uniapp打包桌面应用

uniapp项目打包为桌面应用

一、在项目根目录下安装electron,这里建议使用cnpm，否则会很慢

cnpm install electron --save-dev

二、在项目根目录下安装electron-packager（打包用）

cnpm install electron-packager -g

三、修改uniapp的manifest.json配置文件

1. 找到h5配置，将运行的基础路径改为./，否则打包出来后会白屏，读取不到，因为打包出来的h5默认加载地址为/static/

1. 去掉启用https协议前的√，否则会出现网络无法加载，去掉https不影响你请求后端的https协议

四、H5打包

1. HbuilderX顶部的菜单栏 --> 发行 --> 网站-h5手机版 --> 发行

1. 发行后的默认目录为：unpackage\dist\build\h5

五、新建配置文件

1. 发行后的目录新建package.json并添加以下内容

{
 "name"  : "app-name",
 "version" : "0.1.0",
 "main"  : "main.js"
}

1. 发行后的目录新建main.js并添加以下内容,本文件就是package.json文件中main键的值，可根据需求修改

const {app, BrowserWindow} = require('electron')
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 win

function 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) {
  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.

ps: 若是你的网页首页文件名不是index.html,那么请在main.js中将index.html修改为你的网页首页

六、打包

1. 使用cmd外置命令窗口进入H5打包后的目录unpackage\dist\build\h5运行以下命令

electron-packager . 可执行文件的文件名 --win --out 打包成的文件夹名 --arch=x64位还是32位 --electron-version版本号(不是你的h5版本号，是electron版本号) --overwrite --ignore=node_modules

1. 也可直接复制以下示例命令

electron-packager . MyApp --win --out MyApp --arch=x64 --electron-version 1.4.14 --overwrite --ignore=node_modules

1. 打包后本目录会出现MyApp目录，进入后找到.exe后缀文件打开后即可看到桌面应用

PS：当网页更新内容后再次使用h5发行前，记得备份package.json和main.js
