scoreboard-lib

Example Node.js library for handling Scoreboard's games. It offers 4 different operations:

• start : starts a game by passing home and away teams & returns gameId. Sets a score to 0 - 0
• update : update a game score by passing gameId and actual score
• finish : finish a game by passing gameId. Game is removed from storage
• getAllGames : returns all ongoing games orderd by score and game's start time

how to use the library

Scoreboard library is a npm module which can be installed locally

npm i scoreboard-lib

If you have a typescript project this is an example usage

import { 
    GameRepositoryImpl, 
    GameRepository,
    ScoreBoardImpl,
    ScoreBoard,
    Team, 
    TeamType 
} from 'scoreboard-lib';

const repo: GameRepository = new GameRepositoryImpl();
const scoreboard: ScoreBoard = new ScoreBoardImpl(repo);

const firstTeamHome: Team = { city: "xxx", name: 'Manchester', type: TeamType.HOME};
const firstTeamAway: Team = { city: "yyy", name: 'Liverpool', type: TeamType.AWAY};
const firstGameId: string = scoreboard.start(firstTeamHome, firstTeamAway);

scoreboard.update(firstGameId,7,0);

const secondTeamHome: Team = { city: "xxx", name: 'Barcelona', type: TeamType.HOME};
const secondTeamAway: Team = { city: "yyy", name: 'Real', type: TeamType.AWAY};
const secondGameId: string = scoreboard.start(secondTeamHome, secondTeamAway);

scoreboard.update(secondGameId,3,1);

scoreboard.getAllGames().map( game => {
    console.log(`${game}`);
});

Generally to use a scoreboard-lib module you need to create a game repository first

const repo: GameRepository = new GameRepositoryImpl();

and create a score board passing the game repository to the constructor

const scoreboard: ScoreBoard = new ScoreBoardImpl(repo);

The intention of game repositpory is to create a data layer allowing different storage types in future.
