HMSActions<T>

The below interface defines our SDK API Surface for taking room related actions. It talks to our 100ms backend and handles error reconnections, state managements and lots of other things so you don't have to. You can use this gateway with any sort of UI to make connecting to our backend easier. In case you use React, we also provide a HMSProvider class with very powerful hooks and out of box components which you can use to set up your website in minutes. Our components have in built integration with this interface, and you won't have to worry about passing props if you use them.

Remarks

There is a one to one mapping between an instance of this class and a 100ms room, in case you're creating multiple rooms please create new instance per room.
