How to access Vuex module getters and mutations?

In Addition to the accepted answer I wanna provide you with a workarround for the getter which is missing in the answer.

Access namespaced getter

this.$store.getters['yourModuleName/someGetterMethod']

Dispatch namespaced

this.$store.dispatch('yourModuleName/doSomething')

Dispatch namespaced with params

this.$store.getters['yourModuleName/someGetterMethod'](myParam)

Conclusion The key is to handle the namespace like a file System like Justin explained.

Edit: found a nice library for handling vuex Store
In addition to the basic knowledge I'd like to add this vuex library as a nice addition for working effectivly and fast with the vuex store. https://github.com/davestewart/vuex-pathify .
It looks pretty interesting and cares much of the configuration for you and also allows you to handle 2waybinding directly with vuex.

** Edit: Thanks to the other Answers. Added Dispatching method with params for wholeness.

In your example it would be store.dispatch('products/clearWorkingData') you can think of actions/mutations as a file system in a way. The deeper the modules are nested the deeper in the tree they are.

so you could go store.commit('first/second/third/method') if you had a tree that was three levels deep.

As another addition to the accepted answer, if you need to pass parameter(s) to the getter (for instance to fetch a specific item from the store collection), you need to pass it as follows:

this.$store.getters['yourModuleName/someGetterMethod'](myParam)

I don't think I like this notation very much, but it is what it is - at least for the moment.

Try this approach!

getCounter(){
  return this.$store.getters['auth/getToken'];     
}

auth is my module name and getToken is my getter.

Using Vuex mapGetters and mapActions you can now do this pretty easily. But I agree, it still isn't very obvious in the documentation.

Assuming your store module 'products' has a getter called 'mostPopular' and an action called 'clearWorkingData':

<template>
 <div>
  <p>{{mostPopularProduct}}<p>
  <p><button @click="clearProductData">Clear data</button></p>
 </div>
</template>
<script>
import { mapGetters, mapActions } from "vuex";

export default {
 computed: mapGetters({
  mostPopularProduct: "products/mostPopular"
 }),
 methods: mapActions({
  clearProductData: "products/clearWorkingData"
 })
}
</script>

The mapGetters helper simply maps store getters to local computed properties:

    import { mapGetters } from 'vuex'

    export default {
  // ...
  computed: {
    // mix the getters into computed with object spread operator
    ...mapGetters([
      'doneTodosCount',
      'anotherGetter',
      // ...
    ])
  }
}
If you want to map a getter to a different name, use an object:

    ...mapGetters({
  // map `this.doneCount` to `this.$store.getters.doneTodosCount`
  doneCount: 'doneTodosCount'
})

You have to be aware of using namespaced: true when configuring particular store object
