devon4j – getting started - contract first

[SchettlerKoehler]

The purpose of this tutorial is to show the user what devon4j can do and where to start when one should add business logic to a devon4j application. This tutorial should be seen as the first point of contact with devon4j. The user does not have to understand every step on the way. It is OK to tell the user that certain things are explained in later tutorials.

• devonfw ide should already be installed. Tell the user that it is already installed and where he can find the tutorial on how to do it on his local machine.
• Generate a new devon4j application from an OpenApi file. It should be a simple API with only one method e.g. a method that returns the sum of two values.
• Show the user where he can implement the business logic and let him implement the logic for the example
• Let the user run and try the new API with curl (or maybe misuse the swagger ui: https://petstore.swagger.io/?url=theUrlOfTheAPI)
• Tell the user where he could find additional tutorials and what are the next steps.
