your inbox.

Is there any way, to run 2 websockets at the same time, and a way to exchange clients between them? I mean for sending messages between those websockets. I have this implemented on my server, since I am using a cluster server each of my server is connected to each other all request coming to one server is automatically forwarded to the other server. Well, could you describe it more clearly, because it doesn't make for me any sense. Do you have a multiple websockets running on different ports, and there is possibility to send a message from one websocket to another? I didn't try such things, but can't you open a socket with React, and use that to communicate between the two WS server? NightShifter42 Do you mean 2 different servers clients can connect to or do you mean to load balance? I mean, I have one server. And two running websockets on different ports. So the clients of first socket, can interact send messages to clients of the second socket. If I have an already running websocket. And I'm trying to get clients from let's say like test. I'm new to php, so before I have worked with C. Could someone give me an idea, of how those clients can interact between two websockets? NightShifter42 You can run both WebSockets servers from one script. Checkout this issue which runs multiple servers bound to different IP addresses, you can use similar code to host different Apps bound to different ports. But I'm still don't know how can clients from different apps interact with each other? Maybe code tell you more. And how can I get all authenticated clients of WebSocketClients here, to send messages them from here??? You now have all the Connection objects in memory of one running application. You just need to bridge your 2 different app classes to share them. One way is to follow the architecture of Ratchet using decoration:. You then have one instance with all your connections pooled together and can route messages how ever you choose. Thanks for the great idea! Skip to content.
