Establishing a Connection

This feature allows you to establish a connection to a server that sends events. The code sample demonstrates how to create a new EventSource instance and listen for incoming messages.

const EventSource = require('@sanity/eventsource');
const es = new EventSource('http://example.com/events');
es.onmessage = function(event) {
  console.log('New message:', event.data);
};

Handling Different Event Types

This feature allows you to listen for specific types of events sent by the server. The code sample shows how to add an event listener for a custom event type.

const EventSource = require('@sanity/eventsource');
const es = new EventSource('http://example.com/events');
es.addEventListener('customEvent', function(event) {
  console.log('Custom event received:', event.data);
});

Handling Connection Errors

This feature allows you to handle errors that occur during the connection. The code sample demonstrates how to set up an error handler for the EventSource instance.

const EventSource = require('@sanity/eventsource');
const es = new EventSource('http://example.com/events');
es.onerror = function(event) {
  console.error('Error occurred:', event);
};
