Electron——環境搭建
1. 安裝Electron
cnpm install electron --save-dev # 本地安裝Electron
npx electron -v # 檢查版本
2. 項目根目錄下新建main.js文件（程序入口）
// Modules to control application life and create native browser window
const {app, BrowserWindow} = require('electron')
// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow
function createWindow () {
// Create the browser window.
mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true
}
})
// and load the index.html of the app.
mainWindow.loadFile('index.html')
// Open the DevTools.
// mainWindow.webContents.openDevTools()
// Emitted when the window is closed.
mainWindow.on('closed', function () {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
mainWindow = null
})
}
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)
// Quit when all windows are closed.
app.on('window-all-closed', function () {
// On macOS it is common for applications and their menu bar
// to stay active until the user quits explicitly with Cmd + Q
if (process.platform !== 'darwin') app.quit()
})
app.on('activate', function () {
// On macOS it's common to re-create a window in the app when the
// dock icon is clicked and there are no other windows open.
if (mainWindow === null) createWindow()
})
// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
3. 項目根目錄下新建index.html文件 (主頁)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Hello World!</title>
</head>
<body>
Hello World!
</body>
</html>
4. 初始化環境
npm init --yes # 生成package.json文件
5. 在package.json文件中配置electron命令
"scripts": {
"start": "electron .",
}
6. 啓動程序
npm start
使用 VSCode 進行主進程調試
1.在 VSCode 中打開一個 Electron 項目。
$ git clone [email protected]:electron/electron-quick-start.git
$ code electron-quick-start
2.添加一個 .vscode/launch.json 文件並使用以下配置：
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Main Process",
"type": "node",
"request": "launch",
"cwd": "${workspaceFolder}",
"runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
"windows": {
"runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd"
},
"args" : ["."]
}
]
}
3. 調試
在 main.js中設置一些斷點，並在 Debug 視圖 中開始調試。你應該能夠捕獲斷點信息。
這是一個預先配置的項目，你可以下載並直接在 VSCode中調試: https://github.com/octref/vscode-electron-debug/tree/master/electron-quick-start
