Vue Runtime Helpers

vue-runtime-helpers is a utility package that provides internal runtime helpers crucial for the compilation and rendering of Vue Single File Components (SFCs). These helpers are primarily consumed by Vue build tools such as `vue-loader` for Webpack, `@vitejs/plugin-vue` for Vite, and older tools like `rollup-plugin-vue`. Its core functionalities include `normalizeComponent`, which standardizes component options for the Vue runtime, and `createInjector`, used for injecting component-scoped styles. While the package itself, currently at version 1.1.2, has not seen active development since its last release seven years ago, its underlying concepts and the problems it solves (like component normalization and style injection) remain integral to the Vue ecosystem's build pipeline. It is not intended for direct consumption by most application developers but rather serves as low-level plumbing, with its essential logic now absorbed or re-implemented within actively maintained Vue tooling. It does not follow an independent release cadence.
