gemini-cli - 💡(How to fix) Fix Massive AppContainer component leads to poor maintainability and architectural fragility [1 comments, 2 participants]

What happened?

AppContainer.tsx is nearly 3000 lines long, managing dozens of top-level states, effects, and complex business logic (auth, themes, history, terminal setup, background tasks).

What did you expect to happen?

The component should be refactored into smaller, logically grouped components or custom hooks using a state management pattern (like useReducer) to decouple UI from business logic.

Anything else we need to know?

File: packages/cli/src/ui/AppContainer.tsx. The sheer size makes it prone to bugs and difficult to audit for side effects.
