What is the right way to make a synchronous MongoDB query in Node.js?

Question

I\'m using the Node.JS driver for MongoDB, and I\'d like to perform a synchronous query, like such:

function getAThing()
{
    var db = new mongo.Db(\"mydata

ES 6 (Node 8+)

You can utilize async/await

await operator pauses the execution of asynchronous function until the Promise is resolved and returns the value.

This way your code will work in synchronous way:

const query = MySchema.findOne({ name: /tester/gi });
const userData = await query.exec();
console.log(userData)

Older Solution - June 2013 ;)

Now the Mongo Sync is available, this is the right way to make a synchronous MongoDB query in Node.js.

I am using this for the same. You can just write sync method like below:

var Server = require("mongo-sync").Server;
var server = new Server('127.0.0.1');
var result = server.db("testdb").getCollection("testCollection").find().toArray();
console.log(result);

Note: Its dependent on the node-fiber and some issues are there with it on windows 8.

Happy coding :)
