You can use Jitsi Meet API to create Jitsi Meet video conferences with a custom GUI.
NOTE: you need Node.js >= 12 and npm >= 7
To build the library, just type:
npm install npm run build
npm run lint
and to run unit tests:
if you need to rebuild lib-jitsi-meet.min.js
npm run build
Both linting and units will also be done by a pre-commit hook.
