Documentation by Seth Hobson

Small app, simple state → Zustand or Jotai
Large app, complex state → Redux Toolkit
Heavy server interaction → React Query + light client state
Atomic/granular updates → Jotai

// store/useStore.ts
import { create } from 'zustand'
import { devtools, persist } from 'zustand/middleware'

interface AppState {
  user: User | null
  theme: 'light' | 'dark'
  setUser: (user: User | null) => void
  toggleTheme: () => void
}

export const useStore = create<AppState>()(
  devtools(
    persist(
      (set) => ({
        user: null,
        theme: 'light',
        setUser: (user) => set({ user }),
        toggleTheme: () => set((state) => ({
          theme: state.theme === 'light' ? 'dark' : 'light'
        })),
      }),
      { name: 'app-storage' }
    )
  )
)

// Usage in component
function Header() {
  const { user, theme, toggleTheme } = useStore()
  return (
    <header className={theme}>
      {user?.name}
      <button onClick={toggleTheme}>Toggle Theme</button>
    </header>
  )
}

// Before (legacy Redux)
const ADD_TODO = "ADD_TODO";
const addTodo = (text) => ({ type: ADD_TODO, payload: text });
function todosReducer(state = [], action) {
  switch (action.type) {
    case ADD_TODO:
      return [...state, { text: action.payload, completed: false }];
    default:
      return state;
  }
}

// After (Redux Toolkit)
const todosSlice = createSlice({
  name: "todos",
  initialState: [],
  reducers: {
    addTodo: (state, action: PayloadAction<string>) => {
      // Immer allows "mutations"
      state.push({ text: action.payload, completed: false });
    },
  },
});

  Iterate on the Cardputer-Adv MicroPython app bundle (Claude Buddy, Snake, Hello) after the device is already provisioned via m5-onboard. Use when the user wants to add a new app, push a single changed .py without re-flashing, watch device serial logs, or run a one-shot REPL command. Trigger on "add an app", "push to the cardputer", "tail the device", "run on the device", or follow-up work after /maker-setup.
