需要提前了解的知识
- Angular官网
- Angular CLI
- Electron
- socket.io
使用Angular CLI创建项目
首先全局安装Angular CLI
npm install -g @angular/cli创建项目
ng new my-app一个完整的Angular项目就大功告成了
集成Electron
首先本地安装Electron
npm install electron --save-dev在根目录下的package.json中声明项目入口文件
"main": "main.js",然后scripts对象添加新的脚本
"preelectron": "npm run build",
"electron": "electron .",preelectron表示预执行脚本，表示npm在每次执行electron前会自动先执行改脚本。
下面在项目的根目录下添加electron入口文件main.js
const electron = require('electron')
// Module to control application life.
const app = electron.app
// Module to create native browser window.
const BrowserWindow = electron.BrowserWindow
const path = require('path')
const url = require('url')
// 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})
// and load the index.html of the app.
mainWindow.loadURL(url.format({
pathname: path.join(__dirname, 'dist/index.html'),
protocol: 'file:',
slashes: true
}))
// 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 OS X 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 OS X 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.
注意我们把index.html的载入路径改为了dist/index.html, 因为使用Angular CLI生成的项目会自动集成webpack，在项目运行在开发模式下时会自动启动webpack， 此时eletron无法访问index.html，所以只有在生产模式下生成打包压缩后的文件才能直接被electron访问到。
