Overview

Studio is built on several core architectural concepts that enable scalable, maintainable component development. Understanding these patterns is essential for building custom UIs that leverage Studio's architecture.

Studio's architectural foundation and design patterns

Architectural Layers

Studio follows a layered architecture that separates concerns and enables component reusability:

1. Data Layer (Composables)

Reactive state management and API integration using Vue Composition API.

How composables manage state and API communication

Key Characteristics:

• Reactive State: Uses Vue refs and computed properties
• API Abstraction: Centralized API communication patterns
• Error Handling: Consistent error states and loading indicators
• Type Safety: Full TypeScript integration with API types

Example Composables:

• useWorkspaces() - Workspace management and selection
• useMetrics() - Metric CRUD operations and validation
• useDashboards() - Dashboard creation and execution
• useApi() - Base API client configuration

2. Component Layer (UI Components)

Modular, reusable components organized by domain and complexity.

Component organization and dependency relationships

Component Categories:

• Atomic Components: Basic UI elements (buttons, inputs, cards)
• Domain Components: Business logic components (MetricDialog, DashboardWidget)
• Builder Components: Complex form builders (MetricSchemaBuilder)
• Layout Components: Page structure and navigation (Sidebar, containers)

3. Page Layer (Route Components)

Route-specific compositions that orchestrate components and state.

How pages compose components and manage routing

Page Responsibilities:

• Route Management: Handle navigation and URL parameters
• State Orchestration: Coordinate multiple composables
• Component Composition: Arrange components for specific workflows
• Layout Definition: Define page-specific layouts and sidebars

Design Patterns

Builder Pattern

Studio uses the Builder pattern extensively for complex configuration interfaces.

How builders compose to create complex forms

Implementation:

• Modular Builders: Separate builders for different concerns (measures, dimensions, filters)
• Shared State: Reactive form state managed across builder components
• Validation: Real-time validation with user feedback
• Preview: Live preview of configurations

Key Builders:

• MetricSchemaBuilder - Orchestrates all metric configuration builders
• MeasuresBuilder - Handles quantitative measure definitions
• DimensionsBuilder - Manages categorical dimension setup
• FiltersBuilder - Configures data filtering conditions

Composition Pattern

Components are designed to be composed together for maximum flexibility.

Component composition and prop passing patterns

Composition Principles:

• Single Responsibility: Each component has a focused purpose
• Props Interface: Well-defined props for component communication
• Event Emission: Components emit events for parent handling
• Slot Utilization: Flexible content injection via slots

Dialog Pattern

Consistent modal interfaces for all CRUD operations.

Standardized dialog interfaces and interactions

Dialog Features:

• Consistent UX: Standardized create/edit/delete flows
• Form Validation: Integrated validation with error display
• Loading States: Visual feedback during operations
• Responsive Design: Adaptive layouts for different screen sizes

Dialog Types:

• Create Dialogs: For new resource creation
• Edit Dialogs: For existing resource modification
• Delete Confirmations: For destructive actions
• Complex Builders: For multi-step configurations

State Management Philosophy

Studio adopts a composable-first approach to state management without external state libraries.

Reactive State

How reactive state flows through the application

State Characteristics:

• Local First: Components manage their own state when possible
• Shared via Composables: Global state managed through composables
• Computed Properties: Derived state using computed refs
• Watchers: Side effects handled through watchers

Context Management

Studio handles multi-tenant context (workspaces/environments) throughout the application.

Workspace and environment context flow

Context Features:

• Workspace Selection: Global workspace context
• Environment Switching: Environment-specific configurations
• Route Protection: Redirect logic for unconfigured contexts
• Persistent State: Context preserved across sessions

Type System

Studio leverages TypeScript extensively for type safety and developer experience.

Interface Design

TypeScript interface organization and relationships

Type Organization:

• API Types: Response and request type definitions
• Component Props: Strongly typed component interfaces
• Composable Returns: Type-safe composable return values
• Event Handlers: Typed event emission and handling

Validation Integration

How TypeScript types integrate with runtime validation

Validation Features:

• Schema Validation: Zod schemas for runtime validation
• Form Validation: VeeValidate integration with TypeScript
• API Validation: Type-safe API communication
• Error Handling: Typed error states and messages

Performance Patterns

Lazy Loading

Studio implements lazy loading for optimal performance.

Lazy loading strategies for components and routes

Loading Strategies:

• Route-Based: Pages loaded on demand
• Component-Based: Heavy components loaded when needed
• Data-Based: API calls triggered by user interaction
• Asset-Based: Images and charts loaded progressively

Reactivity Optimization

Optimizing reactive state for performance

Optimization Techniques:

• Computed Caching: Expensive computations cached automatically
• Shallow Refs: Optimize arrays and objects with shallow reactivity
• Watch Debouncing: Prevent excessive API calls
• Component Memoization: Avoid unnecessary re-renders

Testing Philosophy

Studio's architecture enables comprehensive testing strategies.

Component Testing

Testing strategy for components and composables

Testing Approaches:

• Unit Testing: Individual component functionality
• Integration Testing: Component interaction patterns
• Composable Testing: State management and API integration
• Type Testing: TypeScript interface validation

Best Practices

Component Design

Guidelines:

1. Single Responsibility: Each component should have one clear purpose
2. Props Validation: Use TypeScript interfaces for prop definitions
3. Event Naming: Use consistent event naming conventions
4. Accessibility: Implement ARIA labels and keyboard navigation
5. Performance: Optimize for large datasets and complex interactions

State Management

Guidelines:

1. Local State First: Keep state as local as possible
2. Composable Abstraction: Extract reusable state logic to composables
3. Type Safety: Maintain strong typing throughout state flow
4. Error Boundaries: Handle errors gracefully with user feedback
5. Loading States: Provide visual feedback during async operations

API Integration

Guidelines:

1. Consistent Patterns: Use established composable patterns
2. Error Handling: Implement comprehensive error states
3. Caching Strategy: Cache responses appropriately
4. Type Validation: Validate API responses at runtime
5. Retry Logic: Handle network failures gracefully
