Using a running tracker app as a concrete example, the key differences between a regular monolith and a modular monolith are demonstrated: in a regular monolith, bounded contexts slowly bleed into each other through direct entity references and database joins, making future extraction painful. In a modular monolith, each module owns its domain, infrastructure, and a clearly defined public API that is the only allowed coupling point between modules. This approach enables easier extraction into microservices later, better control over side effects, and optional database-level access policies per schema. ## Full article daily.dev links to this article rather than hosting it.
