I’m reading simultaneously @htmx.org book on hypermedia and recent @danabra.mov articles on React Components. I highly recommend that, as it gives a lot food for thoughts. Good design exercise to think about the pieces those concepts overlap and how they differ.

The pendulum swung back! Now, the "modular monolith first" is the best advice. But is it? It sounds great in theory but can fall short in practice. In practice, too often: module boundaries erode, resource isolation is absent, and that promised "easy split" rarely happens. 1/
