Refactor: Migrate JavaScript (JS/JSX) codebase to TypeScript (TS/TSX)

srilatha bandari requested to merge feat/web into develop

Overview

This Merge Request introduces a full migration of the codebase from JavaScript (JS/JSX) to TypeScript (TS/TSX). The objective of this refactor is to enhance code quality, enforce type safety, and improve long-term maintainability without altering existing functionality or user experience.

The migration has been carried out incrementally to ensure stability, with careful attention to preserving current behavior while introducing type definitions and improving developer tooling.

Objectives

  • Introduce static typing across the codebase
  • Improve reliability by catching errors at compile time
  • Enhance developer productivity with better IDE support
  • Establish a scalable and maintainable code structure
  • Align the project with modern frontend development standards

Scope of Changes

1. File Conversion

  • Converted all .js files to .ts
  • Converted all .jsx files to .tsx
  • Updated file extensions across imports and module references

2. Type Integration

  • Added type annotations for:

    • Functional components
    • Props and state
    • Utility functions and services

  • Introduced basic interfaces and type definitions where required

  • Reduced reliance on implicit any types

3. Configuration Updates

  • Added and configured tsconfig.json
  • Ensured compatibility with existing build tools and bundlers
  • Updated project settings to support TypeScript compilation

4. Codebase Adjustments

  • Refactored parts of the code to satisfy TypeScript constraints
  • Resolved type-related errors and warnings
  • Standardized import/export patterns where necessary

Key Benefits

  • Type Safety: Early detection of potential bugs during development
  • Improved Maintainability: Clear contracts via types make the code easier to understand and extend
  • Enhanced Developer Experience: Better autocompletion, navigation, and refactoring support
  • Scalability: Strong foundation for future feature development and team collaboration

Impact Analysis

  • No changes to existing functionality
  • No UI/UX modifications
  • No breaking changes introduced

This MR is strictly a refactor and does not introduce new features or alter business logic.

Testing & Validation

  • Verified successful project build after migration
  • Manually tested core application flows to ensure parity with previous behavior
  • Confirmed no runtime errors introduced due to type changes

Known Limitations

  • Some areas still use any or loosely defined types for compatibility
  • Complex modules may require further type refinement
  • Strict TypeScript rules are not fully enforced yet to avoid blocking development
