Motivation

We need support for the template language jslt to transform/modify JSON data that comes in/out. It is very handy in KameletBindings where we would support transformations of JSON data using jslt-action because currently we require the correct format between data sources and data sinks.

Expected outcomes

https://camel.apache.org/camel-kamelets/0.8.x/jslt-action.html 

Example of JSLT template:

{
    "channel":"C03Q0ENEGAU",
    "text":"*"+.from.first_name+"@telegram*: "+.text
} 

Example of KameletBinding which use jslt-action:

source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: telegram-source
    properties:
      authorizationToken: "{{secret:stage1/telegram.token}}"
 
  steps:
  - ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: jslt-action
    properties:
      template: t2s.jslt
