Bingo for meetings– working at sharing meeting with others–part 4

Bingo is a small project, written in TypeScript , and developed with Alexandru Badita in launch break (one hour - more or less). You can find sources at https://github.com/alexandru360/PresentationBingoCards/ . Those are my blog posts for Bingo : ( scroll below for the post)

(Now the actual blog post for Bingo Meetings project)

Other use case for Bingo Meetings was Share meeting bingo(https://github.com/alexandru360/PresentationBingoCards/projects/1#card-24165765)

Share Meeting Bingo:

As a User, I can receive the meeting Id( url) . When going to this url , I can ( optionally) enter my name and check cards.

So how to implement this  ? A Meeting contains an array of Cards and a array of Participants. How a Participant can check cards ?

There are several solutions for this:

  1. The Participant can have an Id of the meeting, is going to some form of database( even in memory , like a singleton collection of Meetings), retrieve the meeting, retrieve the cards, check the card
  2. The participant raise an event ( PleaseCheckThisCardForMe) , the meeting listens and checks the meeting
  3. The participant have a real reference of the cards and checks the cards
  4. The meeting has a  CheckCardByParticipant that someone can call ( leaving the responsibility later  – maybe on API )

We ( me and Alexandru Badita we have choosed the latest solution. So we came with the following :


public CheckCardByParticipant(c: Cards , p:Participant){
        //TODO: verify participant is added first or add
        //TODO: verify card is added first
        c.CheckMe(p);
    }

and a test


import  MeetingsFactory from '../MeetingsFactory';
import Meeting from '../meeting';
describe('Check  card basic', () => {
    it('card should be checked', () => {
        const mf=new MeetingsFactory();
        const m1=mf.CreateMeeting("andrei","first meeting");
        console.log(m1.Cards.length);
        
        expect(m1.AllUnchecked()).toBe(true);
        m1.CheckCardByParticipant(m1.Cards[0], m1.Participants[0]);    
        expect(m1.AllUnchecked()).toBe(false);
        expect(m1.IsCardCheckedByParticipant(m1.Cards[0], m1.Participants[0])).toBe(true);
        
        
  
      })
    
  })
  

Obviously, from TODO, we have to put more code and more tests – but for the moment we think that nobody will want to break our application on purpose….
