Core Workflow

核心工作流程

  1. Analyze requirements → Identify static vs dynamic content, hydration needs, data sources
  2. Design structure → Plan pages, layouts, components, content collections
  3. Implement components → Create Astro components with proper client directives
  4. Configure routing → Set up file-based routing, dynamic routes, endpoints
  5. Optimize delivery → Configure adapters, image optimization, view transitions
  1. 需求分析 → 区分静态与动态内容、水合需求、数据源
  2. 结构设计 → 规划页面、布局、组件、内容集合
  3. 组件实现 → 创建带有正确客户端指令的Astro组件
  4. 路由配置 → 设置基于文件的路由、动态路由、端点
  5. 交付优化 → 配置适配器、图片优化、视图过渡

Critical Rules

关键规则

MUST DO

必须遵守

  • Use islands architecture—only hydrate interactive components
  • Choose appropriate client directives based on interaction needs
  • Define content collection schemas with Zod for type safety
  • Use 
    <Image />
    and 
    <Picture />
    for optimized images
  • Implement proper error boundaries for client components
  • Use TypeScript with strict mode for type safety
  • Configure appropriate adapter for deployment target
  • Use 
    Astro.props
    for component data passing
  • 使用孤岛架构——仅对交互式组件进行水合
  • 根据交互需求选择合适的客户端指令
  • 使用Zod定义内容集合模式以确保类型安全
  • 使用
    <Image />
    和
    <Picture />
    进行图片优化
  • 为客户端组件实现适当的错误边界
  • 使用严格模式的TypeScript以确保类型安全
  • 为部署目标配置合适的适配器
  • 使用
    Astro.props
    传递组件数据

MUST NOT DO

禁止操作

  • Hydrate components that don't need interactivity (use 
    client:
    only when necessary)
  • Use 
    client:only
    without specifying the framework
  • Import images with string paths (use import statements)
  • Skip schema validation in content collections
  • Mix 
    server
    and 
    hybrid
    output modes incorrectly
  • Access 
    Astro.request
    in prerendered pages
  • Use browser APIs in component frontmatter (server-side code)
  • Forget to install adapters for SSR deployment
  • 对不需要交互的组件进行水合（仅在必要时使用
    client:
    指令）
  • 使用
    client:only
    时不指定框架
  • 使用字符串路径导入图片（请使用import语句）
  • 跳过内容集合中的模式验证
  • 错误混合
    server
    和
    hybrid
    输出模式
  • 在预渲染页面中访问
    Astro.request
  • 在组件前置脚本（服务器端代码）中使用浏览器API
  • 部署SSR时忘记安装适配器

Quick Reference

Component Structure

组件结构

astro
---
// Component Script (runs on server)
interface Props {
  title: string;
  count?: number;
}
const { title, count = 0 } = Astro.props;
const data = await fetch('https://api.example.com/data');
---

<!-- Component Template -->
<div>
  <h1>{title}</h1>
  <p>Count: {count}</p>
</div>

<style>
  /* Scoped by default */
  h1 { color: navy; }
</style>
astro
---
// Component Script (runs on server)
interface Props {
  title: string;
  count?: number;
}
const { title, count = 0 } = Astro.props;
const data = await fetch('https://api.example.com/data');
---

<!-- Component Template -->
<div>
  <h1>{title}</h1>
  <p>Count: {count}</p>
</div>

<style>
  /* Scoped by default */
  h1 { color: navy; }
</style>

Client Directive Priority

客户端指令优先级

  1. No directive → Static HTML, zero JavaScript
  2. client:load
     → Hydrate immediately on page load
  3. client:idle
     → Hydrate when browser is idle
  4. client:visible
     → Hydrate when component enters viewport
  5. client:media
     → Hydrate when media query matches
  6. client:only
     → Skip SSR, render only on client
  1. 无指令 → 静态HTML，无JavaScript
  2. client:load
     → 页面加载时立即水合
  3. client:idle
     → 浏览器空闲时水合
  4. client:visible
     → 组件进入视口时水合
  5. client:media
     → 媒体查询匹配时水合
  6. client:only
     → 跳过SSR，仅在客户端渲染

Content Collection Schema

内容集合模式

typescript
// src/content/config.ts
import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
  type: 'content',
  schema: z.object({
    title: z.string(),
    date: z.date(),
    draft: z.boolean().default(false),
    tags: z.array(z.string()).optional(),
  }),
});

export const collections = { blog };
typescript
// src/content/config.ts
import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
  type: 'content',
  schema: z.object({
    title: z.string(),
    date: z.date(),
    draft: z.boolean().default(false),
    tags: z.array(z.string()).optional(),
  }),
});

export const collections = { blog };
