HAUL

Hyperspace Asset Unloading and Loading

HAUL is my old route planner and automation tool designed for EVE Online. It simplifies asset transportation by optimizing trade routes, automatically setting waypoints in-game, and identifying profitable trade opportunities through API integrations.

Overview

HAUL is a full-stack application tailored for players of EVE Online, offering seamless route planning, waypoint automation, and trade optimization. It fetches live game data via the EVE Swagger Interface (ESI) API and utilizes modern web technologies to deliver a fast and interactive user experience.

The project comprises:

• A Python backend that handles route calculations, API calls, and real-time updates.
• A React frontend providing a clean and dynamic interface.
• An experimental Rust rewrite of the backend focused on performance improvements.

Tech Stack

Backend (Python)

• Framework: FastAPI for high-performance API development.
• Asynchronous Processing: asyncio for handling multiple concurrent API calls and tasks.
• API Integration:
  • Extensive use of the EVE Swagger Interface (ESI) API for fetching in-game data, such as trade orders, solar system details, and player locations.
• Automation: Automatically sets waypoints in the EVE Online client through API interactions.
• Streaming Data: Implements StreamingResponse to deliver real-time updates to the frontend.

Frontend (React)

• Framework: React for building dynamic, responsive user interfaces.
• State Updates: Use of both polling and server-side events to update state

Experimental Rust Backend

• A rewrite of the Python backend focused on improving performance in API-intensive operations like route calculations

Key Features

1. Route Optimization

   • Calculates the shortest and safest routes between in-game locations based on:
     • Travel time, warp speeds, and stargate connections.
     • Risk factors, including security ratings of solar systems.
   • Suggests optimized paths for asset transportation and trading.
   • Automatically sets waypoints in the EVE Online client, simplifying navigation for players.

2. Profit Optimization

   • Identifies arbitrage opportunities by analyzing buy/sell orders across regions.
   • Uses efficient filtering algorithms to recommend profitable trades.

3. Real-Time API Integration

   • Fetches live trade orders, player locations, and solar system details using the EVE Swagger Interface (ESI) API.
   • Continuously updates routes and trade data in real-time.
   • Utilizes server-sent events to deliver live updates on trade opportunities, routes, and player location changes.
