Custom Navigation Buttons in Swiper for React: A Complete Fix

When working with the Swiper library in React, developers often run into issues while trying to create custom navigation buttons for sliding functionality. In this guide, we will address a common problem: how to make custom next and previous buttons work with the Swiper component in React.

Understanding the Problem

In the given code example, the developer attempted to use React's useRef hook to create references for the navigation buttons. However, it was noticed that the buttons did not respond as expected, even though everything else in the swiper component functioned properly.

Key Observations:

The nextRef.current and prevRef.current were undefined at the time of the Swiper initialization.

Despite properly rendering the steps in the slider, the custom buttons were non-functional.

Solution Breakdown

1. Using Class Names for Navigation

One easy solution is to leverage class names to define navigation elements, rather than using React refs directly. The Swiper component can accept selectors as strings for the nextEl and prevEl properties. Here’s a simplified adjusted code snippet:

2. Reinitializing Swiper with useRef

If you want to retain the use of useRef, a more dynamic approach would be to re-initialize your Swiper component after the first render. Here’s how you can achieve that by including a state variable:

Explanation of the Approach:

swiperKey: This key triggers a re-render of the Swiper component when updated, ensuring that refs are properly initialized after the first render.

useEffect(): It's used here to modify the swiperKey, causing the component to reinitialize and allowing nextRef and prevRef to have defined values during swiper initialization.

Conclusion

By following these suggestions, you can successfully implement custom navigation buttons in your Swiper component within a React application. The first solution, using class names, is typically the quickest fix, while the second option provides a way to keep using React's ref system.

Navigating through the challenges in developing with Swiper can be daunting, but with clear strategies like the above, you can enhance your user interface effectively.
