带有vuex模块装饰器的nuxtServerInit

Question

在Nuxt中使用这种方法：https://github.com/championswimmer/vuex-module-decorators#accessing-modules-with-nuxtjs

store/index.ts：

import { Store } from 'vuex'
import { initialiseStores } from '~/utils/store-accessor'

const initializer = (store: Store<any>) => initialiseStores(store)

export const plugins = [initializer]
export * from '~/utils/store-accessor'

utils/store-accessor.ts：

import { Store } from 'vuex'
import { getModule } from 'vuex-module-decorators'
import settingsModule from '~/store/settingsModule'

// eslint-disable-next-line
let settingsStore: settingsModule

// noinspection JSUnusedGlobalSymbols
function initialiseStores(store: Store<any>): void {
  settingsStore = getModule(settingsModule, store)
}

export { initialiseStores, settingsStore }

store/settingsModule.ts：

import { Action, Module, Mutation, VuexModule } from 'vuex-module-decorators'

@Module({
  name: 'settingsModule',
  namespaced: true,
  stateFactory: true
})
export default class settingsModule extends VuexModule {
  public videos: any[] = []

  @Mutation
  public SAVE_VIDEOS(value: any) {
    this.videos = value
  }

  @Action({ commit: 'SAVE_VIDEOS' })
  public saveVideos(value: any) {
    return value
  }

  // noinspection JSUnusedGlobalSymbols
  get videosArray() {
    return this.videos
  }
}

我如何调用nuxtServerInit()呢？如果我在“store/index.ts”中尝试：

export const actions: ActionTree<any, any> = {
  async nuxtServerInit({ dispatch }) {
    await dispatch('settingsModule/saveVideos', [1, 2, 3, 4, 5], { root: true })
  }
}

当我加载我的web-app时，nuxt没有触发动作调度。

store/index.ts

// https://github.com/championswimmer/vuex-module-decorators#accessing-modules-with-nuxtjs
import { Store } from "vuex";
import { Context } from "@nuxt/types";
import { initialiseStores } from "~/utils/store-accessor";
export * from "~/utils/store-accessor";

export const actions = {
    nuxtServerInit(store: Store<any>, context:Context) {
        console.log(store);
        console.log(context);
    }
};
const initializer = (store: Store<any>) => initialiseStores(store);
export const plugins = [initializer];

const声明的顺序会有所不同

utils/store-accessor.ts

/* eslint-disable import/no-mutable-exports */
// https://github.com/championswimmer/vuex-module-decorators#accessing-modules-with-nuxtjs
import { Store } from "vuex";
import { getModule } from "vuex-module-decorators";
import HarmonyStoreModule from "~/store/harmony";

let harmonyStore: HarmonyStoreModule;

function initialiseStores(store: Store<any>): void {
    harmonyStore = getModule(HarmonyStoreModule, store);
}

export { initialiseStores, harmonyStore };

确保您正在初始化您的存储：

import { Store } from "vuex";
import {initialiseStores, settingsStore } from "~/utils/store-accessor";

const initializer = (store: Store<any>) => initialiseStores(store);
export const plugins = [initializer];
export * from "~/utils/store-accessor";

export const actions = {
  async nuxtServerInit({}, ctx) {

// do it once more like so.. 
    initialiseStores(ctx.store);

// now just import stores from utils..
    settingsStore.saveVideos([1, 2, 3, 4, 5])

// NOTE: 
now all server side functions (asyncData, fetch etc..) will work without the need 
for you to initialize stores only because nuxtServerInit is the very first function 
called once server side. You'll need to call initialiseStores(ctx.store) once more client
side for everything to work (client side) correctly. I suggest using the module
nuxtClientInit and do the same.
