Reviewer scorecard
“Component isolation done right. Independent versioning and testing per component is how design systems should work.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“The learning curve is steep and the tooling has rough edges. Storybook + npm packages achieve 80% of the value.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Component discovery and documentation are excellent. Designers can browse and understand available components easily.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
