vuex 2.3.0 的發布說明: Modules can now declare state using a function - this allows the same module definition to be reused (e.g. multiple times in the same store, or in multiple stores)
假如你 vuex 的模塊有多個格式是完全一樣的, 這時候就可以把這個模塊公共出來, 在 Vuex 實例里引用, 如:
import api from '~api'const actions = { async ['get']({commit, rootState: {route: { path }}}, config = {}) { const { data: { code, data } } = await api.post(config.url, config.data) if (code === 1001) commit('receive', data) }}const mutations = { ['receive'](state, data) { state.data = [].concat(data) }, ['modify'](state, payload) { const index = state.data.findIndex(item => item.id === payload.id) if (index > -1) { state.data.splice(index, 1, payload) } }, ['insert'](state, payload) { state.data = [payload].concat(state.data) }, ['remove'](state, id) { const index = state.data.findIndex(item => item.id === id) state.data.splice(index, 1) }}const getters = { ['get'](state) { return state.data }}export const _actions = actionsexport const _mutations = mutationsexport const _getters = gettersexport default { namespaced: true, actions, mutations, getters}import Vue from 'vue'import Vuex from 'vuex'import lists from './general/lists'Vue.use(Vuex)export default new Vuex.Store({ namespaced: true, modules: { base: { namespaced: true, modules: { app: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }}, platform: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }}, product: { namespaced: true, modules: { category: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }}, } }, keyword: { namespaced: true, modules: { username: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }}, } }, } }, buzz: { namespaced: true, modules: { shop: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }}, } }})但是 state 卻需要每個單獨設置, 如果直接設置在lists里, 會導致 state 對象被引用共享
