如何在 JavaScript 中包含多个文件夹？

Question

I'm trying to include multiple folders in JavaScript, specific: Discord JS, here's my code:

const commandFiles = fs.readdirSync('./aPublic').filter(file => file.endsWith('.js')); // I wanted to include it here

for (const file of commandFiles) {
    const command = require(`./aPublic/${file}`); // I wanted to include it here too!
    client.commands.set(command.name, command);
}

I've tried to use ./aPublic &&./bAdmin and also ('./aPublic') && ('./bAdmin') but it only read the "bAdmin" folder rather than both of them, I wanted to include like 7 folders in both code.

Let's put your list of directories in an array like below, use .map() to read each of them, join the path of each file with its corresponding directory and flatten the result using .flat() .

const arrDir = ['./aPublic', './bPublic'];

const commandFiles = arrDir
    .map(dir => {
        const listFiles = fs.readdirSync(dir);
        return listFiles.map(file => path.join(__dirname, dir, file));
    })
    .flat()
    .filter(file => file.endsWith('.js'));

for (const file of commandFiles) {
    const command = require(file);
    client.commands.set(command.name, command);
}
