How to Make the Best use of API Pagination with Node js

In case you’re not familiar with HAL, it stands for Hypertext Application Language. It also allows your API to be served and consumed using open source libraries available for most programming languages. These expectations don’t necessarily line up with the technical requirements of an API. In the era of big data and analytics, APIs are dealing with larger amounts of data in their backend than ever before. To truly stand their ground in today’s digital economy, APIs must be optimized for peak efficiency.

Express-Paginate works well with various data sources and is highly customizable. This general approach can be adapted to different backend frameworks and programming languages. Of course, the specific implementation details may vary depending on your technology stack and the data source you’re working with. However, it can become inefficient for large datasets since the offset must be calculated and skipped for each page, potentially impacting performance. Select an optimal page size that balances the amount of data returned per page. A smaller page size reduces the response payload and improves performance, while a larger page size reduces the number of requests required.

Best Practices for Web API Pagination

Connect and share knowledge within a single location that is structured and easy to search.

Offset pagination is the most straightforward method of pagination. It’s similar to skipping chapters in a book to reach a desired section.

It offers robust support for pagination out of the box, allowing you to paginate API responses using the PageNumberPagination or CursorPagination classes. Django Rest Framework handles the pagination logic and provides configurable options for controlling the pagination behavior. When it comes to implementing web API pagination, several tools and libraries are available that can simplify the process. In the above API request, the cursor value eyJpZCI6MX0 represents the identifier of the last fetched record. This request retrieves the next page of posts after that specific cursor.

There’s also the possibility of navigating to nonexistent pages (e.g. you use an offset value that’s larger than the data set size), which can lead to errors when retrieving data. Offset pagination has its limitations, however, such as the limitations of large offset values and inaccuracies that come from page drift. Keyset pagination is a bit more robust, but it’s also tightly tied to page results.

Instead of relying on numeric offsets, cursor-based pagination uses a unique identifier or token to mark the position in the dataset. The API consumer includes the cursor value in subsequent requests to fetch the next page of data. In conclusion, while implementing pagination alone can significantly enhance site navigation and user experience, it’s crucial to be attentive to user needs and preferences. Regularly collecting feedback and analyzing user behavior can help refine and optimize the pagination strategy for better user experience.

Implementing

Search engine bots may not be able to ‘tell’ that the pages with similar content actually represent different products. There is also a likelihood that the crawl budget will be spent on the pages that the pagination directs to, and other significant pages may never be crawled nor indexed. Where numbering is used, the user is able to decide how many more pages they are willing to look at. Once the user reaches the end of the page or has seen several items in a particular category,  it is intuitive that they will want to see more results. Crazy Coffee Crave example is what most websites use for their pagination.

After implementing pagination on your site, you need to prioritize the most important pages on your home page, or on the page where pagination begins. Search engines like Google are also a great example of using pagination in search engine results. This makes it easier for users to find what they are looking for in other pages if they cannot find it on page 1. This helps search engines understand the relationship between paginated pages. You’ll be directing search engines to treat the paginated pages as part of the ‘View all’ page. Combined pagination is a hybrid approach that integrates various pagination methods to optimize data retrieval and navigation in APIs.

Make Paginated Pages Canonical

Cursors are used for dynamic datasets, while keyset pagination is efficient for large datasets with stable sorting. Beyond just segmenting data, pagination also enhances the user experience and ensures that your API is efficient. Without pagination, users might face long loading times or even timeouts when retrieving large amounts of data. It also conserves server resources, preventing overloading and potential system failures.

We’ve learned a lot about how API pagination works and why it’s important. Let’s conclude with a real-world example to help you work pagination into your own API design. To implement this feature, we call the updateActiveButtonStates() function whenever a page is changed or displayed.

Use Parameter URLs for the Paginated Pages

If a user is interested in more details about the product, they can click on the image/price/link with a call to action to learn more. Pagination also makes it easier for a user to find the information they are looking for. Since SlideShare is a big aggregated site, the best way to help users go through their site is to provide pagination alphabetically or if it contains numbers.

  • Now if there’s a need to get a snapshot of the data, I would just provide an API call that provides all the data in one request with no pagination.
  • If you’re using GraphQL for your web API, pagination libraries are available that provide pagination capabilities for GraphQL queries.
  • Adopt a consistent naming convention for pagination parameters, such as “offset” and “limit” or “page” and “size.” This makes it easier for API consumers to understand and use your pagination system.
  • The cursor can be based on various criteria, such as a timestamp, a primary key, or an encoded representation of the record.
  • Django Rest Framework handles the pagination logic and provides configurable options for controlling the pagination behavior.

The API response includes a limited set of data starting from the cursor position. Offset-based pagination involves specifying the page number and the number of items per page. The API response includes a subset of the data starting from a specific offset. For example, you might request page 2 with 10 items per page, which would return items 11 to 20.

Cursor-Based Pagination

A good implementation of this method you can see on the wikimart.ru on the final branches of the directory. Developer.com features tutorials, news, and how-tos focused on topics relevant to software engineers, web developers, programmers, and product managers of development teams. This includes coverage of software management systems and project management (PM) software – all aimed at helping to shorten the software development lifecycle (SDL). However, excessively large page sizes may make it challenging for users to find specific records or navigate through the data efficiently.
