// app.js

const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const cors = require('cors');

const app = express();

const User = require('./models/User');

app.use(bodyParser.json());
app.use(cors());

mongoose.connect('mongodb://localhost/myDatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => {
    console.log('Connected to database');
  })
  .catch(() => {
    console.log('Connection failed');
  });

app.get('/users', (req, res) => {
  const pageSize = 10; // Number of items per page
  const currentPage = req.query.page || 1; // Current page number, default to 1

  User.find()
    .skip((pageSize * currentPage) - pageSize) // Skip items based on page number
    .limit(pageSize) // Limit items to page size
    .then(users => {
      res.status(200).json({
        message: 'Users fetched successfully',
        users: users
      });
    })
    .catch(error => {
      res.status(500).json({
        message: 'Fetching users failed',
        error: error
      });
    });
});
