How should this be done with MVC

I have an express.js application and I'm having problems wrapping my head around the MVC architecture. How can this code be separated into models and controllers? There are no views since it is an API.​server.jsconst express = require('express'); const bodyParser = require('body-parser'); const app = express(); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); require('./api/routes/order_routes.js')(app); const server = app.listen(process.env.PORT || 3001, () => { console.log('Listening on port %s...', server.address().port); }); order_routes.jsconst database = require('../models/database.js'); const db = new database.Database(); const orderRouter = (app) => { // Get all the orders from the database app.get('/api/v1/orders', (request, response) => { const query = 'SELECT id, order_items, status, amount, user_id, time FROM orders'; db.client.query(query) .then((res) => { if (res.rows) { response.status(200).json(res.rows); } else { response.status(200).json({ status: 'success', message: 'No orders yet' }); } }); }); }; module.exports = orderRouter; database.jsconst env = require('dotenv'); env.config(); const { Client } = require('pg'); class Database { constructor() { const config = { connectionString: process.env.DATABASE_URL, }; this.client = new Client(config); this.client.connect(); } } module.exports.Database = Database; The code works and all, I lifted snippets out of the whole thing but I want to know how I can seperate the code into models and controllers.
