Pretty printing in MongoDB
This article will discuss how to use pretty printing in MongoDB to display formatted results.
Pretty printing in MongoDB
A cursor is an object that allows programmers in the Mongo world to iterate over documents in a Mongo collection. Although developers can explicitly iterate over the items returned in a cursor object, the functionality of cursors allows for automatic iteration over query results.
The pretty() method in Mongo Universe defines a cursor object to display Mongo query results in a readable and attractive layout. This strategy is very useful if our database is large.
grammar:
> db.collectionName.find(queryString).pretty()
queryString is a selection input parameter that can be used to fetch documents from the collection based on the given selection criteria.
Use cursor.pretty()the method to make a JSON document or collection more attractive in the Mongo Shell. The Mongo Shell does not always like this approach.
You can find more information about .pretty() in the documentation of .pretty() . Let’s understand the ideas mentioned above with the following example.
Code:
> db.users.find()
> db.users.find().pretty()
In the previous example, we are targeting all users, regardless of the method. The main difference between the two queries is that the latter returns data in a more readable way, while the former provides data in a denser format.
Run the above code in MongoShell which is compatible with MongoDB. It will display the following result.
Output:
{ "_id" : ObjectId("54f612b6029b47909a90cesd"), "email" : "johndoe@example.com", "comment" : "This is the first user in the collection.", "country" : "United Kingdom" }
{
"_id" : ObjectId("54f612b6029b47909a90cesd"),
"email" : "johndoe@example.com",
"comment" : "This is the first user in the collection.",
"country" : "United Kingdom"
}
