Reviewer scorecard
“Real-time reactivity without WebSocket boilerplate. Server functions co-located with schema definition is elegant.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“The DX is genuinely excellent. If your app needs real-time, Convex eliminates an enormous amount of complexity.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Reactive backends that push data to clients will become the default. Convex is building that future now.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
