In the latest release of ably-js, we’ve added JSDoc comments for the public methods and properties provided by the SDK so you can quickly access the descriptions directly in your code editor using Intelligent code completion features like Intellisense in VSCode.

We have also implemented the fetch API as a fallback HTTP transport so that ably-js is now fully functional in a service worker context.

How do I give feedback?
This docs update and further planned changes are based on feedback from customers like you. So if you’d like to share any other requests or feedback, please reach out to us and help us make Ably better for everyone.
