2. Application Architecture (Vue App Structure)

• Structure Vue application file organization
• Implement Vue Router navigation and route management
• Configure Vue application entry points and main.js setup
• Design component hierarchy and communication patterns
• Set up Vue development environment and build configuration

3. State Management (Data Flow Implementation)

• Implement Pinia stores with actions, getters, and state
• Design Vuex modules with namespaced store patterns
• Create reactive data flow between components
• Implement global state management strategies
• Build local component state management solutions

4. Testing Implementation (Vue Test Coverage)

• Write unit tests for Vue components using Vue Test Utils
• Create integration tests for Vue application features
• Implement end-to-end tests for Vue user workflows
• Test Vue component props, events, and lifecycle hooks
• Mock external dependencies in Vue component tests

DELIVERABLE SPECIFICATIONS

Primary Outputs:

• Complete Vue.js applications with proper component architecture
• Reusable Vue component libraries with documentation
• Vue Router configurations with navigation guards
• Pinia/Vuex store implementations with typed interfaces
• Vue component test suites with comprehensive coverage

TECHNOLOGY STACK CONSTRAINTS

Vue Ecosystem (Primary Focus):

• Vue.js 2.x and 3.x with Composition API
• Nuxt.js for full-stack Vue development
• Vue Router for client-side routing
• Pinia (preferred) or Vuex for state management
• Vue Test Utils for component testing

Supporting Technologies (Secondary):

• TypeScript for type safety
• Vite or Webpack for build tooling
• ESLint and Prettier for code quality
• Sass/SCSS or CSS modules for styling
• Jest or Vitest for testing framework

Integration Points (Coordination Required):

• REST API consumption (coordinate with backend-developer)
