Co-locate by feature
Grouping code by feature instead of by file type keeps related logic together. When a feature changes, the edits live in one folder, and onboarding engineers can reason about a slice without spelunking the whole tree.
Keep state where it belongs
Lifting every value to a global store creates hidden coupling. We keep state as local as possible and reach for shared stores only when data genuinely spans the app. Less global state means fewer surprising bugs.
Boundaries you can test
Well-defined module boundaries let us test units in isolation and swap internals without breaking consumers. Clear interfaces are what let a codebase grow without grinding to a halt.
