Refresh the Vue component in a single-page application project

As I develop a spa app using vue js, I have set up these routes:

{ path: '/artikel/create',name: 'artikelCreate', components: { default: artikel_form, 'header': header} },
{ path: '/artikel/edit/:id',name: 'artikelEdit', components: { default: artikel_form, 'header': header}, meta: { mode:'edit' } },

The artikelCreate route creates a blank form from the artikel_form component, while the artikelEdit route populates the form with data based on the :id. Both use the same artikel_form component.

This setup allows me to avoid creating two very similar form components. By checking this.$route.meta.mode === 'edit', I can determine whether the route is for editing or creating an article and perform relevant actions.

However, I encountered an issue when following these steps:

Navigating to the artikelEdit route displays the populated artikel_form component.
Despite having a navigation bar, moving from the artikelEdit route to the artikelCreate route does not result in a new empty form being created as expected.
Even after changing routes, the artikel_form component remains from the artikelEdit route instead of resetting for the artikelCreate route.

Is there a more elegant way to reset or recreate components in vue, rather than just cleaning out input bindings like v-model? This method may become cumbersome for components with complex dependencies beyond basic text inputs in a form, and it also leaves room for errors if each input must be specified individually.

Any suggestions on how to reload, refresh, or entirely recreate a component in vue?

Vue does not reload the component because it considers it to be the same component with the same object reference, even when the route changes.

To solve this issue, we need to clone the artikel_form so that each instance has a different reference. We can achieve this by using the object spread operator

{
    path: '/artikel/create',
    name: 'artikelCreate',
    components: {
        default: {...artikel_form},
        'header': header
    }
},
{
    path: '/artikel/edit/:id',
    name: 'artikelEdit',
    components: {
        default: {...artikel_form},
        'header': header
    },
    meta: {
        mode:'edit'
    }
},
