Modernization of IBM Notes/Domino applications should be done outside of the Notes/Domino universe, which means in the first step to create a non-xpage frontend and connect it to your existing Notes application. I’m currently working in multiple projects with Vaadin and I’ve created a step-by-step tutorial as a beginners guide to start with Domino application modernization using REST, Spring Boot and Vaadin.
It is not a deep dive into all involved technologies and frameworks. The intention was to create a step-by-step guide for a classic Domino developer now looking forward to modernize applications with new technologies. Not discussing every single topic and technology in detail, just something to get startet und to get a working example without much effort.
If you have questions or in case of any problems and errors, don’t hesitate to contact me!
