Understanding params in next.js for dynamic routing and data fetching | Next.js tutorial in hindi

Описание: In Next.js, "params" refers to the parameters used for dynamic routing. Dynamic routing allows a portion of the URL path to change based on certain parameters. These parameters are defined using brackets `[]` in the page or API route filenames.

When a request is made to a dynamic route, Next.js matches the route and provides the parameter values in the `params` object. You can access this object in functions like `getStaticProps`, `getStaticPaths`, `getServerSideProps`, or `getInitialProps` depending on the Next.js version.

By using the `params` object, you can fetch data based on the parameter values and pass them as props to your components. For example, you can fetch specific blog post data based on the `slug` parameter in a `getStaticProps` function. The `getStaticPaths` function is used to define the possible values for the parameter.

Overall, the `params` object allows you to create dynamic routes and handle data fetching based on the parameter values in Next.js.
