Best way to preload route data before accessing the route.

Before rendering the page for a given route, I want to first get the necessary data synchronously. Ideally I'd like to get the data in the page component, but I'm not opposed to doing it in the router file. I've read and tried various approaches, but part of the challenge comes from the fact that there are multiple ways to build components, and the use of certain features varies.

What are the performance numbers next to components in the Vue dev tools?

Does anyone have insights or resources for a certain feature in the Vue development tools? On the components pane, it shows my component, and then these little red and yellow squares, and what I'm assuming is the performance of the component. When I first load the app they don't appear, but for example I updated a text input component that validates its own formatting when the user enters a new value. This updates the Vuex storage and/or computed properties, but what baffles me is why the whole thing lights up like an angry Christmas tree. These performance data are displayed for unrelated components. When I check the Vuex history
