# createGlobalState
|
|
|
|
Keep states in the global scope to be reusable across Vue instances.
|
|
|
|
## Usage
|
|
|
|
### Without Persistence (Store in Memory)
|
|
|
|
```ts
|
|
// store.ts
|
|
import { createGlobalState } from '@vueuse/core'
|
|
import { shallowRef } from 'vue'
|
|
|
|
export const useGlobalState = createGlobalState(
|
|
() => {
|
|
const count = shallowRef(0)
|
|
return { count }
|
|
}
|
|
)
|
|
```
|
|
|
|
A bigger example:
|
|
|
|
```ts
|
|
// store.ts
|
|
import { createGlobalState } from '@vueuse/core'
|
|
import { computed, shallowRef } from 'vue'
|
|
|
|
export const useGlobalState = createGlobalState(
|
|
() => {
|
|
// state
|
|
const count = shallowRef(0)
|
|
|
|
// getters
|
|
const doubleCount = computed(() => count.value * 2)
|
|
|
|
// actions
|
|
function increment() {
|
|
count.value++
|
|
}
|
|
|
|
return { count, doubleCount, increment }
|
|
}
|
|
)
|
|
```
|
|
|
|
### With Persistence
|
|
|
|
Store in `localStorage` with `useStorage`:
|
|
|
|
```ts twoslash include store
|
|
// store.ts
|
|
import { createGlobalState, useStorage } from '@vueuse/core'
|
|
|
|
export const useGlobalState = createGlobalState(
|
|
() => useStorage('vueuse-local-storage', 'initialValue'),
|
|
)
|
|
```
|
|
|
|
```ts
|
|
// @filename: store.ts
|
|
// @include: store
|
|
// ---cut---
|
|
// component.ts
|
|
import { useGlobalState } from './store'
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
const state = useGlobalState()
|
|
return { state }
|
|
},
|
|
})
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export type CreateGlobalStateReturn<Fn extends AnyFn = AnyFn> = Fn
|
|
/**
|
|
* Keep states in the global scope to be reusable across Vue instances.
|
|
*
|
|
* @see https://vueuse.org/createGlobalState
|
|
* @param stateFactory A factory function to create the state
|
|
*
|
|
* @__NO_SIDE_EFFECTS__
|
|
*/
|
|
export declare function createGlobalState<Fn extends AnyFn>(
|
|
stateFactory: Fn,
|
|
): CreateGlobalStateReturn<Fn>
|
|
```
