Build a Reactive Backend for a Web App
Convex is a JS-powered database and backend for web apps that’s reactive — you can use it to create endpoints and queries that update automatically when data changes. Tom Ballinger will teach us how.

Data Interactivity in the Serverless Future (HYTRADBOI 2022)
Dynamic application developers need global state management, not a database. James (@jamesacowling) presents his talk from the HYTRADBOI 2022 database conference on how Convex is rethinking how app developers manage global state.

The unfulfilled promise of functional ideals on the web
Ideas around immutability, purity, and dataflow programming are quietly saturating our technologies like Bitcoin and React. And while these early inroads are enabling exciting new ways to build large and dependable applications, there is still much to do to realize the full potential of this revolution.

Fully Reactive Pagination
Paginating over large datasets is tricky when the data is changing. Naive approaches result in missing or duplicated data. The trick is to rewrite limit queries (fetch 5 items) into range queries (fetch between cursors). Convex handles this automatically!

Managing Reactivity with useBufferedState
Reactivity has taken a dominant position today within web app development. Our components and app state are all reactive, and the world has adapted–most would argue, for the better. But has Convex gone too far? 😉 A new generation of serverless backends like Convex is recklessly spreading reactivity across our databases, server-side functions, and protocols, making global reactivity a new phenomenon. Shared global data is becoming reactive by default. Is this good for the world? In this video, Jamie Turner explores one circumstance where this pervasive reactivity poses a challenge, and he builds one useful abstraction for taming over-reactivity and turning it back into a strength.
