Using Route Parameters to Pass Data Between Routes in Vue Router

In Vue Router, route parameters are a powerful feature that allows you to pass data between routes. This approach enables you to share data between different components and views in your application. In this article, we will explore how to use route parameters to pass data between routes in Vue Router.

What are Route Parameters?

Route parameters are values that are passed as part of the URL. They are defined in the route configuration using a colon (:) followed by the parameter name. For example:

const routes = [
  {
    path: '/users/:id',
    name: 'user',
    component: UserComponent
  }
]

In this example, the `:id` is a route parameter that will be passed as part of the URL. When the user navigates to the `/users/123` route, the `id` parameter will be available in the component.

How to Access Route Parameters in a Component

To access route parameters in a component, you can use the `$route` object. The `$route` object is an instance of the `Route` class and provides information about the current route.

Here is an example of how to access the `id` parameter in a component:

export default {
  name: 'UserComponent',
  mounted() {
    console.log(this.$route.params.id)
  }
}

In this example, the `mounted` lifecycle hook is used to access the `id` parameter. The `params` property of the `$route` object contains an object with the route parameters.

How to Pass Data Between Routes Using Route Parameters

To pass data between routes using route parameters, you can define a route parameter in the route configuration and then access it in the component.

Here is an example of how to pass data between routes using route parameters:

const routes = [
  {
    path: '/users/:id',
    name: 'user',
    component: UserComponent
  },
  {
    path: '/users/:id/profile',
    name: 'user-profile',
    component: UserProfileComponent
  }
]

In this example, the `:id` parameter is defined in both routes. When the user navigates from the `/users/123` route to the `/users/123/profile` route, the `id` parameter will be passed to the `UserProfileComponent`.

Here is an example of how to access the `id` parameter in the `UserProfileComponent`:

export default {
  name: 'UserProfileComponent',
  mounted() {
    console.log(this.$route.params.id)
  }
}

Using Route Parameters with Named Routes

Route parameters can also be used with named routes. Named routes are routes that have a name property defined in the route configuration.

Here is an example of how to use route parameters with named routes:

const routes = [
  {
    path: '/users/:id',
    name: 'user',
    component: UserComponent
  }
]

To navigate to a named route with route parameters, you can use the `$router.push` method:

this.$router.push({ name: 'user', params: { id: 123 } })

In this example, the `name` property is set to `'user'` and the `params` property is set to an object with the `id` parameter.

Conclusion

In this article, we explored how to use route parameters to pass data between routes in Vue Router. Route parameters are a powerful feature that allows you to share data between different components and views in your application. By defining route parameters in the route configuration and accessing them in the component, you can pass data between routes and create a more dynamic and interactive user experience.
