Querying Parameters from URL

Understanding Query Parameters

Before diving into implementation, let’s understand what query parameters are. Query parameters are key-value pairs appended to the end of a URL, separated by a question mark (?) and ampersands (&). For example, in the URL https://example.com/products?id=123&category=electronics, id and category are query parameters....

Steps to Create a NextJS application

Querying Parameters from URL

Querying parameters from the URL involves extracting key-value pairs from the URL string to access specific data or parameters associated with a web page or application, aiding in dynamic content generation and customization....

Using useRouter

In Next.js, you can use the useRouter hook from the next/router package to access query parameters from the URL. Simply import the useRouter hook in your component and call it to get the router object. Then, you can access the query object from the router object to retrieve query parameters passed in the URL....

Using useSearchParams

In Next.js, you can use the useSearchParams hook from the next/navigation package to access query parameters from the URL within functional components. By utilizing the .get method provided by useSearchParams, you can retrieve the value of specific query parameters. Ensure that the parameter names used with .get match those in the URL query string for accurate retrieval....

Using getInitialProps

In Next.js, the getInitialProps method is utilized within page components to fetch data and pass it as props before rendering, essential for server-side rendering and pre-rendering pages. It enables data fetching from APIs, server-side rendering, SEO enhancement, and dynamic content generation by handling query parameters efficiently....

Using getServerSideProps

getServerSideProps in Next.js serves a similar purpose to getInitialProps, allowing data fetching before page rendering. It dynamically fetches data on each request, enhancing server-side rendering, SEO, and performance. With its ability to handle query parameters effectively, it enables dynamic content generation and personalized user experiences....

Conclusion

In a Next.js application, the combination of the useRouter hook from the ‘next/router’ package and the useSearchParams hook from the ‘next/navigation’ package provides a powerful solution for accessing and processing query parameters from the URL within functional components. These hooks allow us to seamlessly integrate URL parameters in our application logic, enabling dynamic workflows. By utilizing the useRouter hook, developers gain access to the router object, which contains information about the current URL and its query parameters. On the other hand, the useSearchParams hook simplifies the process of extracting and managing query parameters directly from the URL’s search string....
