报错：TypeError: fs.existsSync is not a function
在React项目中引用
const electron = require('electron');
替换为：
const electron = window.require('electron');
同时需要加入webPreferences配置：
const win = new BrowserWindow({
width: 1000,
height: 800,
webPreferences: {
nodeIntegration: true,
contextIsolation: false,
enableRemoteModule: true
}
})
使用例子：
const electron = window.require('electron');
const { remote } = electron;
class ReactNative extends React.Component {
createOpenDialog = () => {
remote.dialog.showOpenDialog({
properties: ['openFile', 'openDirectory']
}).then(result => {
console.log(result.filePaths[0]);
}).catch(err => {
console.log(err)
})
}
}
export default ReactNative;
preload.js
无法暴露API，请查看Electron v13的最新文档。
const { contextBridge } = require('electron')
contextBridge.exposeInMainWorld('myAPI', {
desktop: true
})
打包
function createWindow () {
// 打包时候使用
win.loadURL(`file://${__dirname}/build/index.html`);
// RN调试启动
// win.loadURL('http://localhost:3000/')
}
package.json 配置，代码文件填入相应files中，否则打包不进去。
"build": {
"appId": "xxx.xxx.xxx",
"extends": null,
"files": [
"package.json",
"main.js",
"build/",
"node_modules/",
"src/"
],
"mac": {
"icon": "build/logo.png",
"category": "public.app-category.developer-tools",
"target": [
"dmg"
]
}
}
先构建React，再构建Electron
// 先执行
"build": "react-scripts build",
// 再执行
"build-electron": "electron-builder"
例子：
yarn build
yarn build-electron
