Preview Import
Open and verify imported content in local development server.
When to Use This Skill
Use this skill when:
- You have generated HTML file (from generate-import-html)
- Ready to preview in browser and verify rendering
- Need to compare with original page structure
Invoked by: page-import skill (Step 5)
Prerequisites
From previous skills, you need:
- ✅ HTML file at correct path (from generate-import-html)
- ✅ Images folder in same directory
- ✅ screenshot.png from scrape-webpage (for comparison)
- ✅ documentPath from metadata.json (for URL construction)

Preview Workflow
Step 1: Start Development Server
Command:
aem up
This starts the local AEM proxy server at http://localhost:3000
Step 2: Navigate in Browser
For most files, use the document path directly:
http://localhost:3000${documentPath}
Example:
- HTML file:
us/en/about.plain.html
- URL:
http://localhost:3000/us/en/about
IMPORTANT: For index files, use /index instead of /:
If file is: index.plain.html
Preview at: http://localhost:3000/index
NOT: http://localhost:3000/
Note: If you used --html-folder flag (e.g., aem up --html-folder drafts), prepend that folder to the URL:
File: drafts/test.plain.html
URL: http://localhost:3000/drafts/test
Use paths.documentPath from metadata.json, but for index files ensure the path is /index not /
Step 3: Verify Rendering
Check the following:
- ✅ Blocks render with correct styling
- ✅ Layout matches original page structure (compare to screenshot.png)
- ✅ Images load (or show appropriate placeholders)
- ✅ No raw HTML visible
- ✅ Metadata appears in page source (view source, check
<meta> tags)
- ✅ Section styling applied correctly
Step 4: Compare with Original
Side-by-side comparison:
- Open
./import-work/screenshot.png alongside browser preview
- Check that content structure matches
- Verify blocks decorated correctly
- Confirm section boundaries align
- Validate styling consistency
Troubleshooting
Blocks don't render correctly:
- Check HTML structure matches expected format
- Verify block names match exactly (case-sensitive)
- Review
../page-import/resources/html-structure.md for format guidance
Images not loading:
- Verify images folder is in same directory as HTML file
- Check image paths are
./images/... format
- Ensure images were copied correctly from
./import-work/images/
Raw HTML visible:
- Block name might not match existing block in project
- Check browser console for JavaScript errors
- Verify block exists in
blocks/ directory
Metadata not in page source:
- Check metadata block is at end of HTML file
- View page source and search for
<meta> tags in <head>
- Verify metadata properties match expected format
Dev server not running:
- Start server with
aem up
- Check for port conflicts (default 3000)
- Verify you're in correct project directory
Page not found (404):
- Verify HTML file exists at expected path
- Check documentPath from metadata.json matches URL
- For index files, use
/index not /
- If using
--html-folder, include folder in URL
Output
This skill provides:
- ✅ Verified preview that matches original page structure
- ✅ Visual confirmation of correct rendering
- ✅ Validated block decoration
- ✅ Confirmed metadata presence
Import complete when all verification points pass.
