navigator.mediaDevices is exposed to secure contexts only. This means your website needs to be served over HTTPS, not HTTP. — François Beaufort

You need to be on https:// or localhost for navigator.mediaDevices to be available.

For security purposes, accessing mediaDevices on http:// is not allowed. Therefore, you receive an error that it cannot find the fuction enumerateDevices, because indeed, mediaDevices is undefined.

Solutions, from easy to hard:

Use localhost as your development server.
Tunnel your local server using a tool such as ngrok or localtunnel, which will act as a https to http proxy.
Upload your app to a server supporting https.
Add SSL certificates to your development server, and access using https://.
