6. Hierarchical internal modules

The Vue 3.0 core is still available through a simple <script> tag, but its internal structure has been completely rewritten as a set of decoupled modules. The new architecture provides better maintainability and allows end users to reduce runtime size by half through tree shaking.

The modules are as follows:

Function points provided by the module:

1. Compiler support for building Custom AST transformations (e.g., build-time i18n)

WebGL or Terminal) custom renderer. The default DOM renderer is built using the same API. 3. The functions exported by the @vue/reactivity module can directly access the Vue

reactive system and can be used as an independent package. It can be paired with other template solutions such as

lit-html and can even be used for non-UI scenarios. 7.composition-api design purpose

Aims to solve the difficulties of using Vue in large applications.
