    Project mention: How To Introduce a New API Quickly Using Micronaut | dev.to | 2025-05-28

    The beta version was able to generate the expected Quote model object, but I ran into issues trying to generate an interface or abstract class that my controllers could extend. So I decided to create an issue in the openapi-generator library (link for those who are interested in the details) and pivot toward another approach.

    Telosys Command Line Interface - Code Generator for any language with any framework

    Project mention: Dashboard of open source low-code tools | dev.to | 2024-11-24

    In fact, there are a few. For instance, Telosys (that we also covered here). But Telosys defines itself as a "lightweight and pragmatic code generator", not as a low-code tool. Once again, the diverse terminology in our area makes a small domain even smaller and hides useful tools from potential users that are using the "wrong" keywords. To read mode about the relationship between the low-code and model-driven communities, take a look at our work on a Metascience Study of the Adoption of Low-Code terminology in Modeling Publications, which we are now updating and extending as I still believe it's an important discussion to have in our community.
