persist.ts   可存储到本地

import { PersistedStateOptions } from "pinia-plugin-persistedstate";

/**
 * @description pinia 持久化参数配置
 * @param {String} key 存储到持久化的 name
 * @param {Array} paths 需要持久化的 state name
 * @return persist
 * */
const piniaPersistConfig = (key: string, paths?: string[]) => {
  const persist: PersistedStateOptions = {
    key,
    storage: localStorage,
    // storage: sessionStorage,
    paths
  };
  return persist;
};

export default piniaPersistConfig;

index.ts

import { createPinia } from "pinia";
import piniaPluginPersistedstate from "pinia-plugin-persistedstate";

// pinia persist
const pinia = createPinia();
pinia.use(piniaPluginPersistedstate);

export default pinia;

main.ts导入

import pinia from "@/stores";

createApp(App).use(pinia)

使用：

存储数据：general.ts

import { defineStore } from "pinia";
import piniaPersistConfig from "@/stores/helper/persist";

interface GeneralType {
  linesName: string;
}
export const useGeneralStore = defineStore({
  id: "live-General",
  state: (): GeneralType => ({
    linesName: "全部"
  }),
  getters: {},
  actions: {
    // Set setGeneral
    setGeneral(linesName: string) {
      this.linesName = linesName;
    }
  },
  persist: piniaPersistConfig("live-linesName")  // 持久化操作
});

修改数据：

import { useGeneralStore } from "@/stores/modules/general";
const generalStore = useGeneralStore();

generalStore.setGeneral(linesName.value);

直接使用：generalStore.linesName

监听piain中的数据更新：数据变化就会触发

generalStore.$subscribe((linesNames, state) => {
  console.log(linesNames, state);
});
