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 with HTML Folder Flag

Determine the folder from metadata.json:
- Look at paths.dirPath from metadata.json (e.g., /us)
- This is the root folder containing your imported HTML file

Command:

aem up --html-folder {dirPath}

Examples based on imported content location:

Why this is required:
- Without --html-folder, AEM CLI proxies requests to the remote server
- The remote server doesn't have your locally imported content
- Result: 404 "Page not found" errors

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 / instead of /index:

If file is: index.plain.html
Preview at: http://localhost:3000/
NOT: http://localhost:3000/index

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 / not /index

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:
1. Open ./import-work/screenshot.png alongside browser preview
2. Check that content structure matches
3. Verify blocks decorated correctly
4. Confirm section boundaries align
5. Validate styling consistency

Troubleshooting

Blocks don't render correctly:
- Check HTML structure matches expected format
- Verify block names match exactly (case-sensitive)
- Review ../content-driven-development/references/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):
- Most common cause: Missing --html-folder flag - restart server with aem up --html-folder {dirPath}
- Verify HTML file exists at expected path
- Check documentPath from metadata.json matches URL
- For index files, use / not /index
- Check terminal output confirms "Serving HTML files from folder: {folder}"

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.
