Vue-router component reusing - vue.js

Question

I would like to know how can I stop component reusing in Vue-router.
I'm building a simple page application and I am unable to update data after clicking the same link twice.
Is it possible to somehow force reloading or what are the best practices in my situation?

Answer 1

Use the key attribute on router-view set to current url. It's built in, so no need to write any code.
<router-view :key="$route.fullPath"></router-view>

Answer 2

Vue Router reuses the same component therefore the mounted hook won't be called. As stated in the documentation:
The same component instance will be reused [...] the lifecycle hooks of the component will not be called.
If you want to update the data you have two options:
Watch the $route object
const User = {
template: '...',
watch: {
'$route' (to, from) {
// react to route changes...
}
}
}
Use the beforeRouteUpdate navigation guard
const User = {
template: '...',
beforeRouteUpdate (to, from, next) {
// react to route changes...
// don't forget to call next()
}
}
For a more detailed explanation you can check the section Reacting to Param Changes of the Vue Router documentation: https://router.vuejs.org/guide/essentials/dynamic-matching.html#reacting-to-params-changes.

One way to do this is to put a key on the router-view and append a timestamp querystring to your router-link
const Home = {
template: '<div>Home</div>',
created() {
console.log('This should log everytime you click home.');
},
};
const router = new VueRouter({
mode: 'history',
routes: [
{ path: '/', component: Home },
]
});
new Vue({
router,
el: '#app',
});
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<div id="app">
<router-link :to="`/?q=${Date.now()}`">/home</router-link>
<router-view :key="$route.fullPath"></router-view>
</div>
One reason not to do it this way is because it'll force rerenders on components that you may want to be reused such as on routes like
