Prettyprint in MongoDB shell as default?

You can call pretty() function on cursor object to prettyprint in MongoDB shell. The syntax is as follows −

db.yourCollectionName.find().pretty();

To understand the concept, let us create a collection with the document. The query to create a collection with a document is as follows −

>db.prettyDemo.insertOne({"ClientName":"Larry","ClientAge":27,"ClientFavoriteCountry":["US","UK"]});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5c8a440de01f572ca0ccf5f2")
}
>db.prettyDemo.insertOne({"ClientName":"Mike","ClientAge":57,"ClientFavoriteCountry":["AUS","UK"]});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5c8a4420e01f572ca0ccf5f3")
}

Display all documents from a collection with the help of find() method. The query is as follows −

> db.prettyDemo.find();

The following is the output −

{ "_id" : ObjectId("5c8a440de01f572ca0ccf5f2"), "ClientName" : "Larry", "ClientAge" : 27, "ClientFavoriteCountry" : [ "US", "UK" ] }
{ "_id" : ObjectId("5c8a4420e01f572ca0ccf5f3"), "ClientName" : "Mike", "ClientAge" : 57, "ClientFavoriteCountry" : [ "AUS", "UK" ] }

Here is the query to call pretty() function −

> db.prettyDemo.find().pretty();

The following is the output −

{
   "_id" : ObjectId("5c8a440de01f572ca0ccf5f2"),
   "ClientName" : "Larry",
   "ClientAge" : 27,
   "ClientFavouriteCountry" : [
      "US",
      "UK"
   ]
}
{
   "_id" : ObjectId("5c8a4420e01f572ca0ccf5f3"),
   "ClientName" : "Mike",
   "ClientAge" : 57,
   "ClientFavoriteCountry" : [
      "AUS",
      "UK"
   ]
}
