Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Stateful edge servers are the right abstraction for real-time. The Cloudflare acquisition ensures long-term viability.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Durable Objects made simple. For real-time features without WebSocket infrastructure complexity, PartyKit is excellent.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Edge-first real-time infrastructure is the future of multiplayer applications. PartyKit is building that.”
