What problem does it solve?

This Skill helps engineers implement coherent, production-ready web application user journeys that span pages, routing, authentication, rendering, performance, accessibility, and browser-facing workflows, preventing fragmented implementations and usability regressions.

Core Features & Use Cases

• Journey mapping & routing: Define guarded routes, page transitions, and clear data ownership across multi-page stories.
• Auth, state & rendering: Implement secure session handling, choose SSR/CSR strategies, and apply caching and invalidation patterns.
• Performance, accessibility & testing: Enforce performance budgets, accessibility best practices, and add unit, integration, and end-to-end tests.
• Use case: Implement a secure onboarding flow with invitation token handling, guarded pages, accessible forms, appropriate rendering strategy, and end-to-end tests.

Quick Start

Implement the web application user journey for the approved story by mapping routes, adding route guards and loaders, implementing error/loading states, choosing a rendering strategy, and adding integration and E2E tests.
