Node.js MongoDB Limit is a useful feature that allows you to limit the number of documents returned in a query. This can be useful when you only need a certain number of documents and don't want to retrieve the entire collection. In this tutorial, we will go over how to use the limit function in a Node.js MongoDB query.
First, you will need to connect to your MongoDB database using the Mongoose library. Once connected, you can use the find() method to retrieve documents from a collection. To limit the number of documents returned, you can pass an object to the find() method with the limit property set to the number of documents you want to retrieve.
For example, to retrieve only the first 5 documents from the "users" collection, you can use the following code:
In this example, the find() method is used to retrieve all documents from the "users" collection, and the limit() method is used to limit the number of documents returned to 5. The exec() method is used to execute the query and return the results.
It is important to note that the limit() method affects the number of documents returned, not the number of documents retrieved from the database. If you want to retrieve a certain number of documents from the database, you should use the skip() method in conjunction with the limit() method.
In conclusion, Node.js MongoDB Limit is a useful feature that allows you to limit the number of documents returned in a query, and it is easy to implement using the Mongoose library. With the limit() method, you can easily retrieve the number of documents you need without having to retrieve the entire collection.
