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
