kuhung/understanding-jevHTML
kuhung/understanding-jevHTMLAn index of 16 Jev design patterns, each framed as a problem you will run into, the way out, and the projects that took it. Patterns are grouped into four areas: what goes to the model, how one request is shaped, how a probability becomes an action, and how you know it holds.
