Manifest & .trex
The XML that points Tableau at your extension, element by element.
- Encoding icon tokens for viz extensionsThe complete list of encoding-icon tokens a Tableau viz extension can use on a Marks-card tile, which ones are proven, and why line and detail are rejected.
- Local vs hosted .trex manifestsKeep two manifests that differ by one line: localhost for dev, HTTPS for production. Why Tableau demands HTTPS, and how ext-host rewrites the URL.
- The .trex manifest referenceEvery rule the .trex manifest must follow: child order, id and version patterns, the four-encoding cap, min-api-version floors, and icon size.
- What is actually inside a .trex fileA .trex is twenty lines of XML doing one job: pointing Tableau at a URL. Every element explained, why order matters, and the empty tag that breaks first loads.
