webf-api-compatibility

SKILL.md

Note: WebF development is nearly identical to web development - you use the same tools (Vite, npm, Vitest), same frameworks (React, Vue, Svelte), and same deployment services (Vercel, Netlify). This skill covers one of the 3 key differences: checking API and CSS compatibility before implementation. The other two differences are async rendering and routing.

WebF is NOT a browser - it's a Flutter application runtime that implements W3C/WHATWG web standards. This means some browser APIs are not available, and some CSS features work differently.

This skill helps you quickly check what's supported and find alternatives for unsupported features.

检查 WebF 中的 Web API 和 CSS 功能兼容性 - 确定支持哪些 JavaScript API、DOM 方法、CSS 属性和布局模式。在规划功能、调试 API 不起作用的原因或为不支持的功能（如 IndexedDB、WebGL、浮动布局或 CSS 网格）寻找替代方案时使用。 来源：openwebf/webf。
