[Vuex] Suppress prefix or suffix in the module definition

module.js

// use shorter name in local
const ADD = `ADD_TOAST_MESSAGE`
const REMOVE = `REMOVE_TOAST_MESSAGE`

// export as longer name with suffix
export {
  ADD as ADD_TOAST_MESSAGE,
  REMOVE as REMOVE_TOAST_MESSAGE
}

const actions = {
  [ADD] ({ commit }, text) {
    const id = ++maxToastId

    commit(ADD, createMessage(id, text))

    setTimeout(() => {
      commit(REMOVE, id)
    }, 5000)
  },

  [REMOVE] ({ commit }, id) {
    commit(REMOVE, id)
  }
}

const mutations = {
  [ADD] (state, data) {
    state.messages.push(data)
  },

  [REMOVE] (state, id) {
    state.messages = state.messages.filter(m => m.id !== id)
  }
}

export default {
  state,
  actions,
  mutations
}
