rollup-plugin-mock-imports

Rollup plugin (v1.0.8) for mocking ESM imports during bundling, using `__mocks__` directories (like Jest) or a custom `node_mockdules` folder. Designed for pre-compilation testing scenarios (e.g., Svelte components with JSDOM), it intercepts resolved module IDs before other Rollup plugins. Configuration options include `mockall`, `ignore`, and `mock` patterns. Requires Rollup ^0.66.6 as peer dependency. Ships TypeScript types. Release cadence: low (last updated 2019).
