![]() ![]() The useParams hook is used to extract the dynamic part of a URL and returns the data as key/value pairs, while the useSearchParams hook allows you to access and modify the query parameters in a URL. With all being said, the useParams and useSearchParams hooks provided by the React Router library are essential tools for React developers to extract and manipulate data from a URL. You can build upon this example to create more complex URL-driven components in your projects! Conclusion This is just a simple example of how you can use the useSearchParams hook to modify query parameters and update the URL dynamically in any React application. The category state is initialized with the current value of the category query parameter, and the setCategory update function is used to modify the category state whenever the user selects a new filter category by clicking on a button.Īssuming the user clicks the button "electronics", The handeFilter function is called which then modifies the category query parameter using the set method of the useSearchParams object, and then updates the URL using the navigate function provided by the useNavigate hook that automatically updates the URL to localhost:3000/products?category=electronics. In this example, the useNavigate hook from the react-router-dom library is used to navigate us to a new route anytime a button is clicked, and the button receives an argument that determines the route we would navigate to. Let's say for example we have a react component that helps display a single item for a particular product on an e-commerce page. This is usually that part of a URL that helps you navigate to a particular route to display a single item such as displaying a specific user profile, a specific product, or a specific blog post. The useParams hook helps you extract the dynamic part attached to a URL and returns an object of key/value pairs of the dynamic parameter in a URL. ![]() This hook makes it easy to access the dynamic URL parameter and use them to display dynamic content based on that URL. This is a hook provided by the React Router library that allows you to extract data from a URL and use it within your React components. ![]() Instead, your app can immediately render some new UI and make data requests with a fetch to update the page with new information.Īlthough the useParams and useSearchParams hooks are relatively simple to eliminate in a small project, they are less commonly used compared to the more fundamental hooks such as useState, useEffect, useContext, and useReducer, which are crucial in any React project and cannot be dispensed with easily. NOTE: Client-side routing is what allows your React application to update its URL from a link click without making another request for another document from the server. The react-router-dom package enables client-side routing in our applications. You can use the useLocation hook to access the arch value to create a URLSearchParams object, then a useEffect hook to issue the side-effect based on any specific queryString parameter updating.Įxample: import from '.As a React developer, the react-router-dom is an essential package and a necessary dependency in any React project that requires navigation between routes. There's nothing in that directly does this, so you'd need to implement this yourself. ![]()
