Dynamic Routes in Next.js 14

    Understanding Dynamic Routes:

    Dynamic routes in Next.js allow developers to create pages with URLs that dynamically adapt to the content being served. This flexibility is achieved through the use of brackets ([ ]) in the route definition. For instance, a dynamic route like messages/[id] signifies that the page can be accessed with URLs such as messages/1, messages/2, etc., where 1, 2, etc., are dynamic parameters.

    Creating a Dynamic Server Component: To illustrate dynamic routing in action, let's build a simple Next.js 14 server component that displays messages based on the provided message ID.

    import React from "react";
    function Message({ params }: { params: { id: string } }) {
      return (
        <div className="flex flex-col gap-8 w-full max-w-xl">
          <div>Message: {params.id} </div>
    export default Message;

    In the above code snippet, we define a functional component Message that receives params as a prop containing the dynamic parameter id. Within the component, we render a simple message displaying the provided id. In an actual app we would likely fetch the message from a database or an API, based on the id parameter, but for the sake of simplicity we'll just display the id in the browser.
