electron之旅(二)react使用

首先使用react模板

我们这里使用的是vite和yarn

yarn create vite #创建vite的react-js模板

初始化依赖

yarn

添加依赖

state(状态管理)

yarn add redux react-redux

routes(react路由)

yarn add react-router-dom

electron依赖

yarn add electron vite-plugin-electron cross-env -D

修改&添加文件

创建(根目录(与src同级))\electron/index.js

import { app, BrowserWindow } from "electron";
import path from "path";const createWindow = () => {const win = new BrowserWindow({webPreferences: {// 允许渲染进程使用nodecontextIsolation: false,nodeIntegration: true,},});// app.isPackaged 字段存在bug，即使正常打包后，仍然为false，所以不能用来判断项目是否经过打包if (process.env.NODE_ENV === 'development') {// 开发环境// process.env.VITE_DEV_SERVER_URL获取开发服务器的url// vite版本不同，VITE_DEV_SERVER_URL字段也有所变化，打印process.env查找具体的名称win.loadURL(process.env.VITE_DEV_SERVER_URL);} else {// 生产环境win.loadFile(path.join(__dirname, "../dist/index.html"));}
};app.whenReady().then(createWindow)

package.json

{"name": "electron_react_js_test01","private": true,"version": "0.0.0","type": "commonjs",//修改"main": "dist-electron/index.js",//添加"scripts": {"dev": "cross-env NODE_ENV=development vite",//修改"build": "vite build","preview": "vite preview"},...
}

vite.config.js

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'import electron from "vite-plugin-electron"//添加// https://vitejs.dev/config/
export default defineConfig({plugins: [react(),//添加electron({entry: 'electron/index.js'})],
})

yarn dev #即可

react状态管理&react路由

store.js

import {legacy_createStore} from "redux"//当然里面的数据自定义,这里只是一个参照
const defaultState = {num:0,isHome:false
}const reducer = (state = defaultState,action = {type,data}) =>{//深拷贝let newState = JSON.parse(JSON.stringify(state))//当然里面的数据自定义,这里只是一个参照switch(action.type){case "returnHome":newState.isHome = truebreakcase "QiTaPage":newState.isHome = falsebreakdefault:break}return newState
}const store = legacy_createStore(reducer)export default store

routes.jsx

import { Navigate } from "react-router-dom"
import Master from "./pages/master/Master"
import Home from "./pages/master/home/Home"
import Anime from "./pages/master/anime/Anime"const routes = [{path: '/master',element: <Master />,children: [{path: 'home',element: <Home />},{path: 'anime',element: <Anime />}]}
]export default routes

main.jsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App'
import './index.css'
import { Provider } from 'react-redux'
import { HashRouter } from 'react-router-dom'
import store from './store'ReactDOM.createRoot(document.getElementById('root')).render(<Provider store={store}><HashRouter><App /></HashRouter></Provider>
)

./src/App.jsx

渲染进程react和主进程通讯

渲染进程(以创建窗口为例)

import {useState, useEffect} from "react"
import { useSelector,useDispatch } from "react-redux"import { ipcRenderer } from "electron"//主要引入import anime from './anime.module.css'function Anime(props){return (<div className={anime.all}>{/*主要*/}<button onClick={()=>ipcRenderer.send('new-win')}>点击新页面</button></div>)
}export default Anime

主进程(以创建窗口为例)

import { app, BrowserWindow, ipcMain } from "electron";
import path from "path";const createWindow = () => {const win = new BrowserWindow({...});//添加ipcMain.on('new-win',()=>{const newWin = new BrowserWindow({width:300,height:250,webPreferences: {// 允许渲染进程使用nodecontextIsolation: false,nodeIntegration: true,},})newWin.loadURL("https://www.bilibili.com") //可以自行修改})
....

问题1

TypeError: path.join is not a function

解决

yarn add vite-plugin-electron-renderer

vite.config.js

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'import electron from "vite-plugin-electron"import electron_render from "vite-plugin-electron-renderer" //添加
// https://vitejs.dev/config/
export default defineConfig({plugins: [react(),electron({entry: 'electron/index.js'}),electron_render()//添加],
})
