**Summary:** `babel-plugin-mockable-imports` is a Babel plugin that transforms JavaScript modules to enable mocking of their ES and CommonJS imports in tests. It adds an `$imports` object to each module with `$mock` and `$restore` methods, allowing tests to temporarily replace dependencies with stubs or fakes. The plugin works with any test runner, bundler, and environment (Node or browser), and supports both JavaScript and TypeScript. **Who it's for:** This plugin is designed for developers writing unit tests who need fine-grained control over module dependencies, especially when testing code that imports from external or internal modules. It's particularly useful for projects using Babel to transpile code and wanting a lightweight, efficient way to mock imports without the overhead or limitations of alternatives like proxyquire.
