Web Bluetooth hybrid API

Hi group,

we've been following the web-bluetooth specification closely with interest and with a view to implementing it as an abstraction interface over other popular JavaScript-BLE implementations on web, server and mobile.

We are aware this is a web-bluetooth specification rather than JavaScript-bluetooth, however it does rely heavily on the use of ES6 promises, a paradigm not commonly used on many platforms (yet!).

Promises are an elegant approach to asynchronous programming, but even in web development the use of promises could perhaps be considered a choice of the developer and not forced by the API.

We were wondering if a hybrid approach was considered when defining the specification which allows the choice of using promises (if available) or a callback with an error object.

Examples of this approach can be seen in these npm modules:

https://www.npmjs.com/package/hybridify
https://www.npmjs.com/package/handle-callback

Forgive my ignorance if discussions around this are already public.


Kind regards,

Rob
