Template Data Overview

The Data tab manages a JSON object that feeds both your Handlebars template and JavaScript runtime.

How Data Is Used

• Handlebars variables resolve by key name (for example {{title}}).
• JavaScript can access the same data via the global __APP_DATA__ object.

Editor Modes

• Edit: Define structure, keys, and types.
• Fill: Populate values without changing structure.
• Raw: Edit the JSON directly with validation.

Tips

• Keep the root as an object, not an array.
• Use consistent keys to make templates readable and predictable.
