Legacy Platform Rebuild Using React & Node.js

How Elyxtech Refactored an Outdated Business Tool into a Fast, Scalable Web App

4 min read

A B2B logistics company relied on an outdated internal web tool that was slow, error-prone, and impossible to scale. Elyxtech rebuilt the platform using React for the frontend and Node.js for the backend creating a modern, responsive, and maintainable system. Delivered in under 10 weeks, the new platform increased team productivity by 40%, cut support tickets by 60%, and laid the foundation for future growth.

Challenge

FleetBase's legacy platform was:

  • Built a decade ago with outdated technologies (jQuery + PHP)
  • Buggy and difficult to maintain, with frequent crashes
  • Lacking modern UI, responsive design, and API connectivity
  • Slowing down dispatch operations and frustrating users

They needed a full platform refactor with modern best practices without disrupting their operations.

Solution

Elyxtech led the end-to-end rebuild of FleetBase’s platform, focusing on performance, scalability, and usability.

1. Platform Audit & Planning

  • Audited existing monolithic codebase and database structure
  • Identified reusable logic and risky dependencies
  • Collaborated with stakeholders to map feature priorities
  • Created migration roadmap: incremental rollout with zero downtime

2. UI/UX Redesign

  • Reimagined the user interface with Figma
  • Introduced modern design patterns: dark mode, keyboard shortcuts, dashboard widgets
  • Built a component library for future scalability
  • Ensured responsive behavior across desktop and tablets

3. Frontend Rebuild with React

  • Migrated all UIs to React + TypeScript
  • Integrated React Router for dynamic route handling
  • Optimized app performance with code-splitting and lazy loading
  • Implemented role-based access controls and dynamic dashboards

4. Backend API with Node.js

  • Rebuilt backend as modular RESTful services using Node.js + Express
  • Connected to existing MySQL database with Sequelize ORM
  • Introduced rate limiting, caching, and job queues
  • Laid groundwork for microservices migration

5. Deployment & QA

  • Used Docker for environment parity
  • CI/CD pipeline via GitHub Actions + DigitalOcean
  • Automated testing with Jest and Postman for API tests
  • Phased rollout to internal teams with feedback loops
