Electron初识
安装：
-
- 依赖nodejs
$ sudo apt install nodejs $ sudo apt install npm
- 安装electron
$ npm install --save-dev electron
- 依赖nodejs
HelloWorld：
npm init 初始化项目请参考其他文章
mkdir my-electron-app && cd my-electron-app npm init
package.json大致如下：
{
"name": "my-electron-app",
"version": "1.0.0",
"description": "Hello World!",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "electron ."
},
"author": "lizy",
"license": "ISC",
"devDependencies": {
"@electron-forge/cli": "^6.0.0-beta.59",
"electron": "^13.1.7"
}
}
示例代码：
// main.js
// Modules to control application life and create native browser window
const { app, BrowserWindow } = require('electron')
const path = require('path')
function createWindow () {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
// and load the index.html of the app.
mainWindow.loadFile('index.html')
// Open the DevTools.
// mainWindow.webContents.openDevTools()
}
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// 部分 API 在 ready 事件触发后才能使用。
app.whenReady().then(() => {
createWindow()
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 (BrowserWindow.getAllWindows().length === 0) createWindow()
})
})
// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', function () {
if (process.platform !== 'darwin') app.quit()
})
// In this file you can include the rest of your app's specific main process
// code. 也可以拆分成几个文件，然后用 require 导入。
// preload.js
// All of the Node.js APIs are available in the preload process.
// It has the same sandbox as a Chrome extension.
window.addEventListener('DOMContentLoaded', () => {
const replaceText = (selector, text) => {
const element = document.getElementById(selector)
if (element) element.innerText = text
}
for (const dependency of ['chrome', 'node', 'electron']) {
replaceText(`${dependency}-version`, process.versions[dependency])
}
})

打包分发
- 安装electron-forge
npm install --save-dev @electron-forge/cli npx electron-forge import
- 打包
npm run make
问题：
-
- 升级node.js
sudo npm install -g n sudo n stable # latest #(升级node.js到最新版) stable #（升级node.js到最新稳定版） node -v npm -v
- 打包报错
Error: Cannot make for rpm, the following external binaries need to be installed: rpmbuildsudo apt install rpm
- 替换npm镜像为淘宝镜像
#得到原本的镜像地址 npm get registry #设成淘宝的 npm config set registry http://registry.npm.taobao.org/ #换成原来的 npm config set registry https://registry.npmjs.org/
- 升级node.js
