esbuild-plugin-babel-cached

esbuild-plugin-babel-cached (v0.2.3) is an esbuild plugin that runs files through Babel for transforms not supported natively by esbuild, with built-in caching. It wraps @babel/core and allows configuration via babel.config.json or inline options. Unlike other esbuild Babel plugins, it caches results to speed up rebuilds. The plugin is stable with weekly releases and is intended for scenarios where esbuild's own transforms (e.g., newer JavaScript/TypeScript) are insufficient and you need Babel for specific presets or plugins (e.g., for legacy browser support or custom transforms). It depends on @babel/core as a peer dependency and is ESM-only.
