Technologies Used

  • React.js: A powerful JavaScript library for building user interfaces, particularly single-page applications. React will be employed to create dynamic and responsive UI components that enhance user interaction.
  • TypeScript: An open-source programming language that extends JavaScript by adding static type definitions. TypeScript enables the development of clearer and more robust code, making debugging and maintenance more efficient.
  • Ruby on Rails: While the primary focus is on refactoring the frontend, a solid understanding of the existing Ruby on Rails backend is essential. Rails is a server-side web application framework written in Ruby, following the model-view-controller (MVC) architecture, which organizes application logic and facilitates data management.

Changes Made

1. Expandable Sections for Better Organization: The transition of the questionnaire UI frontend from its original non-TypeScript state to now fully incorporating TypeScript has been completed successfully, enhancing the code's reliability and ease of maintenance.

2. Global Expand/Collapse Functionality: The 'Questionnarie' user interface have been rebuilt using React.js and Typescript, ensuring dynamic and responsive behavior. The React components created are modular, reusable, and effectively manage state.

3. Improved Search functionality: An in-depth analysis and comprehension of the current Ruby on Rails backend were attained to ensure the seamless integration and functionality with the new TypeScript and React.js frontend.
