How to connect with Mongodb with Nodejs and fetching data?

Hello to all, welcome to therichpost.com. In this post, I will tell you, How to connect with Mongodb with Nodejs and fetching data?

MongoDB is NoSQL database. Now I am learning this and this is very interesting and I am going to share some working examples.

We can also save the mongodb data into custom json file and this feature makes mongodb better.

Mongodb data with command prompt query:

Here is the working coding steps you need to follow:

1. First you need to run below query to install mongodb into your node app:

$ npm install mongodb

2 . Here is the code you need to add into testcode.js(you can choose you name) file:

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";
MongoClient.connect(url, function(err, db) {
  if (err) throw err;
  var dbo = db.db("test");
  dbo.collection("test").findOne({}, function(err, result) {
    if (err) throw err;
    console.log(result.Field);
    db.close();
  });
});

3. After this, run below command into your terminal and see the output:

$ node testcode.js

Now this is it, if you have any query related to this post then do comment below or ask question.
