# FlowGram 文档的组织结构

- **英文文档**: `apps/docs/src/en`
- **中文文档**: `apps/docs/src/zh`
- **Story 组件**: `apps/docs/components/form-materials/components`
- **物料源码**: `packages/materials/form-materials/src/components`
- **文档模板**: `./templates/material.mdx`

# 组件物料文档撰写流程

## 1. 源码定位

在 `packages/materials/form-materials/src/components` 目录下确认物料源代码地址。

**操作**:
- 使用 Glob 工具搜索物料文件
- 确认目录结构(是否有 hooks.ts, context.tsx 等)
- 记录导出名称和文件路径

## 2. 需求收集

向用户询问物料使用实例和具体需求。

**收集信息**:
- 主要使用场景
- 典型代码示例(1-2 个)
- 特殊配置或高级用法
- 是否需要配图

## 3. 功能分析

深入阅读源代码,理解物料功能。

**分析要点**:
- Props 接口(类型、默认值、描述)
- 核心功能和实现方式
- 依赖关系(FlowGram API、其他物料、第三方库)
- Hooks 和 Context
- 特殊逻辑(条件渲染、副作用等)

## 4. Story 创建

在 `apps/docs/components/form-materials/components` 下创建 Story 组件(详见下方 Story 规范)。

## 5. 文档撰写

基于模板 `./templates/material.mdx` 撰写完整文档。

**文档位置**:
- 中文:`apps/docs/src/zh/materials/components/{物料名称}.mdx`
- 英文:`apps/docs/src/en/materials/components/{物料名称}.mdx`(翻译后)

## 6. 质量检查

**检查清单**:
- [ ] Story 组件能正常运行
- [ ] 代码示例准确无误
- [ ] API 表格完整
- [ ] 依赖链接正确可访问
- [ ] 图片路径正确
- [ ] Mermaid 流程图语法正确
- [ ] CLI 命令路径准确

**用户确认中文文档的撰写后,再执行翻译**。

# Story 组件规范

> **参考示例**: `apps/docs/components/form-materials/components/variable-selector.tsx`

## 命名规范

**文件命名**: kebab-case,与物料名称一致
- ✅ `variable-selector.tsx`
- ✅ `dynamic-value-input.tsx`
- ❌ `VariableSelector.tsx`

**Story 导出命名**: PascalCase + "Story" 后缀
- `BasicStory` - 基础使用(必需)
- `WithSchemaStory` - 带 Schema 约束
- `DisabledStory` - 禁用状态
- `CustomFilterStory` - 自定义过滤
- 根据物料特性命名,见名知意

## 代码要求

### 1. 懒加载导入

```tsx
// ✅ 正确
const VariableSelector = React.lazy(() =>
  import('@flowgram.ai/form-materials').then((module) => ({
    default: module.VariableSelector,
  }))
);

// ❌ 错误
import { VariableSelector } from '@flowgram.ai/form-materials';
```

### 2. 包装组件

```tsx
// ✅ 正确
export const BasicStory = () => (
  <FreeFormMetaStoryBuilder
    filterEndNode
    formMeta={{
      render: () => (
        <>
          <FormHeader />
          <Field<string[]> name="variable_selector">
            {({ field }) => (
              <VariableSelector
                value={field.value}
                onChange={(value) => field.onChange(value)}
              />
            )}
          </Field>
        </>
      ),
    }}
  />
);

// ❌ 错误:缺少包装
export const BasicStory = () => (
  <VariableSelector value={[]} onChange={() => {}} />
);
```

### 3. 类型标注

```tsx
// ✅ 正确
<Field<string[] | undefined> name="variable_selector">

// ❌ 错误
<Field<any> name="variable_selector">
```

### 4. 语言规范

代码和注释只使用英文,无中文。

## 完整示例

```tsx
/**

 */

import React from 'react';
import { Field } from '@flowgram.ai/free-layout-editor';
import { FreeFormMetaStoryBuilder, FormHeader } from '../../free-form-meta-story-builder';

const VariableSelector = React.lazy(() =>
  import('@flowgram.ai/form-materials').then((module) => ({
    default: module.VariableSelector,
  }))
);

export const BasicStory = () => (
  <FreeFormMetaStoryBuilder
    filterEndNode
    formMeta={{
      render: () => (
        <>
          <FormHeader />
          <Field<string[] | undefined> name="variable_selector">
            {({ field }) => (
              <VariableSelector
                value={field.value}
                onChange={(value) => field.onChange(value)}
              />
            )}
          </Field>
        </>
      ),
    }}
  />
);

export const FilterSchemaStory = () => (
  <FreeFormMetaStoryBuilder
    filterEndNode
    formMeta={{
      render: () => (
        <>
          <FormHeader />
          <Field<string[] | undefined> name="variable_selector">
            {({ field }) => (
              <VariableSelector
                value={field.value}
                onChange={(value) => field.onChange(value)}
                includeSchema={{ type: 'string' }}
              />
            )}
          </Field>
        </>
      ),
    }}
  />
);
```

# 物料文档格式

## 使用模板

**模板文件**: `./templates/material.mdx`

文档必须严格按照模板格式编写,包含以下章节:
1. Import 语句
2. 标题和简介(带可选配图)
3. 案例演示(基本使用 + 高级用法)
4. API 参考(Props 表格)
5. 源码导读(目录结构、核心实现、流程图、依赖梳理)

