Phillips Education – Program Management Dashboard

A modern React 19 application enabling Education Supervisors to curate custom learning paths with a hybrid data architecture.

📋 Executive Summary

The Phillips Education POC solves a critical gap in enterprise learning management: supervisors cannot currently curate training paths or enroll employees in custom programs. This application delivers a self-service program builder that decouples assignment (supervisor says "Do this") from registration (employee picks "Nov 20th in Mumbai"), enabling supervisors to build, publish, and manage learning programs while students independently select enrollment dates and locations.

🎯 Key Features

Visual Program Builder

Drag-and-drop curriculum design using @dnd-kit. Supervisors search, filter, and compose custom learning paths from existing course catalogs with real-time duration calculations (ILT days + eLearning hours).

Hybrid Data Layer

Reads from legacy Phillips APIs (Azure cloud) while persisting new logic to a local microservice layer (json-server). A network-first, localStorage-fallback strategy ensures seamless operation in offline mode or when APIs become unavailable.

Modern Responsive UI

Fully responsive dashboard built with shadcn/ui primitives and Tailwind CSS v4. Features include horizontal course "ticket" cards, 2-column modal layouts, and Radix UI accordion components for accessibility-first design.

Resilient Persistence

Network-first architecture with localStorage fallback. Perfect for Vercel deployment—automatically detects offline mode and gracefully degrades to local data without requiring API infrastructure.

Student Experience

Multi-step enrollment flow: students view assigned programs, book classes at specific dates/locations, and track progress with interactive status badges. Demo mode allows supervisors to showcase workflow without modifying data.

Hybrid Data Model

Entity	Source	Write Target	Purpose
Courses	Legacy Phillips API (Azure)	Read-only	Course metadata, pricing, skills

🚀 Getting Started

Prerequisites

Bun (or Node.js 18+)
Git

Quick Start (3 steps)

# 1. Install dependencies
bun install

# 2. Start dev environment (Vite + json-server)
bun dev

# 3. Open browser
# Vite: http://localhost:5173
# JSON Server: http://localhost:3001

That's it! The application automatically:

✅ Fetches courses from Phillips legacy API
✅ Loads mock students and assignments from db.json
✅ Falls back to localStorage if APIs are unreachable
✅ Runs in "Offline Mode" without requiring any remote connections

Additional Commands

bun run build           # Production build (TypeScript + Vite)
bun run lint            # ESLint with strict rules
bun run preview         # Preview production build locally
bun run server          # JSON Server only (port 3001)
bun run test            # Run Vitest suite

🎯 Key Technical Decisions

1. Hybrid Data Architecture

Decision: Read from Legacy API, write to json-server (+ localStorage as fallback) Rationale: Maintains single source of truth for courses while enabling new features without touching legacy systems.

2. Network-First, localStorage-Fallback

Decision: Try json-server first; if offline or unreachable, use localStorage Rationale: Enables Vercel deployment (no backend required) while maintaining data reliability in offline scenarios.

3. Variant Component System

Decision: CourseCard uses variant prop ("default" | "workbench") instead of separate components Rationale: Single source of truth, easier maintenance, and flexibility for future variants.

4. Radix UI Primitives + shadcn/ui

Decision: Use Radix UI directly for Accordion; wrap others with shadcn for Tailwind integration Rationale: Maximum control + consistency with minimal abstraction layers.

5. Lightweight Persistence

Decision: Store only course IDs in programs, not full course objects Rationale: Reduces payload size, simplifies updates (rehydrate on fetch), and maintains real-time accuracy.

📊 Data Reliability

The application implements a "Data Guarantee" pattern:

// Example: getInventory(courseId)
if (!inventory || !inventory.classes || inventory.classes.length === 0) {
  console.warn(`API returned empty for course ${courseId}, using fallback`);
  // Load fallback from Schedules.json
  return fallbackSchedules.filter((s) => s.courseId === courseId);
}

This ensures:

✅ Network errors don't break the app
✅ Empty API responses trigger fallback (not just HTTP errors)
✅ Students always see available class sessions
✅ Demo works offline without modification

🔐 Security & Deployment

Authentication

Currently mocked ("Pat Mann" logged in by default)
Ready for enterprise SSO/SAML integration

Production Deployment

Vercel: Automatic; no backend required
AWS/Azure: Add reverse proxy for Legacy API (CORS)
On-Premise: Docker-friendly (Node.js 18+)

Test Data

All mock emails use @example.com (RFC 2606 reserved)
No real PII in version control
Safe for client demos

📈 Performance

Metric	Value	Notes
