Make a directory for dbPath with the following command: sudo mkdir -p /data/db Finally, start the MongoDB server by running mongod from the command line. By default, this is /data/db, but you can specify a different location if you prefer. Once you have MongoDB installed, create a data directory where MongoDB will store its data files.

They're especially good at handling unstructured data, so they can be a good choice if you're dealing with a lot of data that doesn't fit into a traditional relational database. No-SQL databases are powerful tools that can help you work with large amounts of data. It's fast, scalable, and uses JSON documents to store data. MongoDB is one of the most popular NoSQL databases. NoSQL databases are often used for big data and real-time web applications. PrerequisitesĪ NoSQL database is a non-relational database that does not use the traditional table-based schema of a relational database. This article covers the basics that you need to know to get started with MongoDB and how to use it properly. It offers high scalability, reliability, and performance even with a huge amount of data. And it has many advantages over traditional SQL databases. Moreover, by implementing pagination links, we can provide a better user experience and improve the performance of our application.MongoDB is an increasingly popular open source NoSQL database. By using the limit() and skip() methods, we can retrieve a subset of the data on each request and optimize the data retrieval process. Server-side pagination is an effective technique to handle large datasets in MongoDB. In the example above, we generate an array of pagination links, where each link has a pageNumber property and an isActive property that indicates whether the link is for the current page. const pageNumber = 1 Ĭonst users = await db.collection('users'). The limit() method limits the number of documents to retrieve, and the skip() method skips a certain number of documents before starting to retrieve them. ![]() To retrieve data for a specific page, we need to use the limit() and skip() methods. const pageSize = 10 Ĭonst totalCount = await db.collection('users').count() Ĭonst totalPages = Math.ceil(totalCount / pageSize) How to retrieve data for a specific page ![]() We can use the count() method to count the total number of documents in the collection. To calculate the number of pages, we must divide the total number of documents by page size. Typically, the page size ranges from 10 to 100 documents per page. We can set the page size to any value that makes sense for our application. The first step is to define the page size, which determines how many documents we want to retrieve on each request. Here is a step-by-step guide to implementing server-side pagination in MongoDB: How can we define the page size? To implement server-side pagination in MongoDB, we can use the limit() and skip() methods, which allow us to specify how many documents we want to retrieve and how many documents we want to skip, respectively. In this way, the server can optimize the data retrieval process, and the client can display the data more efficiently. Instead of retrieving all data at once, the server sends a subset of the data to the client on each request. Server-side pagination is a technique that splits large datasets into smaller chunks to make them more manageable. In this article, we will discuss how to do server-side pagination in MongoDB. When working with large datasets, it is essential to implement pagination to improve performance and reduce the amount of data transferred over the network. MongoDB is a popular document-oriented NoSQL database that stores data in JSON-like documents with dynamic schema.
