# Stitch to uni-app + uView 2.0 Components

**Constraint**: Only use this skill when the user explicitly mentions "Stitch" and converting Stitch screens to **uni-app + Vue 2 + uView 2.0** (pages/, components/, .vue, u-* components).

You are a **frontend engineer** turning Stitch designs into clean, modular uni-app + uView 2 code. Use Stitch MCP (or **stitch-mcp-get-screen**) to retrieve screen metadata and HTML; use scripts and resources in this skill for reliable fetch and quality checks.

## Prerequisites

- Stitch MCP Server (https://stitch.withgoogle.com/docs/mcp/guide/)
- uni-app / HBuilderX or Vue CLI for uni-app (Vue 2)
- Stitch project and screen IDs — **two ways**: (1) From a **Stitch design URL**: parse **projectId** (path) and **screenId** (`node-id` query). (2) When no URL or when browsing: use **stitch-mcp-list-projects** and **stitch-mcp-list-screens** to discover and obtain IDs.

## Official Documentation

- **uView 2.0 (Vue 2)**: [Official](https://www.uviewui.com/) · [Guide / Demo](https://www.uviewui.com/guide/demo.html) · [Components](https://www.uviewui.com/components/intro.html) · [GitHub](https://github.com/umicro/uView2.0)
- Full links and usage: [references/official.md](references/official.md)

## Retrieval and Networking

1. **Discover Stitch MCP prefix**: Run `list_tools` to find the prefix (e.g. `mcp_stitch__stitch:`).
2. **Fetch screen metadata**: Call `[prefix]:get_screen` with `projectId` and `screenId` (numeric IDs) to get design JSON, `htmlCode.downloadUrl`, `screenshot.downloadUrl`, dimensions, deviceType.
3. **High-reliability HTML download**: AI fetch tools can fail on Google Cloud Storage URLs. Use Bash to run the skill script:
   ```bash
   bash scripts/fetch-stitch.sh "<htmlCode.downloadUrl>" "temp/source.html"
   ```
   Ensure the URL is quoted.
4. **Visual reference**: Use `screenshot.downloadUrl` to confirm layout and details.

## Architectural Rules

- **Modular pages/components**: Split the design into pages under `pages/` and shared components under `components/`; avoid one giant page.
- **Logic isolation**: Put event handlers and mixins/utils in appropriate modules.
- **Data decoupling**: Move static text, image URLs, and lists into `data/` or page data.
- **uView 2 only (use framework components when available)**: Use `u-*` components per [references/contract.md](references/contract.md). Card-like blocks → **u-cell-group** + **u-cell** or **u-text**; hints/tips → **u-text**; dividers → **u-line** / **u-divider**. Do not use view/text + custom class (.card, .card-title, .label-optional, .tips-text, .unit).
- **Project-specific**: Omit third-party license headers from generated pages/components.

## Execution Steps

1. **Environment**: Ensure uni-app project has uView 2 installed and configured (main.js, uni.scss).
2. **Data layer**: Create or update data sources (e.g. `data/mockData.js`) from the design content.
3. **Page drafting**: Use `resources/page-template.vue` as base; replace placeholder with real page name and uView 2 tags per contract.
4. **Wiring**: Register pages in `pages.json`; add tabBar or navigation as needed.
5. **Quality check**: Verify against `resources/architecture-checklist.md`; run in HBuilderX or CLI to confirm on simulator/device.

## Integration with This Repo

- **Get screen**: Use **stitch-mcp-get-screen** with projectId and screenId. Obtain IDs either by parsing a **Stitch design URL** or by using **stitch-mcp-list-projects** and **stitch-mcp-list-screens** when no URL or when the user needs to browse/select.
- **Design spec**: If Stitch was generated with **stitch-ui-design-spec-uview** constraints, map to uni-app pages and uView 2 components. If converting from Stitch HTML (e.g. get_screen htmlCode), use [references/tailwind-to-uview.md](references/tailwind-to-uview.md) for Tailwind utility → rpx/theme, then [references/contract.md](references/contract.md) for component API.
- **Design system**: If the project has DESIGN.md (from **stitch-design-md**), align colors and spacing with that system when mapping to uView tokens.

## Troubleshooting

- **Fetch errors**: Quote the URL in the bash command; ensure `scripts/fetch-stitch.sh` is executable.
- **Component mapping**: Follow [references/contract.md](references/contract.md) for layout (u-row, u-col), forms (u-form, u-input), nav (u-navbar, u-tabs), list (u-swipe-action), feedback (u-toast, u-modal).

## Example: Stitch HTML to uView 2 Page

Stitch HTML with Tailwind card and button:
```html
<div class="bg-white rounded-lg shadow p-4"><h2 class="text-lg font-bold">Profile</h2><button class="bg-blue-500 text-white px-4 py-2 rounded">Save</button></div>
```

Converted uView 2 page:
```vue
<template>
  <view class="page">
    <u-navbar title="Profile" :autoBack="true" />
    <u-cell-group>
      <u-cell title="Profile" />
    </u-cell-group>
    <u-button type="primary" text="Save" @click="handleSave" />
  </view>
</template>
```

Key mapping: `div.rounded-lg.shadow` becomes `<u-cell-group>`, raw `<button>` becomes `<u-button type="primary">`, Tailwind px maps to rpx.
