[irfandoart1626]

Summary

This PR implements the Allo Bank frontend technical assignment using Vue 3, TypeScript, Vite, and Vuetify.

Features

• Display rocket list from the SpaceX API
• Show rocket image, name, and description on the list page
• Filter rockets by keyword, status, and source
• Add new rocket through a local draft flow
• View rocket detail page with:
  • image
  • name
  • description
  • cost per launch
  • country
  • first flight

Technical Notes

• Implemented routing for list and detail pages
• Implemented centralized state management using Vue reactivity
• Implemented lifecycle-based data fetching
• Added reusable components for cards, filters, dialogs, and state handling
• Added UI states for loading, error/retry, empty state, and success flow

Validation

• npm run build
• npm run lint

Assumptions

• Add Rocket is implemented as a local draft stored in client state and localStorage because the public SpaceX API used in this assignment is read-only.
