Compatibility and Requirements

CalendarService is a JavaScript module that provides an API to Lightning web components to make mobile hardware and platform (operating system) features available in JavaScript. It requires access to device hardware and device platform APIs. This access is only available when CalendarService runs within a compatible Salesforce mobile app. It does not and cannot function when running in a standard web browser, whether the browser runs on a desktop or mobile device. 

CalendarService is available in Lightning apps distributed using:

  • Mobile Publisher for Experience Cloud

CalendarService is fully functional when used in a Lightning app run from a compatible Salesforce mobile app on a compatible iOS or Android mobile device. See Requirements for Mobile Publisher for Experience Cloud or the requirements page for your target mobile app for specific device and operating system requirements.

CalendarService is not fully functional when running on other devices, such as a desktop, or when running in a web browser, even on a mobile device. It requires one of the mobile apps listed above. The CalendarService API is accessible in Lightning Experience on all devices, so your code won’t fail due to missing functions. However, when your app runs in a browser–desktop or mobile–it can use only CalendarService constants and utility functions. Attempting any calendar-related operation will fail.
