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。
