vite-plugin-istanbul
JSON →Vite plugin that instruments source code with Istanbul/NYC for code coverage, similar to Webpack's istanbul-instrumenter-loader. Current stable version 8.0.0 (released March 2026) supports Vite >=4. Maintained by community with regular releases. Key differentiator: seamless integration with Vite's build pipeline, automatic TypeScript/JSX/Vue support, and optional environment variable gating to avoid instrumenting production builds. Designed for development/test coverage only.
