Reviewer scorecard
“Real-time reactivity without WebSocket boilerplate. Server functions co-located with schema definition is elegant.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“The DX is genuinely excellent. If your app needs real-time, Convex eliminates an enormous amount of complexity.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Reactive backends that push data to clients will become the default. Convex is building that future now.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