## 参考示例

- [`dynamic-value-input.mdx`](apps/docs/src/zh/materials/components/dynamic-value-input.mdx) - 完整的流程图和依赖说明
- [`variable-selector.mdx`](apps/docs/src/zh/materials/components/variable-selector.mdx) - 多个 API 表格和警告提示

## 关键注意事项

**API 表格要求**:
- 必须包含所有公开的 Props
- 类型使用反引号(如 \`string\`)
- 描述清晰简洁
- 多个相关类型分开列表

**源码导读要求**:
- 目录结构:展示文件列表及说明
- 核心实现:用代码片段说明关键逻辑
- 整体流程:Mermaid 流程图(推荐)
- 依赖梳理:分类列出 FlowGram API、其他物料、第三方库

# 图片处理指南

## 截图要求

1. **时机**: Story 组件完成后,运行 docs 站点截图
2. **内容**: 捕获物料的典型使用状态,清晰可见
3. **格式**: PNG,适当压缩

## 命名和存储

- **命名**: `{物料名称}.png`(kebab-case)
- **存储**: `apps/docs/src/public/materials/{物料名称}.png`
- **引用**: `/materials/{物料名称}.png`

## 在文档中使用

```mdx
<br />
<div>
  <img loading="lazy" src="/materials/{物料名称}.png" alt="{物料名称} 组件" style={{ width: '50%' }} />
</div>
```

# 翻译流程

## 翻译时机

- ✅ 用户明确要求翻译
- ✅ 中文文档已经用户审核确认
- ❌ 文档还在修改中
- ❌ 用户未确认最终版本

## 翻译原则

**术语一致性**:
- ComponentName → ComponentName(组件名不翻译)
- Props、Hook、Schema 等术语保持原文

**代码不翻译**:
- 所有代码块、命令、路径保持原样

**链接处理**:
- 内部链接:`/zh/` → `/en/`
- 外部链接和 GitHub 链接:保持不变

**格式保持**:
- Markdown 格式、缩进、空行完全一致

## 翻译检查清单

- [ ] 标题和描述已翻译
- [ ] 代码示例未被翻译
- [ ] 命令和路径保持原样
- [ ] 内部文档链接已更新
- [ ] API 表格描述列已翻译
- [ ] Mermaid 图中文节点已翻译
- [ ] 术语使用一致

# 最佳实践

## Props 提取技巧

1. 查找 `interface` 或 `type` 定义
2. 检查组件函数参数类型
3. 查找 `defaultProps` 确认默认值
4. 阅读 JSDoc 提取描述

## 依赖分析方法

1. 查看 import 语句(直接依赖)
2. 分析 Hook 调用(FlowGram API)
3. 查找组件引用(其他物料)
4. 检查 package.json(第三方库)

## Mermaid 流程图建议

1. 简洁明了,关注核心流程
2. 使用时序图绘制

## 常见错误避免

❌ 直接导入物料而不使用 `React.lazy`
❌ API 表格遗漏 Props
❌ 依赖链接失效
❌ 中英文混用
❌ 路径格式错误

✅ 参考优秀示例
✅ 仔细阅读源码
✅ 验证所有链接
✅ 保持语言和格式一致
✅ 使用项目约定的路径格式

Overview

This skill streamlines writing FlowGram material component documentation, Story creation, screenshot handling, and translation guidance. It packages a repeatable workflow for locating source code, extracting props, authoring MDX docs from a template, and producing Story components that run in the docs site. The skill emphasizes consistency, correctness, and readiness for translation after user sign-off.

How this skill works

The skill inspects the materials source folder to locate component files and type definitions, then extracts Props, default values, and dependency imports. It scaffolds Story components using lazy imports and the required story wrapper, generates a markdown MDX document following the material template, and produces a checklist for QA and translation. It can also suggest screenshot capture instructions and file placement for docs assets.

When to use it

  • Creating a new material component documentation page and Story for the docs site
  • Updating documentation after component API changes or refactors
  • Preparing a component for translation once Chinese docs are approved
  • Performing a quality check before publishing docs or merging PRs
  • Automating Prop extraction and API table generation from TypeScript types

Best practices

  • Always lazy-load components in Stories using React.lazy with explicit default export mapping
  • Wrap component demos in the provided FreeFormMetaStoryBuilder or equivalent story wrapper
  • Extract Props from TypeScript interfaces/types and include default values and concise descriptions
  • Keep code and comments fully English in Stories and docs source
  • Only translate after the user confirms the final Chinese doc; keep code and paths unchanged during translation

Example use cases

  • Generate a complete MDX doc for a new form material component with basic and advanced examples
  • Create Story files (kebab-case) with BasicStory, WithSchemaStory, and DisabledStory exports
  • Produce an API Props table by parsing TypeScript interfaces and defaultProps
  • Provide a step-by-step checklist and mermaid flow suggestions for the source walkthrough section
  • Prepare image assets: capture Story UI, save PNG in the public materials folder, and reference it in MDX

FAQ

When should I run translation?

Run translation only after the Chinese documentation has been reviewed and confirmed by the user; this prevents repeated translation work during edits.

How must Stories import components?

Always use React.lazy with a then mapping to set the default export instead of static imports to follow docs bundling expectations.
