Bright ideas and techniques for building with Convex.

Reactivity

Can your database do this? Ep. 1: Magic caching
With Convex's magic query cache, Convex's powerful subscriptions are cached, not merely values. So you get fast, jank-free renders with no cache consistency or invalidation headaches.

GPT Streaming With Persistent Reactivity
Stream GPT responses without brittle browser-based HTTP streaming. Multiplayer reactivity, persistence, reactivity via Convex. Using OpenAI’s Node SDK server-side, and Convex's useQuery hook client-side.

Help, my app is overreacting!
Reactive backends like Convex make building live-updating apps a cinch, but default behavior might be too reactive for some use cases. Not to worry! Let’s fine-tune the reactive dataflow of a Convex + React app to deliver a better UX.

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!

The serverless revolution deserves more than just a serverless database
The serverless movement has eliminated so many problems but it has left application developers with the hardest one of all: managing distributed state.

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.

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.

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.

Convex vs. Relational Databases
Relational databases are powerful tools for persisting data, but using them to build interactive web apps requires a lot of work. A web app architecture built on a relational database is an entire cluster of databases, backends, caching nodes, and Pub/Sub servers. And even after you invest in all of that infrastructure you'll still need to explicitly define your database schema upfront and write cumbersome SQL queries. At Convex we believe that web developers shouldn't have to worry about any of this. We can handle the servers, caching, and reactivity and you can focus on your product.

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.
