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.

Building a Multiplayer Game
Building multiplayer games requires a lot of synchronization logic and event systems. However, using Convex, we get a lot of this for free! Follow along here as we build a complex multiplayer game on Convex, leveraging its reactive-by-default queries, transactional mutations, backend storage, and scheduled functions.

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.

Intro to Convex Query Performance
How do I ensure my Convex database queries are fast and efficient? When should I define an index? What is an index? This document explains how you should think about query performance in Convex by describing a simplified model of how queries and indexes function.

Backend Matters (Making Fast5 #2)
Why does anything really need to run on the server anymore? And even if it does, do I, the developer, need to be so involved? Yes! Even in a serverless world, the backend computing context being a real, discrete environment that you have control and influence over is not only necessary but hugely beneficial.

Introducing Fast5
At Convex, we're creating a platform for managing global state for web developers. Unsurprisingly, we've found one of the best ways to improve our platform is to actually build stuff with it!
