j2v – Jest to Vitest Migration CLI

j2v (v0.1.2) is a CLI tool that automates migration from Jest to Vitest for JavaScript/TypeScript projects. It converts Jest configuration to Vitest, generates setup files, and removes Jest dependencies. Releases are occasional. Key differentiators: evaluates Jest config at conversion time (handles derived values), supports globals option, and provides a compatibility list of supported APIs. Limitations: CommonJS setup files break, and code style may not be preserved.
