Introduction

Expertiza is an open-source learning management system developed with Ruby on Rails. It provides a robust suite of features designed to enhance the educational experience, including the creation of assignments, assessments, teams, and courses. One of its standout capabilities is a comprehensive peer review mechanism that facilitates detailed feedback within teams and among group members, fostering collaborative learning.

The current focus of the Expertiza project is to modernize its frontend components, particularly the Questionnaire interface. This initiative aims to transform the existing non-Typescript UI into a more efficient and maintainable Typescript-based system. The team is tasked with designing and implementing the User Interface for these components using React.js and Typescript, ensuring a responsive and user-friendly experience. Additionally, the project aims to improve accessibility and enhance user engagement through a more intuitive design.

By leveraging modern web technologies, Expertiza not only seeks to improve its functionality but also to provide educators and students with a powerful tool for interactive learning and assessment.

Problem Statement

Background

The current Expertiza platform features a questionnaire user interface that is built with JavaScript, which lacks the benefits of type safety and maintainability offered by TypeScript. As a result, managing the codebase has become increasingly challenging, leading to potential bugs and hindered development. The goal of this project is to enhance the questionnaire UI by refactoring the existing code to utilize TypeScript, thereby improving code robustness and maintainability. This modernization is essential for ensuring that the platform remains efficient and user-friendly for educators and administrators.

Objective

The primary objective of this project is to refactor the existing non-Typescript front end of the questionnaire UI to leverage TypeScript. This transition aims to improve the overall maintainability and reliability of the code, while also enhancing the user experience by implementing an intuitive and efficient interface for managing questionnaires. The project seeks to ensure that all existing functionalities are preserved during the refactoring process and that the system remains responsive and effective for its users.

Key Requirements

1. Refactor the Existing Code: Convert the current JavaScript codebase to TypeScript, ensuring that all functionalities remain intact and operational post-refactor.

2. Implement TypeScript in the UI: Adapt the React-based questionnaire UI for TypeScript compatibility, which may involve rewriting certain sections of the existing code.

3. Ensure Functionality Remains Intact: Conduct rigorous testing of core functionalities, including creating, updating, and deleting entries, to confirm that they operate as expected after the transition.

4. Update the JSON Server: Verify that the mocked JSON server for data handling continues to function correctly with the new TypeScript implementation.

5. Comprehensive Testing: Implement a thorough testing strategy, encompassing unit tests, integration tests, and end-to-end tests to ensure the reliability of the application.

6. Documentation: Update all project documentation, including code comments and the README file, to accurately reflect the changes made during the refactoring process.


By employing modern technologies such as React.js and TypeScript, this project aims not only to enhance the questionnaire UI but also to contribute to a more interactive and efficient learning environment within Expertiza.

Expected Outcome

The project aims to enhance the questionnaire UI by refactoring it to TypeScript, resulting in improved code quality and maintainability. Users can expect a more intuitive interface with seamless functionality for managing questionnaires, while robust testing will ensure reliability. Updated documentation will provide clarity for future development, contributing to a more effective learning environment within Expertiza.

Description of the Project

Objective:

The primary aim of this project is to enhance the user interface of the questionnaire component in Expertiza by refactoring the existing non-TypeScript frontend into a modern implementation using TypeScript and React.js. This transition will improve code maintainability, robustness, and overall user experience.

Key Tasks:

1. User Authentication:
Log in as a Super Admin to access and manage the questionnaire interface effectively.

2. Refactor Questionnaire UI:
Reimplement the existing questionnaire UI using React.js and TypeScript, ensuring that all current features remain functional while leveraging the advantages of a type-safe environment.

Development Process:

1. Familiarization with the Current System:
Analyze the existing questionnaire interface within Expertiza, focusing on how data models, controllers, and views are interconnected within the Ruby on Rails framework.

2. Setup Development Environment:
Configure a TypeScript and React.js development environment tailored for building the new UI components, ensuring all necessary tools and dependencies are in place.

3. Design UI Components:
Create React components that correspond to various parts of the questionnaire interface, prioritizing state and props management for optimal component interaction.

4. Implement Components in TypeScript:
Develop the new UI components using TypeScript, ensuring that they maintain the original functionality of the questionnaire interface while enhancing code quality and reliability.

5. Integrate Components:
Incorporate the newly developed components into the main Expertiza application, verifying their compatibility with existing backend services and workflows.

6. Review and Refactor:

  • Pagination:
Implement pagination to manage the display of large sets of questionnaires, making it easier for users to navigate through the content.
  • Expand and Collapse Options:
Add functionality to expand and collapse questionnaires, allowing users to view them hierarchically. This will enhance organization and improve the overall clarity of the UI.
  • Code Quality Improvements:
Enhance the overall quality of the code by adding comments, removing obsolete code, and implementing form validations to ensure user inputs are accurate and secure.

Outcome:

The project aims to transition the Expertiza UI component for 'Questionnaire' from Ruby on Rails to a more modern, efficient TypeScript and ReactJS-based implementation, incorporating user role restrictions and various UI improvements for a better user experience.

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: Implemented collapsible sections categorizing questionnaires into types like "Review-Related," "Survey-Related," and "Specialized." Each section can be expanded or collapsed individually, providing a cleaner and more organized view.


2. Global Expand/Collapse Functionality: Added “Expand All” and “Collapse All” buttons for efficient management, allowing users to view all sections or hide them with a single click.


3. Improved Search functionality: Retained a streamlined search bar at the top to filter questionnaires quickly across all categories.


4. Pagination and Customizable Display limits: Introduced pagination at the bottom of the page, with options to adjust the number of items displayed per page (e.g., 10, 25, 50), enhancing usability when dealing with numerous questionnaires.

6. Category-Based Expansion:: Each questionnaire type within a section (e.g., “ReviewQuestionnaire,” “MetareviewQuestionnaire”) can be expanded to reveal more options or details, giving users quick access to specific items without cluttering the main view.


7. UI Consistency and Improved Accessibility: Ensured that the updated UI aligns visually with the Expertiza platform’s color scheme and layout. Buttons and action items are clearly distinguishable, with accessible labeling for ease of use.

Testing

Testing was initially excluded from the project's scope, as the focus was on frontend development. Nevertheless, ensuring the functionality and user experience of a website's interface is crucial. Therefore, manual testing procedures will be used to validate the correct operation of the UI components. These procedures include:

  1. Verifying all the added button links to ensure they function correctly.
  2. Testing whether the Search Bar accurately searches the matching questionnaire.
  3. Testing whether sorting functionality displays the result in correct ascending and descending order.
