WebSocket

A WebSocket is a high-performance communication protocol (standardised in RFC 6455) that creates a persistent, bi-directional connection between a browser and server. It is the underlying technology behind real-time features like live dashboards, instant messaging, and collaborative tools: users see updates at the same moment they happen, and users don't need to refresh the page.

Unlike the classical HTTP request-response model, where a browser asks, the server answers, and the connection closes, WebSocket keeps a persistent TCP connection open, allowing the server to push data to the client the instant it becomes available.

In the standard web model (HTTP), a browser asks the server for new information, receives it, and then hangs up. A WebSocket keeps a "live line" open that allows the server to push data to the user at the exact moment it becomes available. The user doesn’t need to refresh their page or have the browser send a request.

Industry Context: Real-Time Experiences

• Media and streaming services: platforms like Twitch or YouTube Live use WebSockets to power live chat, real-time polls, and viewer reactions. This allows situations where creators ask questions, and the audience's response is seen by everyone at the same moment.
• Collaborative tools: software, like Figma or Google Docs, uses WebSockets, which allows a co-working experience: for instance, when one teammate moves a cursor or types a word, all other teammates see the result instantly.

Value for Social and Community Integration

For platforms using Watchers’ social tools, WebSocket is the engine behind active user retention, because communities feel alive only when interaction is instantaneous.

• Seamless сommunity сhat: when a user sends a message in a widget, WebSockets deliver it to every other participant in real time without the artificial delays introduced by polling intervals. This "instant-reply" environment mimics face-to-face conversation.
• Presence indicators: features like “user counter” are powered with WebSockets. These small social cues are proven to increase the likelihood of a user staying on the page to continue a conversation.
• Live engagement triggers: Watchers use WebSockets to push “new reaction,” "new messages," and many other events in the moment they happen. By delivering these pings in real-time, we help clients drive higher Daily Active Users (DAU).
