App Review: Text Media JSON Mock

Loaded Source URL

Summary of App Behavior

This app loads a JSON file from a given URL and renders it as a card-based article viewer, mimicking the MediaWiki parse API format. Users can paste a JSON URL and click "Load JSON," use built-in demo data, or load a single HTML file. When demo data is loaded, the Reader View displays a formatted Wikipedia-style article — in this case about Kiviak, a traditional Inuit fermented food — with sections like a summary card, Quick Facts table, and Overview. An Article Map on the left is meant to show a section index.

Things That Did Not Work as Expected

• The Article Map panel remained empty and unhelpful even after JSON was loaded — it just says "Load JSON to build the section index" without ever populating a clickable index.
• The layout with Article Map on the left felt confusing since it never actually showed any content, making it look like a broken feature rather than a navigation aid.
• There is no indication of what JSON URLs are valid beyond the placeholder example, which could confuse new users trying to load their own data.
• The "Single HTML file" button's purpose is unclear — no tooltip or explanation is provided.

Suggested Improvement Prompt

• Fix the Article Map so it automatically populates with clickable section headings once JSON is loaded, allowing users to jump to each section.
• Add a loading indicator while JSON is being fetched from a URL.
• Add a tooltip or helper text explaining what the "Single HTML file" button does.
• Add error handling that shows a friendly message if the JSON URL is invalid or the structure does not match the expected format.
