Vue-Router: How to use dynamic route matching to implement advanced routing?

Vue is a popular JavaScript framework that provides many useful plugins to create powerful web applications. One of them is Vue-Router, which is the official routing plugin for Vue.js that allows you to easily organize the structure of your application.

In Vue-Router, dynamic route matching is a very useful feature that allows us to create routes dynamically. By using dynamic routing, we can easily implement advanced routing, such as passing parameters in the URL of the application or dynamically generating routes.

In this article, we will introduce Vue-Router’s dynamic route matching feature and provide code examples to help you understand how it works.

Dynamic route matching

Dynamic route matching is a technology that allows us to define variable parts of the routing path. For dynamic routing, we can use wildcards to match anything.

In Vue-Router, we can define the dynamic part by adding a colon (:) in the routing path. For example, if we want to create a dynamic route whose path is "/books/:id", where ":id" represents a variable parameter. When we access "/books/100", "100" will be passed to the component as a parameter.

The following is a sample code using dynamic routing:

const router = new VueRouter({
    routes: [
        {
            path: '/books/:id',
            component: BookComponent
        }
    ]
})

In the above code, we create a dynamic route with the path "/books/:id" and add the BookComponent as a component.

Now, let's look at a more complex example using multiple dynamic parameters.

const router = new VueRouter({
    routes: [
        {
            path: '/books/:id/chapters/:chapterId',
            component: ChapterComponent
        }
    ]
})

In the above code, we create a dynamic route with the path "/books/:id/chapters/:chapterId" and use ChapterComponent as the component. When accessing "/books/100/chapters/1", "100" and "1" will be passed as parameters to ChapterComponent.

With dynamic route matching, we can easily implement advanced routing, such as:

• Routes with optional parameters
• Named routes with parameters
• Nested routing

Implement routing of optional parameters

In Vue-Router, you can use question marks (?) to define optional parameters. For example, if we want to create a route with optional parameters, the path is "/books/:id/?:chapterId", where "?:chapterId" represents an optional parameter.

The following is a sample code using optional parameters:

const router = new VueRouter({
    routes: [
        {
            path: '/books/:id/?:chapterId',
            component: ChapterComponent
        }
    ]
})

In the above code, we create a route with optional parameters whose path is "/books/:id/ ?:chapterId" and ChapterComponent as the component. When we access "/books/100", ChapterComponent will only display books and not chapters.

Implementing named routes with parameters

Named routes are very useful in Vue-Router. You can link to a specific route by using a name instead of a path. In dynamic routing, you can use named routes to pass multiple parameters.

The following is a sample code for a named route:

const router = new VueRouter({
    routes: [
        {
            path: '/books/:id/chapters/:chapterId',
            name: 'chapter',
            component: ChapterComponent
        }
    ]
})

In the above code, we create a named route with the name "chapter" and the path "/books/:id /chapters/:chapterId" and ChapterComponent as the component.

Using named routing, we can pass multiple parameters to the route by calling $router.push and link to the specified component:

router.push({
    name: 'chapter',
    params: {id: 100, chapterId: 1}
})

In the above code, we use the name The "chapter" parameter is passed to the route and "id" is set to 100 and "chapterId" is set to 1.

Implementing nested routing

Nested routing is a technology that allows us to create nested routes in Vue-Router. With nested routing, we can easily organize the structure of our application and divide it into smaller components.

The following is a sample code for a nested route:

const router = new VueRouter({
    routes: [
        {
            path: '/books/:id',
            component: BookComponent,
            children: [
                {
                    path: 'chapters/:chapterId',
                    component: ChapterComponent
                }
            ]
        }
    ]
})

In the above code, we create a nested route whose parent route is "/books/:id", and Make BookComponent the parent component. In the parent route, we also define a child route with the path "chapters/:chapterId" and ChapterComponent as a child component.

This way we can easily create more complex routing systems and split the application into multiple small components.

Summary

Dynamic route matching is a very useful feature in Vue-Router, allowing us to easily create dynamic routing and advanced routing. By using dynamic route matching, we can implement routes with optional parameters, named routes with parameters, and nested routes.

In this article, we provide specific code examples to implement these functions. I hope this article will be helpful to you and allow you to better understand the dynamic route matching function of Vue-Router.
