npm包redux-storage-engine-electron-store使用教程

前言

作为前端开发者,经常需要将数据保存在本地。在使用Electron开发桌面应用的时候,可使用Electron的本地存储模块,但是它存在一个缺点,就是不能将数据保存在不同窗口间共享。为了解决这个问题,我们可以使用redux-storage-engine-electron-store包,将数据保存在本地的Electron Store中,方便在不同窗口间共享数据。

安装

运行以下命令安装redux-storage-engine-electron-store包:

npm install redux-storage-engine-electron-store --save

使用

使用redux-storage-engine-electron-store包的步骤如下:

第一步,创建save函数

save函数的作用是将Redux存储的状态保存到本地。我们可以使用redux-storage包来创建一个save函数,如下:

import createEngine from 'redux-storage-engine-electron-store';
import { createStore } from 'redux';
import { persistStore, persistReducer } from 'redux-persist';
import storage from 'redux-persist/lib/storage';

const persistConfig = {
  key: 'root',
  storage,
};

const reducer = (state = {}, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { ...state, count: state.count + 1 };
    default:
      return state;
  }
};

const persistedReducer = persistReducer(persistConfig, reducer);

const engine = createEngine();
const store = createStore(persistedReducer);
const persistor = persistStore(store, { engine });

第二步,使用save函数

在需要保存数据的地方,使用save函数将Redux存储的状态保存到本地。使用persistor.persist()方法来调用save函数。

store.dispatch({ type: 'INCREMENT' });
persistor.persist();

示例代码

完整的示例代码如下:

import createEngine from 'redux-storage-engine-electron-store';
import { createStore } from 'redux';
import { persistStore, persistReducer } from 'redux-persist';
import storage from 'redux-persist/lib/storage';

const persistConfig = {
  key: 'root',
  storage,
};

const reducer = (state = {}, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { ...state, count: state.count + 1 };
    default:
      return state;
  }
};

const persistedReducer = persistReducer(persistConfig, reducer);

const engine = createEngine();
const store = createStore(persistedReducer);
const persistor = persistStore(store, { engine });

store.dispatch({ type: 'INCREMENT' });
persistor.persist();

结语

使用redux-storage-engine-electron-store包可以很方便地将Redux存储的状态保存到本地的Electron Store中。本文介绍了如何安装和使用redux-storage-engine-electron-store包,并提供了示例代码。希望本文对您有所帮助。
