Extensions

qext

interface

The extension metadata file (QEXT) is a JSON file, and is used by Qlik Sense to identify the visualization extension. It contains the metadata used for the library or assets panel. When deployed to Qlik Sense, the visualization extension is displayed in the Charts section of the assets panel or library panel.

Properties

name string	This is the name of the visualization extension and is displayed in the library as well as in the preview. It is recommended to use a unique name for the visualization to avoid interference with other visualizations that may have the same name.
type 'visualization'	This defines the type of extension. It should always be `'visualization'` for visualization extensions.
description string	This defines the description visible in the preview of the visualization extension.
icon default='extension' 'bar-chart-vertical' \| 'extension' \| 'filterpane' \| 'gauge-chart' \| 'line-chart' \| 'list' \| 'map' \| 'pie-chart' \| 'scatter-chart' \| 'table' \| 'text-image' \| 'treemap'	This defines the icon displayed in the library.
preview string	This defines which preview image is to be used. The preview image is displayed in a pop-up when you select the visualization extension in the library.
version string	This defines your individual version handling of the visualization extension. This setting is manually defined. Semantic versioning is recommended.
author string	This defines the author of the visualization extension. This setting is manually defined.

```json
{
  "name": "Hello World",
  "description": "Hello world example",
  "preview": "helloworld.png",
  "type": "visualization",
  "version": 1,
  "author": "Qlik International"
}
