Supervisor SDK
The JavaScript library is a software client of the ProctorEdu proctoring system and can be used for integration with e-learning system.
How to use
An example of using with JWT authorization:
<script src="https://your-proctoring-server/sdk/supervisor.js"></script>
<script>
// create Supervisor instance
var supervisor = new Supervisor({ url: 'https://your-proctoring-server' });
// log in and initialize the session
supervisor
.init({
// set your provider name
provider: 'jwt',
// get JWT string from your server
token: fetch('/api/token').then(function(response) {
if (response.ok) return response.text();
else throw Error('Failed to get JWT');
})
})
.then(function() {
// start the session only after initialization
return supervisor.start();
})
.then(function() {
// start testing in the e-learning system here
})
.catch(function(err) {
// show alert with an error
alert(err.toString());
// redirect to home page
location.href = '/';
});
// stop the session after testing in the e-learning system is over,
// the timeout function is used here as an example
setTimeout(function() {
// stop the session
supervisor.stop()
.then(function() {
// log out the session
return supervisor.logout();
})
.then(function() {
// your action here after the successful completion of the session
});
}, 5 * 60 * 1000); // 5 minutes
</script>
Do not forget to change "your-proctoring-server" to your dedicated instance of the proctoring server.

Parameter | Minimum requirement |
---|---|
OS | Windows 7, macOS 10.12 "Sierra", Linux |

You should also consider the following limitations:
-
Your e-learning system must be hosted on a server with valid SSL certificate (via HTTPS protocol). Otherwise the video and audio capture will not work.
-
Your web page with SDK should not be fully reloaded while the library is running. For example, when switching between test questions. If the reload occurs in less than a minute, the proctoring results will not be saved.
