  8. Use AWS Route 53 for domain management and DNS

Design Rationale

  • React with TypeScript was chosen for its strong typing and component-based architecture, improving maintainability and reducing bugs.
  • PostgreSQL provides robust relational data management for user and session information.
  • Redux is used for global state management, ensuring consistent data flow across the application.
  • Styled-components allows for easy theming and component-specific styling.
  • Docker containers ensure consistency across development and production environments.
  • AWS services provide scalability and reliability for handling potential growth in user base.
  • The file structure separates concerns and promotes modularity, making the codebase easier to navigate and maintain.
