Creating Adobe Launch Extension : Other features

On this article, I will explain some addition features that are integrated within the creation of your Launch extension.

Those features are less developed in our case because they don’t require a lot of customization usually.
You can, obviously, develop these features into more advanced use-cases but this is not a must to know and develop.


This element is at the root of your Extension folder and contains all of your extension path and details of your extension.

In this manifest, you can change the name of your extension, its description and configuration.
It is important that this manifest is up to date before you are creating your package for the upload.
Every time that you are uploading a new version, make sure that you increase your versioning in your manifest. This will trigger the possibility to upgrade the Extension.

There is a clear description of what is possible to be configured on this file available on the Launch Developer website :

For this file, if it is not required to be modified, it is very encouraged to be checked and the documentation read.

Icon for Extension

One of the possible modification within the extension.json, is to add the path to the icon of your extension. The icon represents your graphical identity, you may want to have some thought on which design or color to use. The icon has to be on the svg format.

In order to change that, you would just need to add your path to your icon within the file :

 "iconPath": "resources/icons/myIcon.svg",

Turbine Free Variables

The turbine free variables are quite important as you may have noticed when we were coding the different part of our extension. These variables are available only on runtime. This means that they can be accessed in your .js files only!
Those variables provide information and utilities specific to the Launch runtime and is always available to library modules.

There is a complete description of their possibilities here : Turbine Free Variables

However we will cover the most important ones:

  • turbine.getDataElementValue(name: string) : return the value of a Data Element
  • turbine.getExtensionSettings() : returns the object set by your extension settings.


In the case that you are publishing a public extension, you would need to register to Adobe Exchange in order to give a proper page information about your Extension.
Within the exchangeUrl, you will give the URL of your extension’s listing on Adobe Exchange.

Core Module functionalities

Adobe reactor engines provide a list of functionalities that you are able to use within your extension. Those are some helper methods, if you would like to realize some operations, they can be handy.

Complete list is available here : Launch Core Module Functions

Here what kind of operation, they can help you realize :

  • Set or Read a cookie (@adobe/reactor-cookie)
  • Read queryString (@adobe/reactor-query-string)
  • Read document information at runtime (@adobe/reactor-document)
  • Use a promise (@adobe/reactor-promise)

You can see in the action module that I use one of the core component to display a console where you can save your comments.

I hope that this is giving you a good overview on what is available.
It is quite difficult to cover the full range of functionalities provided but it would not have been complete if I didn’t mention those functionalities.
