We use several Devextreme features in our web (vuejs + vuetify) and I would like to use Html Editor to allow users create their own templates with variables and store them. These will then be used, populated and sent to the clients in particular situations. For example booking confirmation with the following format:

Dear {CUSTOMER_NAME}

Your booking {RESERVATION_NUMBER} has been confirmed on {CREATION_DATE} please make sure to contact us on {COMPANY_PHONE}

I am (obviously :) ) begginer and can't wrap my head around it, the output of the editor in Devextreme may be either markdown or html, which I may store in variable, populate and convert to PDF later on when is to be sent to the customer with the proper info.

But how to populate it? the part of an output is for example data-var-value="CREATION_DATE"

Any ideas would be highly appreciated
