Overview

Autostrada is a comprehensive web performance monitoring platform designed to help developers and organizations track, analyze, and improve their website performance. The frontend component serves as the user interface and dashboard for the entire system, allowing users to:

  1. Monitor website performance metrics over time
  2. Analyze performance data through intuitive visualizations
  3. Track Core Web Vitals and other important performance indicators
  4. View detailed performance reports for specific URLs and pages
  5. Manage performance scanning configurations and schedules

Architecture

The frontend is built as a modern React application using TypeScript and follows a clean, modular architecture to ensure maintainability and scalability. Key architectural components include:

Component Structure

  • Layout Components: Define the overall structure of the application, including the main navigation, sidebar, and content areas
  • Page Components: Implement specific views such as dashboards, reports, and configuration interfaces
  • UI Components: Reusable interface elements like tables, charts, and form controls
  • Hooks: Custom React hooks that encapsulate complex behaviors and state management

State Management

The application uses Redux for global state management, with the following key features:

  • Redux Store: Central state container organized by domain (users, scans, metrics, etc.)
  • Redux Saga: Middleware for handling side effects, API calls, and asynchronous operations
  • Selectors: Memoized functions for efficient state derivation and component updates

Routing

React Router is used for navigation, with routes defined in a centralized configuration:

  • Public Routes: Login and authentication pages accessible to all users
  • Private Routes: Protected content requiring authentication
  • Nested Routes: Hierarchical navigation within major sections of the application

API Integration

The frontend communicates with the backend service through a custom API client:

  • REST Endpoints: For standard data operations (GET, POST, PUT, DELETE)
  • Real-time Updates: For live data monitoring using server-sent events (SSE)
  • Authentication: Token-based auth flow using AWS Cognito

Key Features

User Authentication and Authorization

  • Single Sign-On: Integration with AWS Cognito for secure authentication
  • Role-Based Access: Different permission levels for various user roles
  • Team Management: Support for multi-user teams and organizations

Performance Dashboard

  • Overview Metrics: At-a-glance view of key performance indicators
  • Time-based Analysis: Historical trend visualization
  • Comparative Views: Side-by-side comparison of different time periods or URLs

Scan Management

  • Scan Configuration: Interface for setting up and configuring scans
  • Scheduling: Tools for setting up recurring or one-time performance tests
  • Results Tracking: Monitoring scan status and viewing results

Report Generation

  • Detailed Reports: Comprehensive performance analysis for specific URLs
  • Exportable Data: Options to export reports in various formats
  • Sharing Capabilities: Tools for sharing reports with team members

Feature Flagging

  • Phased Rollouts: Support for gradual feature releases
  • A/B Testing: Infrastructure for testing different UI variations
  • User Targeting: Ability to enable features for specific user segments

Technology Stack

  • Core Framework: React with TypeScript
  • State Management: Redux and Redux Saga
  • Routing: React Router
  • UI Components: Radix UI, combined with Tailwind CSS
  • Authentication: AWS Amplify and Cognito
  • HTTP Client: Axios for API requests
  • Data Visualization: Recharts and ApexCharts
  • Build Tools: Vite

Best Practices

Coding Standards

  • TypeScript for type safety and better developer experience
  • Component-based architecture for reusability
  • Clean code principles with descriptive naming and focused responsibilities
  • Comprehensive JSDoc comments for better documentation

Performance Optimization

  • Memoization of expensive computations using React.memo and useMemo
  • Lazy loading of route components to reduce initial bundle size
  • Efficient re-rendering through proper state management
  • Resource optimization for faster loading times

Accessibility

  • ARIA attributes for enhanced screen reader compatibility
  • Keyboard navigation support for all interactive elements
  • Color contrast compliance with WCAG guidelines
  • Responsive design for various screen sizes and devices

Internationalization

  • Support for multiple languages using i18next
  • Locale-specific formatting for dates, numbers, and currencies
  • Right-to-left (RTL) text direction support where needed

Deployment Strategy

The frontend is deployed as a static web application using:

  • CI/CD Pipeline: Automated testing and deployment via GitHub Actions
  • Infrastructure: Hosted on AWS using S3 for storage and CloudFront for distribution
  • Environment Configuration: Environment-specific variables for dev, staging, and production

Future Roadmap

  • Enhanced mobile experience with responsive optimizations
  • Additional visualization options for performance metrics
  • Integration with more third-party analysis tools
  • Advanced notification system for performance regressions
  • Customizable dashboards and report templates
