Practice with no store actions	7

The recommended usage is to colocate actions and states within the store (let your actions be located together with your state).

For example:

export const useBoundStore = create((set) => ({
  count: 0,
  text: 'hello',
  inc: () => set((state) => ({ count: state.count + 1 })),
  setText: (text) => set({ text }),
}))

This creates a self-contained store with data and actions together.

---

An alternative approach is to define actions at module level, external to the store.

export const useBoundStore = create(() => ({
  count: 0,
  text: 'hello',
}))

export const inc = () =>
  useBoundStore.setState((state) => ({ count: state.count + 1 }))

export const setText = (text) => useBoundStore.setState({ text })

This has a few advantages:

• It doesn't require a hook to call an action;
• It facilitates code splitting.

While this pattern doesn't offer any downsides, some may prefer colocating due to its encapsulated nature.
