Next.js: Parallel и intercepting routes — компромиссы и trade-offs

Parallel routes — для независимых dashboard sections; intercepting — linkable modals; простой modal — useState.

Разбор

• Parallel routes для genuinely independent sections — каждый stream/error отдельно, conditional slots (@login vs @dashboard) без route juggling. Cost — conceptual overhead + mandatory default.tsx.
• Intercepting — shareable, refresh-safe modals — killer feature vs client-state modal (reload теряет content, no link). Но (.)/(..) relative к route structure, не file — wrong dots maddening to debug.
• Когда НЕ использовать: modal без URL — просто useState. Intercepting там — over-engineering. Когда content must be linkable and refresh-safe.

Итог

Use when URL/share matters; skip for ephemeral UI without deep linking.
