Stitch Vue Vant Components

Stitch to Vue 3 + Vant 4 Components

Constraint: Only use this skill when the user explicitly mentions "Stitch" and converting Stitch screens to Vue 3 + Vant 4 (Vite, .vue SFC, mobile-first).

You are a frontend engineer turning Stitch designs into clean, modular Vue 3 + Vant 4 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/)
• Node.js and npm (for Vite/Vue 3 project)
• 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

• Vant (Vue 3): Official · Guide / Components (zh-CN) · GitHub
• Full links and usage: 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 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 components: Split the design into separate .vue files; avoid one giant SFC.
• Logic isolation: Put event handlers and composables in src/composables/ or within script setup.
• Data decoupling: Move static text, image URLs, and lists into src/data/mockData.js (or .ts).
• Vant 4 only (use framework components when available): Use van-cell-group (inset) for card-like sections, van-field for form hints; do not use div.card or custom .card-header/.tips-text. Use <van-*> components per references/contract.md; mobile-first (375px base), safe area, flex layout.
• Project-specific: Omit third-party license headers from generated components.

Execution Steps

1. Environment: If the project has no node_modules, run npm install.
2. Data layer: Create src/data/mockData.js from the design content.
3. Component drafting: Use resources/component-template.vue as base; replace placeholder with real component name and Vant 4 tags per contract.
4. Wiring: Update the app entry (e.g. App.vue or router) to render the new components.
5. Quality check: Verify against resources/architecture-checklist.md; run npm run dev to confirm visually (mobile viewport).

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-vant constraints, map to Vue SFC and Vant 4 components. If converting from Stitch HTML (e.g. get_screen htmlCode), use references/tailwind-to-vant.md for Tailwind utility → px/theme, then 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 Vant tokens.

Troubleshooting

• Fetch errors: Quote the URL in the bash command; ensure scripts/fetch-stitch.sh is executable.
• Component mapping: Follow references/contract.md for buttons (van-button), forms (van-form, van-field), nav (van-nav-bar, van-tabbar), cells (van-cell-group), cards (van-card), submit bar (van-submit-bar).

能力边界

✅ 适用场景

• 当你需要使用此技能对应的技术栈时
• 当项目需要遵循最佳实践时
• 当需要快速上手或深入理解核心概念时

⚠️ 需要注意

• 复杂业务逻辑需要结合具体场景调整
• 性能优化需要根据实际数据量评估

❌ 不适用场景

• 不相关的技术栈或框架
• 需要完全自定义的特殊场景

常见陷阱 (Gotchas)

1. 版本兼容性：注意框架版本与依赖库的兼容性，不同版本 API 可能有差异
2. 配置文件格式：配置文件格式错误是最常见的问题，建议使用编辑器的语法检查
3. 环境变量：确保所有必要的环境变量已正确设置，敏感信息不要硬编码
4. 依赖冲突：多版本共存时注意依赖冲突，使用 lock 文件锁定版本
5. 性能陷阱：大数据量场景下注意性能优化，避免 N+1 查询等常见问题
