Reviewer scorecard
“The best local development experience for edge functions. Miniflare emulates the entire Cloudflare platform locally.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Local emulation of D1, R2, KV, and Durable Objects means you develop at full speed without deploys.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Local-first development tools for edge platforms will become the standard. Wrangler leads this pattern.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
