Encountering an unfamiliar action type when using Vuex mapAction

I'm still learning the ropes of Vuex and I've encountered an issue while using mapActions to retrieve data from my store and display it in my component's template. The error

[vuex] unknown action type: getItemDetail
keeps popping up, but I can't figure out why.

The action I'm trying to dispatch in my store is called getItemDetail. Here's a snippet of my full store:

import fetch from './fetch';

const url = 'items';

const defaults = {
  id: '',
  rating: '',
  type: '',
};

const state = { ...defaults, };

const getters = {};

const actions = {
  getItemDetail ({ commit, }, itemId) {
    fetch.get(`${url}/${itemId}`).then((response) => {  
      commit('setItemDetail', { ...defaults, ...response.data, });
    });
  },
};

const mutations = {
  setItemDetail (state, item) {
    state.item = item;
  },
};

export default {
  namespaced: true,
  state,
  getters,
  actions, 
  mutations,
};


In my component, the code looks like this:

<template>
  <div>
    <p> {{ itemDetail }} </p>
  </div>
</template>

<script>
import { mapActions } from 'vuex';
export default {

  computed: {
    itemDetail () {
      this.getItemDetail('23451');
      return this.$store.state;
    },
  },
  methods: {
    ...mapActions([
      'getItemDetail',
    ]),
  },
};
</script>

I would greatly appreciate any help with this!

Answer №1

Based on the code you provided, it appears that you are working within a namespaced store module.

To interact with a namespaced action in your store, you will need to map it using the module name as the first parameter (this applies to mapState and mapGetter as well) :

methods: {
  ...mapActions("yourModuleName", [
    'getItemDetail',
  ]),
},
