Typescript开发React备注

开发前端谷歌浏览器插件思路

1. 使用 Typescript + React 开发页面

2. 使用node.js，构建本地服务器，完成网络请求转发，避免本地调试时出现跨域请求异常。

3. 使用 Nginx 部署本地服务器，模拟页面加载和跳转的完整流程。

4. 使用 webpack 处理模块依赖，合并 js 代码为单一 js 文件，生成 content-script.js background.js pop.js 等

 

基础准备

1. node.js + npm 安装 （或yarn等包管理工具）

brew install node

或者前往下载安装包

https://nodejs.org/zh-cn

2. react + typescript 安装

npm install -g typescript

npx create-react-app my-app --template typescript

3.创建代理服务项目

{
  "compilerOptions": {
    "target": "ES6",
    "module": "commonjs",
    "outDir": "./dist",
    "rootDir": "./src",
    "strict": true,
    "esModuleInterop": true
  },
  "include": ["src"],
  "exclude": ["node_modules"]
}

{
  "name": "proxy-server",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "cors": "^2.8.5",
    "express": "^4.19.2",
    "http-proxy-middleware": "^3.0.0"
  },
  "devDependencies": {
    "@types/express": "^4.17.21",
    "@types/node": "^20.14.10",
    "typescript": "^5.5.3"
  }
}

 

import express from 'express';
const cors = require('cors');
import { createProxyMiddleware } from 'http-proxy-middleware';

const app = express();

const corsOptions = {
    origin: 'http://localhost:8080', // 针对来源于该域名和端口的请求允许跨域
    optionsSuccessStatus: 200 // 一些老旧的浏览器会对204状态码进行错误处理
};

app.use(cors(corsOptions));

app.use('/api', createProxyMiddleware({
// http://localhost:3001/api/test 将转发到 https://xx.xx.app/test 
    target: 'https://xx.xx.app', // 转发的目标服务器地址
    changeOrigin: true,
    pathRewrite: {
        '^/api': '',
    },
}));

const PORT = 3001; // 本地服务端口号

app.listen(PORT, () => {
    console.log(`Proxy server is running on http://localhost:${PORT}`);
});

4. 安装和运行Nginx服务

brew install nginx

nginx -v //查看版本

nginx -t //查看配置文件地址

sudo nginx //启动

sudo nginx -s reload //重新加载配置文件

sudo nginx -s stop //停止

 

Nginx配置文件
