如何在discord.js中用JSON数据库制作排行榜

{
  "leaderboard": [
    {"user": "User1", "score": 100},
    {"user": "User2", "score": 80},
    {"user": "User3", "score": 60}
  ]
}

const fs = require('fs');

function updateLeaderboard(data) {
  fs.writeFileSync('database.json', JSON.stringify(data, null, 2));
}

function getLeaderboard() {
  const data = fs.readFileSync('database.json');
  return JSON.parse(data);
}

client.on('message', message => {
  if (message.content === '!leaderboard') {
    const leaderboard = getLeaderboard().leaderboard;
    let response = '排行榜：\n';

    leaderboard.forEach((entry, index) => {
      response += `${index + 1}. ${entry.user} - ${entry.score}\n`;
    });

    message.channel.send(response);
  }
});

client.on('message', message => {
  if (message.content.startsWith('!updateScore')) {
    const args = message.content.split(' ');
    const user = args[1];
    const score = parseInt(args[2]);

    const leaderboard = getLeaderboard().leaderboard;
    const existingEntry = leaderboard.find(entry => entry.user === user);

    if (existingEntry) {
      existingEntry.score += score;
    } else {
      leaderboard.push({ user, score });
    }

    leaderboard.sort((a, b) => b.score - a.score);
    updateLeaderboard({ leaderboard });

    message.channel.send(`已更新 ${user} 的分数为 ${score}`);
  }
});
