vite-legacy-interop

A Vite 8 plugin that wraps legacy CJS subpath imports in ESM-compatible virtual modules to prevent runtime interop errors. Current version 1.0.4, actively maintained. Designed for Vite 8 and Rolldown, it intercepts imports like `legacy-lib/lib/Button` and replaces them with virtual ESM wrappers that handle CJS-to-ESM interop, solving `SyntaxError` and `ReferenceError` at runtime. Differentiators: targeted at Vite 8 with Rolldown, supports multiple libraries and nested subpaths, minimal configuration, includes debug logging.
