Accessing rootState in Vuex getter

Question

How do you access rootState in getters?

const getters = {
  getParams: rootState => {
    return rootState.route.params
  },
}

Answer 1

If this getter is in a module rootState is the third arguments.

const getters = {
  getParams: (state, getters, rootState) => {
    return rootState.route.params
  }
}
