ReLet's start by initializing the client.

const CoreClient = require("rtcfly").client; 
const core = new CoreClient();

call

Use this method to call another user.

core.call({
    id:"targetID", //Unique identifier for the target user
    localElement:HTMLMediaElement,  //the video element for the caller
    remoteElement:HTMLMediaElement, //the video element for the callee
    audio:true, //request audio stream
    video:true //request video stream
});

This will get the users media streams, ie video, audio, screen share.

After the RTCFly core is initialized, the callInitialized event will be triggered with all of the above parameters.

answerCall

Like "call", this method will take a load of parameters to intialize the session

core.answerCall({
    localElement:HTMLMediaElement,  //the video element for the callee
    remoteElement:HTMLMediaElement, //the video element for the caller
    audio:true, //request audio stream
    video:true //request video stream
});

rejectCall

core.rejectCall();

This will simply trigger a callRejected event on the caller's side and cancel the session.

endCall

core.endCall();

This will trigger a callTerminated event on both clients.
