# Qt WebSockets

WebSocket is a web-based protocol designed to enable two-way communication between a client application and a remote host. It enables the two entities to send data back and forth if the initial handshake succeeds. WebSocket is the solution for applications that struggle to get real-time data feeds with less network latency and minimum data exchange.

The Qt WebSockets module provides C++ and QML interfaces that enable Qt applications to act as a server that can process WebSocket requests, or a client that can consume data received from the server, or both.

## Getting Started

To include the definitions of the module's classes, use the following directive:

      #include <QtWebSockets/QtWebSockets>

To import the QML types into your application, use the following import statement in your .qml file:

      import QtWebSockets 1.0

To link against the module, add this line to your qmake .pro file:

      QT += websockets
