Using constants naming in vuex store

Hello community, I have been assigned to a new project using vuex, the store is modular, and they use constants naming style in all their state getters actions etc.
e.g.:
store-types.js : export const AUTH = ‘AUTH’;
auth.js module: const state = { [ S.AUTH ]: {},}
const getters = { [ S.AUTH ] (state) {
return state.[S.AUTH];
}}
const mutation= {[S.SET_AUTH](state, data) {
state.[S.AUTH] = data;
},}
const action= {
[S.GET_AUTH] ({commit}) {some code}}

my question is how can i use the getter for example in my component, and dispatch the action and so forth??
S refering to store-types
