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:

bash

aem up --html-folder {dirPath}

Examples based on imported content location:

HTML File Location	Command	Preview URL
`us/en.plain.html`	`aem up --html-folder us`	`http://localhost:3000/us/en`
`products/widget.plain.html`	`aem up --html-folder products`	`http://localhost:3000/products/widget`
`blog/2024/post.plain.html`	`aem up --html-folder blog`	`http://localhost:3000/blog/2024/post`

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:

code

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:

code

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:

code

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:

•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):

•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 /index not /
•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.
