Design-first APIs
Since Roaster was released in January of 2021 it has gained some traction within the eXist-db community. Because of the paradigm shift naturally this was adopted first by new projects, like tuttle and jinks.
But there is interest to migrate existing applications to this new model, as it has proven itself in production.
In this talk I will
- highlight the possibilities and benefits of a design-first approach when designing APIs
- present the issues we faced and the learnings we got out of solving them developing Roaster for several years
- show an entirely new tool OAD which is also the basis for the new direction the project is heading
