JavaScript YAML Configuration Reference

You can define a JavaScript client extension with a client-extension.yaml file.

Usage Details

This client-extension.yaml file defines a JavaScript client extension:

able-global-js:
   name: Able JS
   scriptElementAttributes:
      async: true
      data-attribute: "value"
      data-senna-track: "permanent"
      fetchpriority: "low"
   type: globalJS
   url: global.js

The required url property defines the JavaScript resource file’s location. When enabled on a page, JavaScript at this path runs on each page load.

The example workspace includes a complete JavaScript client extension.

These properties are specific to JavaScript client extensions:

Name	Data Type	Description
