🏢 Real Estate Syndicator Engine

A production-grade data syndication engine that transforms property and unit data into standardized feeds for external platforms such as Apartments.com and Liv.Rent.

Built with a focus on data integrity, availability accuracy, and reliable feed delivery.

---

🚀 Overview

This system ingests raw property and unit data, normalizes it into a canonical structure, applies validation and availability logic, and outputs structured XML feeds for third-party listing platforms.

It is designed to:

• Prevent invalid or incomplete listings
• Ensure accurate availability filtering
• Provide consistent, partner-ready feed formats
• Support secure, authenticated feed access
• Scale across multiple listing platforms

---

⚙️ Core Features

🧠 Canonical Data Pipeline

• Normalizes external data into a unified schema
• Handles fallback logic (e.g., property → unit fields)
• Decouples source data from feed generation

---

📅 Availability Engine

• Determines real-time availability based on:
  • explicit availability flags
  • availability dates
• Prevents future or invalid units from being published

---

✅ Validation Layer

• Ensures only publishable units are included
• Automatically blocks:
  • missing property references
  • missing rent values
• Tracks blocked vs published records

---

🧾 Feed Generation

• Generates XML feeds for:
  • Apartments.com (MITS format)
  • Liv.Rent
• Includes:
  • record counts
  • blocked counts
  • structured property + unit data

---

🔐 Authentication

• Protected feed endpoints (Basic Auth)
• Prevents unauthorized access to partner feeds

---

GET /feeds/apartments/full.xml

Liv Rent Feed (Protected)

GET /feeds/liv-rent.xml Authorization: Basic Auth required

Optional query:

?available=true

Returns only currently available units.

---

🧪 Test Suite

This project includes a full Jest + Supertest test suite covering core business logic and API behavior.

✅ Unit Tests

• Availability logic (isAvailableNow)
• Validation rules (validateUnit)
• Normalization fallback behavior

🔌 Integration Tests

• Feed endpoints return valid XML
• Availability filtering works end-to-end
• Canonical data service is invoked correctly

🔐 Authentication Tests

• Unauthorized requests are rejected
• Authorized requests succeed

📊 Test Coverage

• 6 test suites
• 21+ test cases
• Covers:
  • business logic
  • API behavior
  • auth enforcement
  • data transformation

🧠 Design Principles
Deterministic outputs
Tests do not depend on live external data
Separation of concerns
Data → normalization → validation → feed generation
Fail-safe validation
Invalid data is blocked, not published
Test-driven confidence
Core logic and endpoints are protected by tests
Production-ready structure
Designed for scalability and multi-platform expansion
📈 Real-World Impact
