electron开发

安装NodeJS

目前支持的最新版本为NodeJS 7.4.0，因为安装过程比较简单所以这里省略了。

安装Electron

npm install -g electron

创建项目工程

使用WebStorm创建一个Empty Project.

用npm init初始化这个项目。初始化后，package.json内容如下

{
  "name": "facerecognition_test",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron .",
    "pack": "electron-packager --electron-version=16.11 .",
    "build": "build "
  },

  "author": "Chen Haifeng",
  "license": "ISC"
}

添加文件index.html

    
    


调用人脸识别DLL

添加文件main.js

const {app, BrowserWindow} = require('electron')
const path = require('path')
const url = require('url')
//import url from "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 win

function createWindow () {
    console.log('createWindow')

    // Create the browser window.
    win = new BrowserWindow({width: 800, height: 600})

    // and load the index.html of the app.
    win.loadURL(url.format({
        pathname: path.join(__dirname, 'index.html'),
        protocol: 'file:',
        slashes: true
    }))

    // Open the DevTools.
    win.webContents.openDevTools()

    // Emitted when the window is closed.
    win.on('closed', () => {
        // 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.
        win = 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', () => {
    // 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', () => {
    // 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 (win === null) {
        console.log('activate')
        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.

测试项目

如果electron是采用全局安装的，使用electron .来运行项目。

如果electron是安装在项目的node_modules目录，使用.\node_modules\.bin\electron .来运行项目。

因为在package.json文件中做了配置，所以这里可以使用npm start运行项目。

打包项目

安装electron-packager

npm install -g electron-packager

electron-packager --electron-version=1.6.11 .

生成结果如下

运行一下打包后的exe程序

制作平台安装包

npm install -g electron-builder

执行命令build， 整个过程比较漫长。 

自动更新下次补充。
