# Mongoose doc


Firstly, We will try to understand .. 

What is MongoDB?


MongoDB is a source-available cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.
 For more details Documents here!




 Now, You will understand something called Mongoose? ... 


Mongoose is a Javascript  object-oriented programming library that creates a connection between MongoDB and the Node-js JavaScript runtime environment.



 The following functions are used on the Document of the Mongoose:



Retrieving: The document is retrieved by different model functions like findOne(), findById().


const doc = MyModel.findById(myid);



Saving: The document is saved by calling the save function. The function is asynchronous and should be awaited.


await doc.save()



Updating using save(): The document can be updated by the save() function as follows:


await MyModel.deleteOne({ _id: doc._id });



doc.firstname = 'Manish';


await doc.save();



Updating using queries: The document can be updated by the queries without calling the save function.


await MyModel.findByIdAndUpdate(myid,{firstname: 'Manish'},function(err, docs){});



Let understand after combinating all above function in one example:



 We will be using node.js for this example. Node.js and npm should be installed.



Step 1: Create a folder and initialize it:


npm init



Step 2: Install mongoose in the project.


npm i mongoose



The project structure is as follows:

Step 3: Create a file called index.js. Inside the index.js, connect to MongoDB. Here the MongoDB Compass is used.

Step 4: Now run the code using the following command in the Terminal/Command Prompt to run the file.


node index.js

And the document in the MongoDB is as follows:
