项目架构与技术栈分析
ContiNew Admin UI基于现代化的前端技术栈构建,采用Vue 3、TypeScript、Vite和Arco Design等前沿技术。让我们先深入了解项目的技术特性:
核心依赖分析
通过package.json分析,项目的主要生产依赖包括:
| 依赖类别 | 关键技术 | 版本 | 用途 |
|---|---|---|---|
| 前端框架 | Vue 3 | 3.5.4 | 核心框架 |
| 构建工具 | Vite | 5.1.5 | 构建和开发服务器 |

Docker镜像构建最佳实践
多阶段构建策略
为了优化镜像体积和安全性,我们采用多阶段构建策略:
# 第一阶段:构建阶段
FROM node:18-alpine AS builder
# 设置工作目录
WORKDIR /app
# 复制package文件
COPY package.json pnpm-lock.yaml ./
# 安装pnpm
RUN npm install -g pnpm@8
# 安装依赖
RUN pnpm install --frozen-lockfile
# 复制源代码
COPY . .
# 构建项目
RUN pnpm run build
# 第二阶段:生产阶段
FROM nginx:alpine AS production
# 复制构建产物
COPY --from=builder /app/dist /usr/share/nginx/html
# 复制nginx配置
COPY nginx.conf /etc/nginx/conf.d/default.conf
# 暴露端口
EXPOSE 80
# 启动nginx
CMD ["nginx", "-g", "daemon off;"]
优化构建配置
在vite.config.ts中,我们已经配置了优化的构建选项:
// vite.config.ts 构建配置
build: {
chunkSizeWarningLimit: 2000,
outDir: 'dist',
minify: 'terser',
terserOptions: {
compress: {
keep_infinity: true,
drop_console: true,
drop_debugger: true,
},
format: {
comments: false,
},
},
rollupOptions: {
output: {
chunkFileNames: 'static/js/[name]-[hash].js',
entryFileNames: 'static/js/[name]-[hash].js',
assetFileNames: 'static/[ext]/[name]-[hash].[ext]',
},
},
}
Nginx配置优化
创建优化的nginx配置文件:
# nginx.conf
server {
listen 80;
server_name localhost;
# 根目录配置
root /usr/share/nginx/html;
index index.html;
# Gzip压缩
gzip on;
gzip_vary on;
gzip_min_length 1024;
gzip_types text/plain text/css text/xml text/javascript application/javascript application/xml+rss application/json;
# 静态资源缓存
location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff2)$ {
expires 1y;
add_header Cache-Control "public, immutable";
}
# HTML文件不缓存
location ~* \.(html)$ {
expires -1;
add_header Cache-Control "no-store";
}
# SPA路由支持
location / {
try_files $uri $uri/ /index.html;
}
# 健康检查端点
location /health {
access_log off;
return 200 "healthy\n";
add_header Content-Type text/plain;
}
}
