I want to set the page title to a different value for each page.

In regular Vue.js, I have done the following:

```
import router from './router'
import { store } from './store/store';

router.beforeEach((to, from, next) => {
    store.mutations.setRoute(to);
    document.title = store.getters.pageTitle;
    next();
}

```

How would I get that effect in nuxt?

That is, on both initial page load and when changing pages, I want the browser tab's title to change. For instance, from "My App - About" to "My App - Profile".
