前端小白安装node、vue、Express、Electron及(Electron桌面端exe应用开发)

一、node.js

（一）、下载

下载地址

Node.js — 在任何地方运行 JavaScript (nodejs.org)

参考文章：Node.js安装及环境配置超详细教程【Windows系统】_windows 安装nodejs-CSDN博客

（二）、安装

安装路径可以更换，其他都是默认下一步。

第一步增加系统变量

（1）新建变量NODE_HOME，变量值为安装路径：E:\Program Files\nodejs

（2） PATH 变量增加,需要先新建node_global和node_cache在E:\Program Files\nodejs路径下面。

%NODE_HOME%

%NODE_HOME%\node_global

%NODE_HOME%\node_cache

第二步增加用户变量

E:\Program Files\nodejs\node_global

检查安装情况

node -v

npm - v

C:\Windows\system32>npm -v
10.8.1C:\Windows\system32>node -v
v20.16.0

配置缓存目录和全局目录

缓存目录

npm config set cache “E:\Program Files\nodejs\node_cache”

全局目录**

npm config set prefix “E:\Program Files\nodejs\node_global”

(参考文档这边不对的)

设置成功可以看到，这边是我自己的路径
```
C:\Windows\system32>npm config get prefix
D:\it\node20\node_globalC:\Windows\system32>npm config get cache
D:\it\node20\node_cache
```
设置国内源配置（参考文档的镜像源已经不可用）

# 设置国内源
npm config set registry https://registry.npmmirror.com
# 查看国内源
npm get registry

如果不行在换一个

npm config set registry http://registry.npmjs.org/

删除npm config delete registry

使用pnmp方式安装

第一步设置国内源：npm config set registry https://registry.npmmirror.com (我是这个镜像可以安装pnmp)

第二步安装pnmp: npm install pnpm -g

二、Express

express使用

存储变量需要配置好不然会报错的

D:\it\node20\node_cache\node_modules>express --version
‘express’ 不是内部或外部命令，也不是可运行的程序

安装方式(需要使用管理员权限)

npm install express -g

npm install express-generator -g

移除是

npm uninstall express -g

npm uninstall express-generator -g

部分资料没有这个 express-generator 是没有办法使用的，

你将无法使用 express 命令来创建新的 Express 应用，因为 express 命令实际上是 express-generator 提供的。
安装成功

D:\it\node20\node_cache\node_modules>express --version
4.16.1

express启动

express express_example
destination is not empty, continue? [y/N] y
cd express_example
npm install
# windows 命令行
set DEBUG=myapp:* & npm start

express-example@0.0.0 start
> node ./bin/wwwGET / 200 1734.181 ms - 170
GET /stylesheets/style.css 200 3.004 ms - 111
GET /favicon.ico 404 8.515 ms - 1172

成功后浏览器打开 http://localhost:3000/ ，一个应用就启动了。还是很方便的。

参考：Express 应用程序生成器 - Express中文文档 | Express中文网 (expressjs.com.cn)

5. express 关闭

Ctrl + C

终止批处理操作吗(Y/N)? Y

三、vue.js

(一)、vue安装

npm install vue -g

npm install vue-cli -g

D:\it>vue -V
2.9.6

四、Electron记事板开发

(一)、初始化项目

创建一个新的项目目录并初始化

mkdir electron-notepad
cd electron-notepad
npm init -y

(二)、安装Electron

安装Electron作为项目的依赖,时间很长。我花了10多分钟。

pnpm install electron --save-dev

成功输出

Packages: +75
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Progress: resolved 75, reused 0, downloaded 75, added 75, done
node_modules/.pnpm/electron@31.3.1/node_modules/electron: Running postinstall script, done in 10m 19.2sdevDependencies:
+ electron 31.3.1

(三)、创建主进程文件

在项目根目录下创建main.js

const { app, BrowserWindow } = require('electron');function createWindow () {// 创建浏览器窗口let win = new BrowserWindow({width: 800,height: 600,webPreferences: {nodeIntegration: true}});// 加载index.html文件win.loadFile('index.html');
}app.on('ready', createWindow);

在项目根目录下创建index.html，这将是记事本的界面

<!DOCTYPE html>
<html>
<head><title>Electron Notepad</title>
</head>
<body><textarea id="notepad" style="width: 100%; height: 90%;"></textarea><br><button onclick="save()">保存</button><button onclick="load()">打开</button><script>const { ipcRenderer } = require('electron');function save() {let text = document.getElementById('notepad').value;ipcRenderer.send('save-text', text);}function load() {ipcRenderer.send('load-text');}ipcRenderer.on('received-text', (event, text) => {document.getElementById('notepad').value = text;});</script>
</body>
</html>

在main.js中添加IPC通信，以便在Electron的主进程和渲染进程之间传递数据

const { ipcMain } = require('electron');ipcMain.on('save-text', (event, text) => {// 这里可以添加保存文件的逻辑console.log('Text saved:', text);
});ipcMain.on('load-text', (event) => {// 这里可以添加加载文件的逻辑event.reply('received-text', 'This is loaded text.');
});

(四)、编译安装包

安装electron-builder

pnpm install electron-builder --save-dev

在package.json中添加构建脚本

"scripts": {"start": "electron .","dist": "electron-builder"
}

main改为main.js

"main": "main.js",

运行构建命令

Windows :pnpm run dist --win

macos:pnpm run dist --mac

Linux:pnpm run dist --linux

失败了，如果github访问没有问题不会存在以下错误。(成功不需要看)

手动下载

迅雷下载

https://github.com/electron/electron/releases/download/v31.3.1/electron-v31.3.1-win32-x64.zip

下载后放到electron-notepad\node_modules\electron 目录下解压electron-v31.3.1-win32-x64.zip。

electron-notepad\node_modules\electron 目录下创建path.txt文件，增加文件内容为electron.exe。

重写执行pnpm run dist --win

成功的输出
