// Example
var es = new Instantly('http://your-sse-endpoint.codes/channel', {
    origin: 'http://your-sse-endpoint.codes', // Optional. Just an extra level of precaution to verify your event origin matches your app's origin.
    retries: 2, // Optional. Default: 5 retries if connection to your endpoint fails.
    timeout: 1000, // Optional. Default: 15 seconds (15000). This is how often we should retry.
    closeConnNotFocus: true, // Optional. Default: false. This will close the SSE connection if the tab/window is not in focus. Will reconnect when in focus.
    error: function(err) {
        console.log(err);
    }, // Optional. Extending the internal error handler.
    open: function(event) {
        console.log(event);
    }, // Optional. Extend when you open a connection to SSE.
    close: function() {
        console.log('closed');
    }, // Optional. Extend when a connection to SSE is closed. (Usually when an error occur)
    injectEventSourceNode: require('eventsource'), // Optional. If the module is being used in Node you're able to inject [eventsource-node](https://www.npmjs.com/package/eventsource)
});

// If you want to use default options
// var es = new Instantly('http://your-sse-endpoint.codes/channel');

// Listen to messages without any event set

// Start to listen for events send by SSE
es.listen();

// Close
es.close();

// Need to open the connection again?
es.listen();
