How to include multiple folder in JavaScript?

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.

Have you tried path.join(__dirname, './aPublic/') for readdirSync path? const path = require("path"); — HVD

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);
}

@Zhxck I have some errors in the for loop above. Give me a few seconds to correct them.

I've just updated the code. Basically we need to join the path first before filtering them.
