How to create a MongoDB Array and use it on node.js?

I am creating a Discord Bot, this is a problem I faced when I try to create an Array of data for MongoDB.

I don’t have a bigger knowledge of MongoDB. So actually I don’t know how to work with MongoDB arrays.

CountersSchema.js

const {Schema, model} = require('mongoose');

const countersSchema = new Schema({
    Guild: { type: String, required: true },
    Counters: [
        {
            Names: { type: String, required: true },
            Types: { type: String, required: true },
            Channels: { type: String, required: true }
        }
    ]
});

module.exports = model(`counters`, countersSchema);

I tried to create an array in here. I’m not sure whether this is correct or wrong.

The thing I want to do is, let users create counters for their Discord servers. And I want them to only allow max 5 counters per server. So I created this schema to store that data for each counter they create.

I want this Guild value to be unique. which is the id of the server. And I want Names , Types & Channels to be an arrays of up to 5 values and falls under the Guild value.

Counters.js

const counterChannels = require('../../Schemas/CountersSchema');

const data = async (interaction) => {
    try {
        return await counterChannels.findOne({ Guild: interaction.guild.id });
    } catch (error) {
        console.error('Error while fetching counters:', error);
        return null;
    }
};

const existingCounter = await data(interaction);

if (existingCounter) {
    // Check if the maximum number of counters is reached
    if (existingCounter.Counters.length >= 5) {
       return;
    };

    await counterChannels.updateOne(
    { Guild: guild.id },
    {
        $push: {
        Counters: {
            Names: givenName, // givenName Declaration not included.
            Types: counterType, // counterType Declaration not included.
            Channels: createdCounter.id // createdCounter Declaration not included.
        }
        }
    }
    );

} else {
    await counterChannels.create({
    Guild: guild.id,
    Counters: [{
        Names: givenName,
        Types: counterType,
        Channels: createdCounter.id
    }]
    });
}

This is only a part of the Counters.js file. This is how I tried to find if there are any previous data is available in the db.
And if no data available, I want to create a new entry under the guild id and assign these 3 values to that array.
If previous data available, I only want to assign new values to the array and keep the Guild as it is.

So, I want your help in here to correctly do this. I don’t think I have done this correctly.

There is one more thing. That is how to call the data using the array.

ServerCounters.js

const serverCounters = require('../Schemas/CountersSchema');

async execute (member) {
   const data = await serverCounters.find({Guild: member.guild.id});
   if(!data.length) return;

   const counterType = data.map(doc => doc.Types);
   const counterChannel = data.map(doc => doc.Channels);
   const counterName = data.map(doc => doc.Names);
}

in this code, I want to check is there counter data available for the server. just like the previous Counters.js file. After that, I want to devide the data according to the values of Types. So let’s say if one of the values in Types array is 'Total Members', then I want to get the values of the other two arrays that are included along with the 'Total Members' for Types.

So, this is what I’m looking for the help with.

• Create 3 arrays with up to 5 different values. Named Types , Names , and Channels under the Guild.
• Check if there are already 5 values for that 3 arrays under the interacting guild’s id. (in Counters.js)
• If no data available, create new entry for that guild.
• If less than 5 values available, insert current data to that 3 arrays also.
• Find corresponding values of the Names and Channels arrays using values of Types array.
