一、工程架构设计
1.1 现代化项目初始化
采用多包管理架构：
mkdir content-platform && cd content-platform
npm init -y
npx lerna init
mkdir -p {packages/client,packages/server,packages/shared}关键模块划分：
-
client/: 基于Next.js的SSR前端
-
server/: NestJS RESTful API服务
-
shared/: 通用类型定义与工具库
1.2 依赖管理优化
.npmrc生产级配置：
# 提升依赖安装效率
prefer-offline=true
legacy-peer-deps=true
# 安全策略
ignore-scripts=true
engine-strict=true二、前端工程化实践
2.1 动态内容加载
实现按需内容渲染：
// packages/client/components/ContentLoader.tsx
const ContentBlock = dynamic(
() => import('@shared/ui').then(mod => mod.ContentBlock),
{
loading: () => <Skeleton active />,
ssr: false
}
)2.2 构建性能优化
next.config.js高级配置：
module.exports = {
experimental: {
swcMinify: true,
esmExternals: 'loose',
outputFileTracingRoot: path.join(__dirname, '../../')
},
compiler: {
styledComponents: {
displayName: process.env.NODE_ENV === 'development'
}
}
}三、后端服务深度开发
3.1 数据库集成
TypeORM生产配置：
// packages/server/src/data-source.ts
export const AppDataSource = new DataSource({
type: 'postgres',
poolSize: 20,
synchronize: false,
logging: ['error'],
entities: [/*...*/],
extra: {
ssl: {
rejectUnauthorized: false,
ca: process.env.DB_CA_CERT
}
}
})3.2 高性能缓存
Redis集群集成：
// packages/server/libs/cache.ts
const redis = new Redis.Cluster([
{ host: 'redis-node1', port: 6379 },
{ host: 'redis-node2', port: 6380 }
], {
enableReadyCheck: true,
scaleReads: 'slave',
slotsRefreshTimeout: 5000
})四、前后端协同开发
4.1 API契约管理
使用OpenAPI规范：
# packages/shared/spec/content-api.yaml
paths:
/api/v1/content:
get:
parameters:
- $ref: '#/components/parameters/pageSize'
responses:
200:
content:
application/json:
schema:
$ref: '#/components/schemas/ContentList'4.2 联调优化方案
开发环境代理配置：
// packages/client/proxy.conf.js
module.exports = {
'/api': {
target: 'http://localhost:3001',
changeOrigin: true,
pathRewrite: { '^/api': '' },
onProxyReq: (proxyReq) => {
proxyReq.setHeader('X-Node-Env', process.env.NODE_ENV)
}
}
}五、部署与监控
5.1 容器化部署
Docker多阶段构建：
# 前端构建阶段
FROM node:18-bullseye AS client-builder
WORKDIR /build
COPY packages/client .
RUN npm ci --prefer-offline && npm run build
# 生产镜像
FROM node:18-alpine
COPY --from=client-builder /build/.next /app/.next
COPY packages/server /app
CMD ["node", "/app/server.js"]5.2 性能监控
APM集成方案：
// packages/server/src/main.ts
import * as apm from 'elastic-apm-node'
apm.start({
serviceName: 'content-api',
secretToken: process.env.APM_TOKEN,
serverUrl: process.env.APM_SERVER
})
