Structura

AI-powered web data extraction — select text on any page, extract structured data with AI, export to CSV or Feishu Bitable.

完全符合 2026 年 Chrome Web Store 严格审查规范的开源扩展样板。

Key Design Decisions

• Manifest V3: Mandatory for all new Chrome extensions since 2023.
• No <all_urls>: activeTab + scripting grants one-shot host access only on user gesture.
• Strict CSP: script-src 'self'; object-src 'self'; blocks remote code and eval.
• Service Worker (type: module): Zero persistent background process; ES module imports supported.
• Two locales: English + Simplified Chinese i18n out of the box.
• No remote dependencies: Zero CDN, zero external fonts, zero iframes.

Permissions: Why Only These Three?

["storage", "activeTab", "scripting"]

• storage — Persist user settings and extension state.
• activeTab — Temporary host permission for the active tab, only on user gesture. The recommended replacement for <all_urls>.
• scripting — Required alongside activeTab to call executeScript().

Content Security Policy

"script-src 'self'; object-src 'self';"

Only 'self' — no CDN, no 'unsafe-inline', no 'unsafe-eval'. The popup HTML also carries a redundant <meta> CSP layer.

Cross-Browser Compatibility

Includes browser_specific_settings for Chrome (minimum_chrome_version: "120"), Edge, and Firefox (gecko UUID with strict_min_version).

2026 CWS Review Checklist

• Replace placeholder icon PNGs with production artwork
• Set author.email to your verified developer email
• Replace the gecko.id UUID for Firefox submission
• Write and host a Privacy Policy (required by CWS)
• Submit via Chrome Developer Dashboard
• Confirm the extension works fully offline (review sandbox may block network)
