"Encountering an undefined rawModule error while transitioning from a single module to multiple modules in Vuex

I recently transitioned my project from a single module in Vuex store to multiple modules as per the documentation.

The documentation explains how to access a specific module's state like this:

store.state.a // -> `moduleA`'s state

However, it fails to provide clear instructions on accessing getters, mutations, or commands like 'commit' and 'replaceState' for a specific module. Based on this, I made my own assumptions:

store.getters.a
store.mutations.a
store.a.commit()
store.a.replaceState()

1) Do you think these assumptions are correct?

2) When trying to use these methods, I encountered a vague error message:

TypeError: rawModule is undefined

Below is an excerpt from my store.js file:

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
  modules: {
    listingModule: listingModule,
    openListingsOnDashModule: listingsOnDashModule,
    closedListingsOnDashModule: listingsOnDashModule
  }
})

const listingsOnDashModule = {...}
const listingModule = {...}
// Their content remains unchanged from the single module approach.

Answer №1

The issue at hand:

TypeError: rawModule is not defined

arises when attempting to register a module that is undefined. Chances are, you inadvertently imported undefined while registering the module.

The syntax for store.state.a is correct. However, unless specifically specifying a namespace, the part after .a should be omitted in general.
