How to keep track of user on my app and know when he/she goes offline/online?

I am developing a simple chatting app with Mongoose (MongoDB) and NodeJS as my backend.

I have this Schema:

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const UserSchema = new Schema({
    name: {
        type: String,
        required: true
    },
    email: {
        type: String,
        required: true,
        unique: true
    },
    password: {
        type: String,
        required: true,
    },
    isActive: {
        type: Boolean,
        default: true,
    }
}, {timestamps: true});

My problem is how should I update if the user is offline? should I define some routes to change that or how should I do it, please?

I'm not sure if I designed the Schema correctly, especially the isActive field. you can suggest to me a better Schema as well.

Thank you so much as you help me out!!! 🙏🙏

You can do it using socket.io

Client-side you can fire emit with userId like

const socket = io();
socket.emit('online',{userId:'LoggedInUserId'});

Server-side

const onlineUsers = {};
io.on('connection', function(socket){
  socket.on('online', function(data){
    onlineUsers[socket.id] = data.userId;
    const doc = await User.findOneAndUpdate({
        id: data.userId
    }, { isActive: true }, { upsert: true });
  });

  socket.on('disconnect', function(){
    const oflineUserId = onlineUsers[socket.id];  
    const doc = await User.findOneAndUpdate({
        id: oflineUserId
    }, { isActive: false }, { upsert: true });
  });
});

Well you should create a middleware that will set the status into cache. Now define a function that will fetch the status of user from cache. And call this function in the parent layout.
