Issue Resolved / Feature Added

webos/LS2Request provides a class for making LS2 service request.
It would be better to support the developer to request LS2 request with a promise

Resolution

LS2Request.send is a method to request luna call to a webos app or service.
So send method with promise is what developers need.
To provide LS2Request.send as a promise, I add a new function: sendLS2Request
sendLS2Request returns a promise which run LS2Request.send.
This promise will be resolved when send successes, and will be rejected when send fails.
So developers can use their own onSuccess and onFailure after the promise is resolved or rejected.

Additional Considerations

I tried to make a new function as a react custom hook where useEffect is combined with sendLS2Request so that developers can use it more easily.
However, I couldn't because onSuccess and onFailure functions both should be given in a component and should be in useEffect hook.
I think it's better for developers to choose use useEffect or not in a component case by case.
