How to Structure a Codebase for Scale and Maintainability
Most advice about structuring a codebase assumes you are starting from an empty repository. Real work rarely looks like that. This article argues that structure is a response to a diagnosed problem, not a decision you make up front, and shows how to build the understanding that makes the decision possible.
It covers a verification loop for learning an unfamiliar system, the case for isolating business logic per endpoint (including what that approach costs), how to live with a legacy component that works but resists change, and what undocumented infrastructure does to a migration.
