vuex unknown action (or mutation) type - vuex

Question

I'm writing a simple code to set token in store in an Nuxt application. when I tried to call a mutation or action from my store, this error is logged in console: [vuex] unknown action type: setToken
import Vuex from 'vuex';
export const store = new Vuex.Store({
state:()=> ({
token: ''
}),
getters: {
getToken: state => {
return state.token;
}
},
mutations: {
setToken: (tokenStr) => {
state.token = tokenStr;
}
},
actions: {
setToken: ({ commit }, tokenStr) => {
commit('setToken', tokenStr);
}
}
})
This is a method trying to call the mutation:
methods:{
setToken(){
this.$store.dispatch('setToken','token1');
this.token = this.$store.getters.token;
}
}

Answer 1

You are using the 'classic' and now deprecated method of setting the vuex store in nuxt. You should set it up like this:
// store/index.js
export const state = () => ({
token: ''
})
export const mutations = {
SET_TOKEN (state, tokenStr) {
state.token = tokenStr
}
export const actions = {
setToken ({ commit }, tokenStr) {
commit('SET_TOKEN', tokenStr)
}
}
export const getters = {
token: (state) => state.token
}
Nuxt will build the store for you from there. You can see it in the doc here.

You can dispatch actions in components with this.$store.dispatch('xxx'), or use the mapActions helper which maps component methods to store.dispatch calls (requires root store injection):
Try Another Method For Dispatching An Action
import { mapActions } from 'vuex'
export default {
// ...
methods: {
...mapActions([
'increment',
// map `this.increment()` to
this.$store.dispatch('increment')
// `mapActions` also supports payloads:
'incrementBy' // map `this.incrementBy(amount)` to `this.$store.dispatch('incrementBy', amount)`
]),
...mapActions({
add: 'increment' // map `this.add()` to `this.$store.dispatch('increment')`
})
}
}
