Assist

OpenReplay Assist allows you to support your users by seeing their live screen and instantly hopping on call (WebRTC) with them without requiring any 3rd-party screen sharing software.

Installation

npm i @openreplay/tracker-assist

Usage

With JavaScript snippet

If your OpenReplay tracker is set up using the JS snippet, then simply replace the .../openreplay.js occurrence with .../openreplay-assist.js. Below is an example of how the script should like after the change:

<!-- OpenReplay Tracking Code -->
<script>
var initOpts = { projectKey: "GxPpaDARdn2345fgt321" };
var startOpts = { userID: "" };
(function(A,s,a,y,e,r){
r=window.OpenReplay=[e,r,y,[s-1, e]];
s=document.createElement('script');s.src=A;s.async=!a;
...
})("//static.openreplay.com/latest/openreplay-assist.js", 1, 0, initOpts, startOpts);
</script>

With NPM

Initialize the tracker then load the @openreplay/tracker-assist plugin.

If your website is a Single Page Application (SPA)

import Tracker from '@openreplay/tracker';
import trackerAssist from '@openreplay/tracker-assist';
const tracker = new Tracker({
projectKey: PROJECT_KEY,
});
tracker.use(trackerAssist(options)); // check the list of available options below
tracker.start();

If your web app is Server-Side-Rendered (SSR)

Follow the below example if your app is SSR. Ensure tracker.start() is called once the app is started (in useEffect or componentDidMount).

import OpenReplay from '@openreplay/tracker/cjs';
import trackerFetch from '@openreplay/tracker-assist/cjs';
const tracker = new OpenReplay({
projectKey: PROJECT_KEY
});
tracker.use(trackerAssist(options)); // check the list of available options below
//...
function MyApp() {
useEffect(() => { // use componentDidMount in case of React Class Component
tracker.start();
}, [])
//...
}

Options

trackerAssist({
callConfirm?: string|ConfirmOptions;
controlConfirm?: string|ConfirmOptions;
config?: object;
onAgentConnect?: () => (()=>void | void);
onCallStart?: () => (()=>void | void);
onRemoteControlStart?: () => (()=>void | void);
})
type ConfirmOptions = {
text?:string,
style?: StyleObject, // style object (i.e {color: 'red', borderRadius: '10px'})
confirmBtn?: ButtonOptions,
declineBtn?: ButtonOptions
}
type ButtonOptions = HTMLButtonElement | string | {
innerHTML?: string, // to pass an svg string or text
style?: StyleObject, // style object (i.e {color: 'red', borderRadius: '10px'})
}
  • callConfirm: Customize the text and/or layout of the call request popup.
  • controlConfirm: Customize the text and/or layout of the remote control request popup.
  • config: Contains any custom ICE/TURN server configuration. Defaults to { 'iceServers': [{ 'urls': 'stun:stun.l.google.com:19302' }], 'sdpSemantics': 'unified-plan' }.
  • onAgentConnect: () => (()=>void | void): This callback function is fired as soon as a live session starts. It can also return onAgentDisconnect which will be called when the session is disconnected. In case of an unstable connection, this may be called several times. Below is an example:
onAgentConnect = () => {
console.log("Live session started")
const onAgentDisconnect = () => console.log("Live session stopped")
return onAgentDisconnect
}
  • onCallStart: () => (()=>void | void): This callback function is fired as soon as a call (webRTC) starts. It can also return onCallEnd which will be called when the call ends. In case of an unstable connection, this may be called several times. Below is an example:
onCallStart: () => {
console.log("Call started")
const onCallEnd = () => console.log("Call ended")
return onCallEnd
}
  • onRemoteControlStart: () => (()=>void | void): This callback function is fired as soon as a remote control session starts. It can also return onRemoteControlEnd which will be called when the remote control permissions are revoked. Below is an example:
onCallStart: () => {
console.log("Remote control started")
const onCallEnd = () => console.log("Remote control ended")
return onCallEnd
}
