So this screen in @onlineornot.com has always been slower than I wanted - around 2.3s(!) to load 10 rows of data from the GraphQL endpoint.

It was the first screen I ever built (4+ yrs ago), and I leaned heavily into GraphQL resolvers because I assumed it'd be fast.

realised i was missing a pretty important empty state in @onlineornot.com today: when you search for something and there are no results

Took a little side-quest to improve pagination on OnlineOrNot's oldest screen (almost 4 years old)

It used cursor-based pagination, polling was super buggy with apollo-client. Now uses plain old numbered page pagination, feels snappier too.

Will implement it across the app.
