import { createServer } from "http";
import { Low, Memory } from "lowdb";
import Adapter from "simple-odata-server-lowdb";
import ODataServer from "simple-odata-server";

const model = {
    namespace: "jsreport",
    entityTypes: {
        "UserType": {
            "_id": {"type": "Edm.String", key: true},
            "test": {"type": "Edm.String"},

            entityType: "jsreport.UserType"
        }
    }
};

const memoryDB = new Memory();
const db = new Low(memoryDB);
if (!db.data) {
  db.data = {};
  db.write();
}

const odataServer = ODataServer("http://localhost:1777");
odataServer
  .model(model)
  .adapter(Adapter(function (coll, cb) {
    if (!db.data[coll]) {
      db.data[coll] = [];
    }

    const hasPendingChanges = cb(null, db.data[coll]);
    if (hasPendingChanges) {
      db.write();
    }
  }));
  
createServer(odataServer.handle.bind(odataServer)).listen(1777);
