Vue TSX Type Support

vue-tsx-support is a TypeScript support library designed to enable and enhance the use of TSX (JSX for TypeScript) within Vue 2 applications. Currently at version 3.2.0, this package primarily functions as a type checker, providing robust type safety for JSX syntax used in Vue 2 components. It is crucial to note that vue-tsx-support does not handle JSX transpilation; users must integrate a separate Babel preset (such as `@vue/babel-preset-jsx`) for this purpose. A key differentiator is its explicit focus on the Vue 2 ecosystem; it does not support Vue 3, which incorporates its own JSX type checking mechanisms that are incompatible. The library supports various component styles, including object-style, class-style (with `vue-class-component`), and `@vue/composition-api`, with specific instructions for each. The project is largely in a maintenance phase, as its core functionality is tied to the now older Vue 2 major version.
