To listen to realtime events on the client (browser), you can use the frappe.realtime.on method:

frappe.realtime.on('event_name', (data) => {

To publish a realtime event from the server, you can use the frappe.publish_realtime method:

frappe.publish_realtime('event_name', data={'key': 'value'})


You can use this method to show a progress bar in a dialog:

frappe.publish_progress(25, title='Some title', description='Some description')
