Refresh the page when the parameter in the URL changes

Question

Refresh the page when the parameter in the URL changes

I'm encountering a small issue that I can't seem to resolve.

Currently, I am on the following page:

http://example.com:8080/#/user/5ad142e8063ebb0537c5343e

There is a link on this page that points to the URL below:

http://example.com:8080/#/user/5ac00b02bb055f37b3fd2d07

However, when I click on the link, the URL changes but the content remains the same. The content does not reload unless I manually refresh the page.

The code for the link is as follows:

<router-link  :to="{ name: 'User', params: { id: user.id }}">
        <span class="glyphicon glyphicon-cog"></span> Profil
</router-link>

Is there a way to force the page to reload automatically?

The reason behind this behavior is related to dynamic route matching. The component needs to be able to respond to changes in the url parameters:

It's important to understand that when navigating from /user/foo to /user/bar using routes with params, the same component instance will be reused. This approach is more efficient as it avoids destroying the old instance and creating a new one. However, keep in mind that the lifecycle hooks of the component will not be triggered.

There are two techniques to handle this situation: monitoring the $route object or employing the beforeRouteUpdate guard:

const User = {
     template: '...',
     watch: {
         '$route' (to, from) {
              // react to route changes...
          }
     }
}

Using the beforeRouteUpdate guard:

const User = {
    template: '...',
    beforeRouteUpdate (to, from, next) { 
        // react to route changes... 
        // don't forget to call next() 
    } 
}
