How to Get the Current Page Number in React Slick

If you are working with the React Slick carousel library, you may find yourself facing an interesting challenge: how to determine the current page number when utilizing multiple slides. This is particularly important if you want to display navigation arrows that show the format currentPage / TotalPages, such as 1 / 4. Imagine the frustration when you see the output being incorrect, like getting 5 / 2 instead. In this post, we will break down the problem and walk through an effective solution that you can implement in your own projects.

Understanding the Problem

When using React Slick, you might have noticed that while the library provides easy ways to access the total number of slides, tracking the current slide (or page) might not be straightforward. This task becomes even trickier when you're working with responsive designs where slide visibility changes based on screen size.

To resolve this, you need a comprehensive method that allows you to respond to page changes both when navigating forward or backward through the slides.

The Solution

The good news is that you can achieve this with a few modifications to your existing code. Let’s break it down into manageable steps.

Step 1: Set Up State Management

First, you need to manage the state for the current page. This can be set up using the useState hook from React.

Step 2: Handle Slide Transitions

Next, you need to handle the transitions between slides. We can create functions that will adjust the current page when the user clicks on the navigation arrows to move forward or backward.

Step 3: Update Pagination on Change

Utilizing React Slick's afterChange and customPaging callbacks, you can update your states to display the correct numbers. Here's an example of how you can do this:

Step 4: Displaying the Current Page

With the above setup, you should now be able to show your current page and total page number conveniently. Simply render this information in your component, like so:

Common Issues

While this implementation should solve the immediate issue, you may encounter a few challenges, such as the scrolling behavior not working as expected. For instance, you might find that navigating backwards behaves differently than moving forwards.

Additional Considerations

Should you find that React Slick is not meeting your needs for performance or ease of use, consider looking into alternative carousel libraries. Some popular options include:

Swiper.js - Highly customizable and includes various features.

Owl Carousel - Another solid choice with good performance.

Tiny Slider - A lightweight slider with responsive settings for ease of use.

Conclusion

Tracking the current page number in React Slick may initially seem challenging, but with a proper state management approach and a few callback functions, you can effectively display it in your navigation. Implement the steps outlined above to improve your users’ experience with clear navigation indicators.
