How to Implement Pagination in Express JS

This means that it is possible to create an infinite number of crawlable and indexable URLs, which would result in a massive duplicate content issue. You need to reduce the number of links from the pagination landing page to the specific paginated pages. This article by Google explains how to go about making a page canonical among other pages with duplicate content. This approach causes problems as it may result in paginated pages which are deeper in the link structure not being indexed at all. After getting data on how your site currently implements pagination, you are now ready to fix the identified issues.

These filters create new and unique URLs based on the parameters used to filter. This major search engine is able to identify related pages, even when directives like noindex and the canonical tag are not used. Search engine bots may not be able to ‘tell’ that the pages with similar content actually represent different products. In worst cases, they may flag your site for duplicate content. If you split content types as a single article spread across multiple pages, you may end up with pages with little content. They want content that is valuable to the user, and answers a user’s intent.

Are there situations where infinite scroll is more beneficial than traditional pagination on mobile interfaces?

Load more and infinite scroll are generally implemented using the Ajax load method ( JavaScript ). Since the implementation is rather complicated, you should be very careful when applying this method. The “View All” page should load rather quickly, preferably within 1-3 seconds. For this solution, you’ll be adding a meta tag to the section of paginated pages. Due to the inheritance of the paging parameters through the QueryStringParameters class, we get the same behavior.

Now, these classes look a bit empty, but soon we’ll be populating them with other useful parameters and we’ll see what the real benefit is. For now, it’s important that we have a way to send a  different set of parameters for AccountController and OwnerController. We will also write a custom React hook that gives us a range of numbers to be rendered by the pagination component.

Remember that the choice of pagination strategy will largely depend on the specific requirements of your application and the nature of the data you’re dealing with. In web development, pagination is a crucial feature for handling the display of large datasets. It allows developers to present data in a more organized and user-friendly manner, loading a limited number of items per page. This tutorial will walk you through the process of implementing pagination in a web application using Express.js, a common backend framework for Node.js applications. We’ll start with a basic example and progressively move to more advanced techniques, covering different pagination strategies and best practices.

Small data sets do work on effectively on offset pagination but large realtime datasets do require cursor pagination. We also want to define what is pagination a function to add the active class to the page number we just clicked. We reset all buttons on the page by removing the active class.

Add Page Number Buttons Event Listener

Therefore, it is better to block pages from indexing with the help of the robots meta tag . Website pagination makes it easier for users to find the information they are looking for. Users immediately understand the site structure and can get to the desired page in a single click. One of the indirect signs of content quality is the time users spend on the site. The more convenient it is for users to move between paginated content, the more time they spend on your site. Numbering is displayed at the top or bottom of the page and allows users to move from one group of links to another.

If the index is within the range, the toggle keyword applies the hidden class (which we’ll define in our CSS code) to the item, effectively hiding it. If the index doesn’t meet either condition, the hidden class is removed, making the item visible. In general, we’ve found that cursor-based pagination is the most powerful of those designed. As a reminder that the cursors are opaque and that their format should not be relied upon, we suggest base64 encoding them. There are several ways to help search engines understand that your paginated content is not duplicated and to get it to rank well on SERPs. Splitting information across several pages increases the website’s usability .

Can I Use Pagination with a Database?

In this case, duplicate content on website can cause difficulties for search engines when it’s time to determine the most relevant pages for a particular search query. The canonical tag will make it easier for the search engine bots to realize that all the other pages with pagination are a part of the view-all page. Pagination is the numbering of site pages in ascending order. Website pagination comes in handy when you want to split content across pages and show an extensive data set in manageable chunks. In conclusion, pagination is an essential element of web development for creating scalable and user-friendly applications.

  • Connect and share knowledge within a single location that is structured and easy to search.
  • Line 2 – Read the Query string on the request for page filter properties.
  • We have already mentioned a few reasons that necessitate the use of pagination, for example, when there is a large amount of data that can’t reasonably be presented as a single page.
  • If an accurate live scrolling view is needed, REST APIs which are request/response in nature are not well suited for this purpose.
  • This is the core function of the entire implementation, the actual paging.

To handle the mentioned drawbacks of the normal keyset pagination, you can add an offset to the timestamp and use a so-called “Continuation Token” or “Cursor”. The offset is the position of the element relative to the first element with the same timestamp. It’s passed to the client in the response and can be submitted back to the server in order to retrieve the next page. Using ‘old’ pagination techniques is entirely unavoidable as the ‘old’ approaches are still important, especially when it comes to internal linking. Internal linking will make it easier for search engine bots to find paginated pages. When your site has large amounts of data, search engine bots need to use their crawl budget wisely.

This doesn’t, however, mean that they are not using pagination on their site. The for loop ranges from 0 (which is the first page) to the total number of pages minus 1. You can view our full HTML code, along with some styling, on CodePen.

HasPrevious is true if CurrentPage is larger than 1, and HasNext is calculated if CurrentPage is smaller than the number of total pages. TotalPages is calculated by dividing the number of items by the page size and then rounding it to the larger number since a page needs to exist even if there is one item on it. PagedList will inherit from the List class and will add some more to it. We can also, move the skip/take logic to the PagedList since it makes more sense. Since we’re returning just a subset of results to the caller, we might as well have a PagedList instead of List.

It prevents the creation of new URLs based on the filters that a user chooses. You could also determine the parameters without any SEO value and prevent them from being crawled and indexed. There are sites that allow filters in order to show more relevant options to the user.
