Introduction to Pagination in Vue.js Framework

Pagination is an essential feature in web applications, allowing users to browse through large datasets without overwhelming them with too much information at once. If you find yourself dealing with pagination issues in Vue.js, you are not alone.

One common issue developers face is displaying too many records on the same page, which can negatively impact user experience. In this guide, we'll address a specific problem: How to effectively paginate a list of posts in Vue.js when working with Bootstrap 4.

Problem Statement

You have a Vue.js application that successfully implements a pagination bar, but currently, all 50 records are being displayed on a single page instead of only the specified number of records per page. In this case, the pagination is functioning, but the actual records go beyond what is intended for display.

Solution Overview

The solution to the pagination problem can be tackled by using computed properties in Vue.js. This allows you to slice the array of posts into smaller, manageable chunks based on the current page and the number of posts you want to display per page.

Let's break down the solution into several organized sections for clarity.

Step 1: Slice Your Posts Array

To implement pagination, you need to create a computed property that will handle the logic of slicing the posts array. Here's how to do this in your Vue.js component:

In the code above:

this.perPage * (this.currentPage - 1) determines the starting index for slicing the posts.

this.perPage * (this.currentPage - 1) + this.perPage sets the ending index for the slice, allowing you to get the correct number of posts for the current page.

Step 2: Update the Template to Bind the Sliced Array

Once you’ve created your computed property, the next step is to bind it in your template. This requires you to modify the v-for directive in your PostList component to use the new paginatedposts computed property instead of the original posts array:

With this change, the PostList component will now only receive and display the posts relevant to the current page.

Step 3: Testing the Solution

After implementing the changes, it's essential to test the pagination feature. Here are some steps to ensure everything is working correctly:

Navigate through the pagination buttons and observe that the records change according to the specified perPage count.

Verify that no records exceed the defined number per page.

Conclusion

Implementing pagination in your Vue.js application does not have to be complex. By using computed properties effectively, you can manage how much data is presented to your users and enhance their overall experience on your site.

Now that you've learned how to set up pagination in Vue.js, you can ensure your application is efficient and user-friendly. Happy coding!
