I try to store drawer data in VueX to use it on external component.
My console error: [vuex] unknown action type: app/switchDrawer
pages/test.vue
<template>
<v-navigation-drawer v-model="drawer" app>
<v-list dense>
...
</v-list>
</v-navigation-drawer>
</template>
<script>
export default {
computed: {
drawer: {
get () {
return this.$store.state.app.drawer
},
set (value) {
console.log(value);
return this.$store.dispatch('app/toggleDrawer', value)
}
}
}
}
</script>
The console.log() function give me lot of lines in loop in console.
I'd like to use too the mapGetters class from VueX instead computed get/set:
computed: mapGetters({
drawer: 'app/drawer'
})
I've an error in console:
[Vue warn]: Computed property "drawer" was assigned to but it has no setter.
store/app.js
export const state = () => ({
drawer: true
})
export const getters = {
drawer: state => state.drawer
}
export const mutations = {
TOGGLE_DRAWER: (state) => {
state.drawer = !state.drawer
}
}
export const actions = {
toggleDrawer ({ commit }, value) {
commit('TOGGLE_DRAWER', value)
}
}
Found your problem - a computed setter has to have no return statement.
drawer: {
get () {
return this.$store.state.app.drawer
},
set (value) {
this.$store.dispatch('app/toggleDrawer', value)
}
}
Please notice that your action submits a value to the mutation which dosen't take any value. So better add a new mutation that handles said value:
export const mutations = {
SET_DRAWER: (state, value) => {
state.drawer = value
}
}
export const actions = {
toggleDrawer ({ commit }, value) {
commit('SET_DRAWER', value)
}
}
