# HTML Exporter Build-time helper for exporting finished HTML output directories to PDF, PNG, and WebP without modifying the source HTML. ## Core contract - Use Chromium/Playwright for rendering. Do **not** use WeasyPrint/wkhtmltopdf for `:has()` theme outputs. - Treat source HTML as read-only. Do not inject JS or write generated `.html` outside `exports/`. - Write artifacts only under `<output_dir>/exports/{pdf,png,webp}/` plus `<output_dir>/exports/export-manifest.json`. - Request themes `light,light2,white,dark,dark2,blue,skyblue,sepia` by default; capture only DOM radios that exist: `input[name="ahf-theme"]#ahf-<theme>`. - Hide export controls at render time only: `.ahf-themebar`, `.reading-progress`, `.skip`, `.ahf-color-audit`. - Confirm regression safety from manifest: `html_sha256_unchanged`, `sources_sha256_unchanged`, `validate_issues_unchanged`. ## Quick workflow 1. Identify the output directory, usually `output/<name>`. 2. If the project already has `scripts/export_output.mjs`, use it. Otherwise copy this skill's `scripts/export_output.mjs` into the project `scripts/` directory. 3. Ensure `package.json` contains: - script: `"export:output": "node scripts/export_output.mjs"` - dependency: `"playwright"` - optionalDependency: `"sharp"` - no root `"type":"module"` required. 4. Run install if needed: ```bash npm install ``` 5. Export: ```bash npm run export:output -- output/<dir> --clean ``` 6. Report: - command used and exit code - manifest
