electron 开发时最麻烦就是electron版本和node版本的选择和正确安装
electron 用npm安装时太慢容易报错,建议用cnpm i 进行安装
javascript
注意最新版渲染进程使用node
nodeIntegration: true, // 渲染进程可用node
contextIsolation: false, // 这个值影响nodeIntegration是否生效
electron 的主进程的创建
function createWindow () {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true, // 渲染进程可用node
contextIsolation: false, // 这个值影响nodeIntegration是否生效
preload: path.join(__dirname, 'preload.js')
}
})
// and load the index.html of the app.
mainWindow.loadFile(path.join(__dirname, 'index.html'))
// Open the DevTools.
mainWindow.webContents.openDevTools()
// 渲染进程使用remote
remote.enable(mainWindow.webContents)//3
require("./ipcMain/menu")
require("./ipcMain/rightMenu")
// 主进程发送消息
mainWindow.webContents.send("mainMag","发财发财")
}
app.on('ready', createWindow);
