Async fetch data once on app startup

[matthewthomsonnz]

Hi there,

I need to fetch data only once when I first run the app. Like if I were to use getStaticProps in the _app.js file.

I don't want to use getInitialProps because it forces SSR site wide and I will be building to static files.

Is there seriously no built in way to do this? I've exhausted every google search
