How to access the getter from another vuex module?

Question

Within a vuex getter I know it is possible to access the state from another vuex module like so:

pages: (state, getters, rootState) => {
    console.log(rootS

If you want to access global/namespaced getter from the module, Here is how you can it,

getters: {
    // `getters` is localized to this module's getters
    // you can use rootGetters via 4th argument of getters
    someGetter (state, getters, rootState, rootGetters) {
        rootGetters.someOtherGetter //'someOtherGetter' global getter
        rootGetters['bar/someOtherGetter'] //'bar/someOtherGetter' namespaced getter
    },
    ...
},

Here is the way to access actions, Also includes usage of action and mutations for the reference.

actions: {
      // dispatch and commit are also localized for this module
      // they will accept `root` option for the root dispatch/commit
      someAction ({ dispatch, commit, getters, rootGetters }) {
      
        rootGetters.someGetter //'someGetter' global getter
        rootGetters['bar/someGetter'] //'bar/someGetter' namespaced getter

        dispatch('someOtherAction') //'someOtherAction' local action
        dispatch('someOtherAction', null, { root: true }) //'someOtherAction' namespaced action

        commit('someMutation') //'someMutation' local mutation
        commit('someMutation', null, { root: true }) //'someMutation' namespaced mutation
      },
      ...
    }
  }

Had to dig through the documentation but I found it:

https://vuex.vuejs.org/en/api.html

(Ctrl+F search for RootGetters on that page)

My code becomes:

pages: (state, getters, rootState, rootGetters) => {}

Beware that all rootGetters are global and you no longer use it like rootState where you would prefix the state by the module name.

You simply call a getter from another module like so:

rootGetters.activeFilters

Hopefully this will help someone out in the future who is running into this as well.
