vite-plugin-mock-replace

Vite plugin (0.0.3, early development) that replaces source files with mock implementations during testing (vitest, Storybook). Supports extension-based (my-file.ts → my-file.mock.ts) and directory-based (__mocks__/my-file.ts) overrides. Requires vite >=5.0.0 and vitest >=1.0.0 as peer dependencies. Lightweight alternative to manual module mocking with zero-config auto-resolution.
