Currently, dependencies like broker and h are often treated as globals or singletons. Implementing a proper Dependency Injection (DI) container would make the code more testable and modular.
The DOMReconciler performs a basic diff. Adopting a more robust virtual DOM algorithm (like Snabbdom or Preact's reconciler) could improve performance for large updates.
Ensure that the build process (e.g., Webpack or Rollup) can effectively tree-shake unused modules. The modular structure is a good start, but verify that side-effects are minimized.
Migrating to TypeScript would add type safety, improve developer experience with autocompletion, and catch errors at compile time.
Add a comprehensive unit test suite using Jest or Vitest. The modular structure makes it easier to test individual components and classes in isolation.
Consider a more centralized state management solution (like Redux or MobX patterns) if the application grows complex, although the current State class provides a good reactive primitive.
Evaluate wrapping OpenScript components as standard Web Components (Custom Elements) for better interoperability with other frameworks.
Integrate a CSS-in-JS solution or scoped CSS to handle component styling more effectively than inline styles or global CSS.
