# omniobserver
NOTE: Chrome debugger will show detailed call stack.
Example observing WebRTC and the event listener on RTCPeerConnection.
```typescript
/** will observe getUserMedia and RTCPeerConnection */
export function observeWebRTC() {
observeObjectProperty(navigator.mediaDevices, "getUserMedia");
observeObjectProperty(window, "RTCPeerConnection", (rtcPeerConnection: RTCPeerConnection) => {
console.log(rtcPeerConnection);
if( !!rtcPeerConnection.getStats ){
setTimeout(()=>{
rtcPeerConnection.getStats().then(
stats=> {
const arr: any[]= [];
stats.forEach(o => {
console.log(JSON.stringify(o));
arr.push(o);
});
console.log("<======>");
console.log(JSON.stringify(arr));
}
);
},20000);
}
const {
addEventListener: addEventListenerBackup,
removeEventListener: removeEventListenerBackup
} = rtcPeerConnection;
const proxyByOriginal = new WeakMap();
Object.defineProperties(
rtcPeerConnection,
{
"addEventListener": {
"configurable": true,
"enumerable": true,
"value": function addEventListener(type: string, listener: Function) {
const listenerProxy = function (...args) {
console.log(`RTCPeerConnectionEvent: "${type}"`, args);
return listener.apply(rtcPeerConnection, args);
};
proxyByOriginal.set(listener, listenerProxy);
return addEventListenerBackup.call(rtcPeerConnection, type, listenerProxy);
}
},
"removeEventListener": {
"configurable": true,
"enumerable": true,
"value": function removeEventListener(type: string, listener: Function) {
return removeEventListenerBackup.call(rtcPeerConnection, type, proxyByOriginal.get(listener));
}
}
}
);
});
}
