umi Bundler Utilities

This package, `@gmi/bundler-utils`, is an internal utility within the UmiJS monorepo, a React framework for enterprise-level applications. It provides core functionalities and abstractions related to bundler configuration and processing, primarily supporting `umi` itself and its `utoopack` bundler. While the package itself shows a version of `1.0.16-alpha.0`, its development actively tracks the main `umi` framework's releases, which are currently around `v4.6.x`. Given its internal nature and the absence of a public README, it is not intended for direct consumption by end-users. Its key differentiators lie in its tight integration with `umi`'s plugin system and its role in features like HMR, PostCSS, Sass, and TailwindCSS support within the `umi` ecosystem.
