Migrating a large-scale application from Vue 2 to Vue 3 presents a choice: persist with the Options API or adopt the Composition API.
The Composition API excels in logic reuse and code organization. Rather than scattering component logic across data, methods, and computed, it allows for grouping logically related code streams into self-contained composables.
This architectural shift provides much better TypeScript inference and reduces boilerplate, essentially enabling highly testable and loosely coupled frontend logic.
