vuex 2.3.0 的发布说明: 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 的模块有多个格式是完全一样的,这时候就可以把这个模块公共出来,在 Vuex 实例里引用,如:
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 = [].concat(data)
},'modify' {
const index = state.data.findIndex(item => item.id === payload.id)
if (index > -1) {
state.data.splice(index,1,payload)
}
},'insert' {
state.data = [payload].concat(state.data)
},'remove' {
const index = state.data.findIndex(item => item.id === id)
state.data.splice(index,1)
}
}
const getters = {
'get' {
return state.data
}
}
export const _actions = actions
export const _mutations = mutations
export const _getters = getters
export default {
namespaced: true,actions,mutations,getters
}
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,product: {
namespaced: true,modules: {
category: {...lists,}
},keyword: {
namespaced: true,modules: {
username: {...lists,}
},buzz: {
namespaced: true,modules: {
shop: {...lists,}
}
})
但是 state 却需要每个单独设置,如果直接设置在lists里,会导致 state 对象被引用共享
在 vuex@2.3.0 中,这个问题将不存在
async ['get']({commit,state() {
return { lists: { data: [],current_page: 1 } }
},getters
}
import lists from './general/lists'Vue.use(Vuex)
export default new Vuex.Store({
namespaced: true,modules: {
app: lists,platform: lists,modules: {
category: lists,modules: {
username: lists,modules: {
shop: lists,}
}
})
