    ## Vite Routing with Parameters.

    Vite provides an intuitive and flexible API for defining routes and handling parameters. By utilizing the `createRouter` function, developers can establish a set of routes with corresponding components and utilize dynamic segments to capture user-specific data. This enables the creation of intuitive and responsive front-end applications with a strong focus on user experience.
    ### Defining Routes with Parameters.
    In Vite, defining routes with parameters is straightforward. Developers can utilize the `path` property to specify the route pattern, including any necessary parameters. Here's an example:
    javascript.
    const router = createRouter([。
      {。
        path: '/users/:id',。
        component: UserDetails,。
      },。
    ]);
    In this example, the `:id` segment in the `path` represents a dynamic parameter. When the user navigates to a URL like `/users/123`, the `id` parameter will be set to `123`.
    ### Accessing Parameters in Components.
    Within components, developers can access route parameters through the `$route` property. This property provides an object containing all the parameters defined in the route.
To access the `id` parameter from the previous example, the component can use the following code:
    javascript.
    export default {。
      setup() {。
        const id = $route.params.id;
        // ...
      },。
    };
    ### Using Parameters for Data Fetching.
    Route parameters can be leveraged to dynamically fetch data from an API or database.
By incorporating the `id` parameter into the request URL, developers can retrieve user-specific data and display it in the appropriate component.
    For instance, consider an API endpoint that returns user information based on their ID. The component can make a request to the following URL:
    javascript.
    const url = `/api/users/${$route.params.id}`;
    By dynamically building the request URL based on the `id` parameter, the component can retrieve the user's details and populate the corresponding UI elements.
    ### Conclusion.
    Vite's routing API empowers developers to effortlessly define routes with parameters, access those parameters within components, and utilize them for data fetching. This enables the creation of versatile and user-centric applications that adapt to dynamic scenar
ios. By leveraging the power of Vite's routing system, developers can elevate the user experience and create applications that are both functional and intuitive.
