MongoDB (Mongoose) persistence adapter & deployer for SAP CAP (works like @cap-js/hana / @cap-js/sqlite)

// lib/connection.js
const mongoose = require("mongoose");

let connected = false;

async function connect(uri, options = {}) {
  if (connected && mongoose.connection.readyState === 1) return mongoose.connection;

  if (!uri) throw new Error("MONGO_URL is required to connect to MongoDB");

  const defaultOpts = {
    // mongoose 7 removed useUnifiedTopology etc; keep flexible
    autoIndex: true
  };
  await mongoose.connect(uri, { ...defaultOpts, ...options });
  connected = true;
  console.log("[mongoose-cap-amo] Connected to MongoDB");
  return mongoose.connection;
}

function disconnect() {
  if (!connected) return Promise.resolve();
  return mongoose.disconnect().then(() => {
    connected = false;
  });
}

module.exports = { connect, disconnect, mongoose };
