Vue router reloading the current route - vuejs2

Question

Without reloading the whole page I need to reload the current route again (Only a component reload) in a vue app.
I am having a path in vue router like below,
{
path: "/dashboard",
name: "dashboard",
component: loadView("Dashboard"),
},
When user clicks on the Dashboard navigation item user will be redirected to the Dashboard page with vue router programmatic navigation
this.$router.push({ name: "dashboard" });
But when user already in the dashboard route and user clicks the Dashboard nav item again nothing happens. I think this is vue router's default behaviour. But I need to force reload the Dashboard component (Not to refresh the whole page).
I can't use beforeRouteUpdate since the router is not updated. Also I have tried the global before guards like beforeEach. But it is also not working.
How can I force reload the dashboard component without reloading the whole page?

Answer 1

It can be done in two ways.
1) Try doing vm.$forceUpdate(); as suggested here.
2) You can take the strategy of assigning keys to children, but whenever you want to re-render a component, you just update the key.
<template>
<component-to-re-render :key="componentKey" />
</template>
<script>
export default {
data() {
return {
componentKey: 0,
};
},
methods: {
forceRerender() {
this.componentKey += 1;
}
}
}
</script>
Every time that forceRerender is called, the prop componentKey will change. When this happens, Vue will know that it has to destroy the component and create a new one.
What you get is a child component that will re-initialize itself and “reset” its state.

Not mentioned here, but as the offered solutions require a lot of additional work just to get the app to render correctly, which imo is a brittle solution.. we have just implemented another solution which works quite well..
Although it is a total hack.
if (this.$route.name === redirect.name) {
// this is a filthy hack - the vue router will not reload the current page and then have vue update the view.
// This hack routes to a generic page, then after this has happened the real redirect can happen
// It happens on most devices too fast to be noticed by the human eye, and in addition does not do a window
// redirect which breaks the mobile apps.
await this.$router.push({
name: RouteNames.ROUTE_REDIRECT_PLACEHOLDER
});
}
... now continue to do your normal redirect.
Essentially, redirect to a placeholder, await the response but then immediately continue to another page you actually wanted to move toward
