Frontend Architecture

The frontend architecture of the HR Management System (HRMS) will be built using a monorepo approach, which allows managing multiple frontend projects within a single repository. This architecture promotes reusability, scalability, and flexibility, enabling teams to leverage different tech stacks for individual modules while maintaining consistency across the system.

Key Features of the Frontend Architecture​

1. Monorepo Structure​

  • Unified Repository: A single repository contains all frontend projects and shared libraries.
  • Independent Modules: Each project (e.g., Employee Management, Recruitment, etc.) is self-contained and can be developed, tested, and deployed independently.

2. Tech Stack Flexibility​

  • Each project can adopt its own tech stack, such as:
    • React for modern UI development.
    • Angular for enterprise-scale applications.
    • Vue for lightweight and simple UIs.
  • Modules remain independent while coexisting in the same monorepo.

3. Shared Component Library​

  • Reusable Components: Common UI elements (e.g., buttons, input fields) can be developed as Web Components or framework-specific wrappers.
  • Design Consistency: Centralized design tokens (e.g., colors, typography) ensure uniform branding across projects.
  • Framework-Agnostic: Built with technologies like Lit or Stencil, enabling cross-framework compatibility.

4. Micro Frontends​

  • Decentralized Development: Modules are built as micro frontends and integrated into the main application.
  • Independent Deployment: Each module can be updated and deployed without affecting others.
  • Integration: Tools like Webpack Module Federation or Web Components can be used for seamless integration.

5. State Management​

  • Module-Specific State: Each module uses a state management solution suited to its tech stack.
  • Shared State: Modules communicate with each other through APIs or event-driven systems.

6. API Gateway Integration​

  • All frontend modules interact with the backend through a centralized API Gateway.
  • The API Gateway ensures secure and consistent communication between frontend and backend.

7. Performance Optimization​

  • Code Splitting: Load only the required code for each module to reduce initial load times.
  • Lazy Loading: Modules and components are loaded on demand.
  • Build Optimization: Use tools like Webpack for efficient builds.

8. Developer Experience​

  • Tooling: Tools like Nx, Turborepo, or Lerna simplify monorepo management.
  • Consistency: Shared linting, formatting, and testing configurations ensure code quality.
  • Documentation: Comprehensive documentation for shared libraries and modules accelerates onboarding.

Advantages of This Architecture​

  1. Scalability: Modules can scale independently, allowing teams to manage large applications efficiently.
  2. Flexibility: Different tech stacks can be used to suit specific requirements while maintaining integration.
  3. Reusability: Shared libraries and components reduce duplication and ensure consistency.
  4. Ease of Maintenance: Centralized management simplifies updates, bug fixes, and enhancements.
