Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Server Components, streaming, and the App Router represent the future of React. The Vercel deployment experience is unmatched.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Some complexity with the App Router learning curve, but it's the most complete full-stack React framework.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Next.js defines how modern web apps are built. Server Components and AI SDK integration make it the platform for AI web apps.”
