VueUsecreateGlobalState
Keep states in the global scope to be reusable across Vue instances.
Demo
name: 'Banana'
color: 'Yellow'
size: 'Medium'
Usage
Without Persistence (Store in Memory)
js
// store.js
import { ref } from 'vue'
import { createGlobalState } from '@vueuse/core'
export const useGlobalState = createGlobalState(
() => {
const count = ref(0)
return { count }
}
)
// store.js
import { ref } from 'vue'
import { createGlobalState } from '@vueuse/core'
export const useGlobalState = createGlobalState(
() => {
const count = ref(0)
return { count }
}
)
A bigger example:
js
// store.js
import { computed, ref } from 'vue'
import { createGlobalState } from '@vueuse/core'
export const useGlobalState = createGlobalState(
() => {
// state
const count = ref(0)
// getters
const doubleCount = computed(() => count.value * 2)
// actions
function increment() {
count.value++
}
return { count, doubleCount, increment }
}
)
// store.js
import { computed, ref } from 'vue'
import { createGlobalState } from '@vueuse/core'
export const useGlobalState = createGlobalState(
() => {
// state
const count = ref(0)
// getters
const doubleCount = computed(() => count.value * 2)
// actions
function increment() {
count.value++
}
return { count, doubleCount, increment }
}
)
With Persistence
Store in localStorage with useStorage():
js
// store.js
import { createGlobalState, useStorage } from '@vueuse/core'
export const useGlobalState = createGlobalState(
() => useStorage('vueuse-local-storage', 'initialValue'),
)
// store.js
import { createGlobalState, useStorage } from '@vueuse/core'
export const useGlobalState = createGlobalState(
() => useStorage('vueuse-local-storage', 'initialValue'),
)
js
// component.js
import { useGlobalState } from './store'
export default defineComponent({
setup() {
const state = useGlobalState()
return { state }
},
})
// component.js
import { useGlobalState } from './store'
export default defineComponent({
setup() {
const state = useGlobalState()
return { state }
},
})
