Information
What is this?
You can use this for any game / situation you would need a multiplayer-buzzer-system.
Anybody can create a new lobby, which can be used for others to join and buzz. There is always one host, who will see the order of buzzes and can reset the buzzing-state for each round.

How to host a lobby?
To create a new buzzing session ('lobby'), just click on 'Create a lobby'.
This will navigate you to the host-page of the newly created lobby.
Technical detail:
Note, that there is no real lobby-creation, only navigating to a url in the declared schema will open that lobby. So, basically, you can just navigate to '/host/{lobbyCode}' with your preferred lobby code.
A lobby does not need to be cleared / closed, once the host as well as all participants have closed the page, the lobby will destroy itself.

How to join / use as participant?
You either get shared a link or QR code from a host to a page where you only need to enter your nickname, or you can enter the lobby-code and nickname directly on the main page.
Once you've entered the nickname and joined the lobby, you will see the buzz-button. Once you buzz, our buzz wll be displayed to the host in the order all the participants buzzed. You can only buzz once until the host resets all buzzes again for the next round. The button will have a different color when you can buzz, and when you already buzzed.
Note, that once you close the page / connection is lost, the buzz for this round will be lost.

Which data is stored on the server?
The server will only have information you provided it. This includes exclusively the lobby-code, the nickname you entered, as well as potentially your IP address in server logs. The nickname and lobby-code will not be stored persistently, but may show up in application logs, which will be reset on application restart. While the application itself will not log your IP address, the server this application is hosted on may for monitoring / statistical reasons.
Stream / OBS Overlay?
Yes. Once you created the lobby, the host will see a 'Buzzes Overlay Link' in the bottom right corner, which navigates to a link you can use as OBS Browser source, which basically shows the part of the host view where you see who buzzed. As OBS browser source, enter 400 as width, and height to as much as you prefer to have displayed.
Can I host this on my own server / look at the source code?
Yes!
Have a look over at github.com/FlowMo7/kotlin-buzzer for the source code as well as how to host this on your own using docker.
