node.js - 当新的月份到来时，如何创建一个新文件夹并在那里写入新日志？

Question

每天都会创作一些杂志。如何确保当新的月份到来时，创建一个文件夹并将所有日志写入其中。每次新的一个月到来时都是如此。

function formatDate(date) {
    var monthNames = [
        "January", "February", "March",
        "April", "May", "June", "July",
        "August", "September", "October",
        "November", "December"
    ];
    var day = date.getDate();
    var monthIndex = date.getMonth();
    var year = date.getFullYear();
    return day + '_' + monthNames[monthIndex] + '_' + year;
}

function formatTime(time) {
    var hours = time.getHours();
    var minutes = time.getMinutes();
    var seconds = time.getSeconds();
    return hours + '_' + minutes + '_' + seconds;
}

var ws = fs.createWriteStream(`./logs/file-${formatDate(new Date())}-${formatTime(new Date())}.log`, {
    'flags': 'w',
    'encoding': 'utf8'
});

process.stdout.wr = process.stdout.write;
process.stdout.er = process.stderr.write;

process.stdout.write = function (mes, c) {
    ws.write(mes + '\r\n');
    process.stdout.wr(mes, c);
};

process.stderr.write = function (mes, c) {
    ws.write(mes + '\r\n');
    process.stdout.er(mes, c);
};

如果你想知道如何在每个特定时间执行一个函数，我可以推荐你 npm 包later.js。如果您的代码有问题，请更好地为其他用户写下您的问题
