Implementing Search and Filter Functionality Using useSearchParams in React

When developing engaging user interfaces, one common requirement is enabling users to search and filter through lists of data. In this guide, we're going to explore how to implement a practical search and filter function in your React application using the useSearchParams from React Router. If you've encountered issues with implementing this feature, worry not! We will break down the solution into clear, manageable sections.

Understanding the Problem

Imagine a situation where your application displays a list of profiles, each characterized by properties like PROFILE_NUMBER, NAME, AGE, and HOBBY. You want users to search for profiles via the PROFILE_NUMBER, and upon inputting a query, the list should dynamically update to show matching results.
However, you're experiencing a hurdle where the input field accepts text but does not filter the list as expected. You might see something like this in your code:

The problem here lies in the incorrect use of the filtering logic. Let's walk through the solution to make your search functionality robust.

Solution Breakdown

Step 1: Setting Up State with useSearchParams

The first step involves using the useSearchParams hook to manage the state of the input value. This allows you to capture user input and update the URL query parameters accordingly. Below is how you can implement this in your component:

With this, searchParams will hold your current URL parameters, and setSearchParams will be used to update them based on user input.

Step 2: Designing the Input Field

Next, create an input field that collects user input. You will want to handle changes in this input to update the search parameters accordingly.

Step 3: Filtering the Data

This is where you implement the core filtering logic for your profiles based on the user input. Here’s the correct way to filter through the profiles:

This component will render the full profile information accordingly.

Conclusion

By following these steps, you can successfully implement a search and filter function in your React application using useSearchParams. This not only enhances your app’s functionality but also significantly improves the overall user experience. Now that you are equipped with this knowledge, you can easily adapt this methodology to suit your needs.

Remember, the essential part is in correctly filtering the data based on user input!
