Practice with no store actions |
6 |
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.
