我现在有一个脚本，它使用LocalStorage作为我的Haxball房间：https://www.haxball.com/play

class HaxStatistics {
    constructor(playerName = '') {
        this.playerName = playerName;
        this.games = 0;
        this.wins = 0;
        this.winrate = '0.00%';
        this.playtime = 0;
        this.goals = 0;
        this.assists = 0;
        this.CS = 0;
        this.ownGoals = 0;
    }
}

function globalStatsCommand(player, message) {
    var stats = new HaxStatistics(player.name);
    if (localStorage.getItem(authArray[player.id][0])) {
        stats = JSON.parse(localStorage.getItem(authArray[player.id][0]));
    }
    var statsString = printPlayerStats(stats);
    room.sendAnnouncement(
        statsString,
        player.id,
        infoColor,
        'bold',
        HaxNotification.CHAT
    );
}

function statsLeaderboardCommand(player, message) {
    var key = message.split(/ +/)[0].substring(1).toLowerCase();
    printRankings(key, player.id);
}

function updatePlayerStats(player, teamStats) {
    var stats = new HaxStatistics(player.name);
    var pComp = getPlayerComp(player);
    if (localStorage.getItem(authArray[player.id][0])) {
        stats = JSON.parse(localStorage.getItem(authArray[player.id][0]));
    }
    stats.games++;
    if (lastWinner == teamStats) stats.wins++;
    stats.winrate = ((100 * stats.wins) / (stats.games || 1)).toFixed(1) + `%`;
    stats.goals += getGoalsPlayer(pComp);
    stats.assists += getAssistsPlayer(pComp);
    stats.ownGoals += getOwnGoalsPlayer(pComp);
    stats.CS += getCSPlayer(pComp);
    stats.playtime += getGametimePlayer(pComp);
    localStorage.setItem(authArray[player.id][0], JSON.stringify(stats));
}

function updateStats() {
    if (
        players.length >= 2 * teamSize &&
        (
            game.scores.time >= (5 / 6) * game.scores.timeLimit ||
            game.scores.red == game.scores.scoreLimit ||
            game.scores.blue == game.scores.scoreLimit
        ) &&
        teamRedStats.length >= teamSize && teamBlueStats.length >= teamSize
    ) {
        for (let player of teamRedStats) {
            updatePlayerStats(player, Team.RED);
        }
        for (let player of teamBlueStats) {
            updatePlayerStats(player, Team.BLUE);
        }
    }
}

function printRankings(statKey, id = 0) {
    var leaderboard = [];
    statKey = statKey == "cs" ? "CS" : statKey;
    for (var i = 0; i < localStorage.length; i++) {
        var key = localStorage.key(i);
        if (key.length == 43)
            leaderboard.push([
                JSON.parse(localStorage.getItem(key)).playerName,
                JSON.parse(localStorage.getItem(key))[statKey],
            ]);
    }
    if (leaderboard.length < 5) {
        if (id != 0) {
            room.sendAnnouncement(
                'Non ci sono ancora abbastanza partite giocate!',
                id,
                errorColor,
                'bold',
                HaxNotification.CHAT
            );
        }
        return;
    }
    leaderboard.sort(function (a, b) { return b[1] - a[1]; });
    var rankingString = `${statKey.charAt(0).toUpperCase() + statKey.slice(1)}> `;
    for (let i = 0; i < 5; i++) {
        let playerName = leaderboard[i][0];
        let playerStat = leaderboard[i][1];
        if (statKey == 'playtime') playerStat = getTimeStats(playerStat);
        rankingString += `#${i + 1} ${playerName} : ${playerStat}, `;
    }
    rankingString = rankingString.substring(0, rankingString.length - 2);
    room.sendAnnouncement(
        rankingString,
        id,
        infoColor,
        'bold',
        HaxNotification.CHAT
    );
}

由于LDB files不可读，它的最大空间为5mb，由于经济原因，我目前无法使用数据库，我想读取位于我的AWS VPS中的本地JSON file。我通过找到这个documentation找到了FileReader的可能解决方案，并尝试了这个解决方案：

let reader = new FileReader();
reader.readAsText("/home/haxroomie/stats.json");
console.log(reader.result)

不幸的是，它给了我一个错误，我不知道如何移动了...建议？
小澄清：我要打开的文件在我的AWS VPS
