An EventSource is a web API that allows a web page to receive real-time updates from a server. It establishes a persistent connection between the web page and the server, enabling the server to send events to the web page whenever new data is available.

To use EventSource, you need to create a new instance of the EventSource object in JavaScript. You provide the URL of the server endpoint that will be sending the events as the parameter to the EventSource constructor.

Once the connection is established, the server can send events to the web page using the EventSource API. These events can be in any format, such as JSON or plain text. The web page can then handle these events using event listeners.

EventSource also supports automatic reconnection in case the connection is lost. It will attempt to reconnect to the server and resume receiving events.

Overall, EventSource is a useful tool for building real-time web applications that require continuous updates from the server without the need for constant polling.
