1. Introduction¶

ESIHub is a high-performance, feature-rich Python client for interacting with the EVE Online ESI API. It's designed to provide developers with a robust, efficient, and easy-to-use interface for building EVE Online applications.

2. Core Features¶

2.1 Asynchronous Operations¶

ESIHub is built on top of aiohttp, providing full support for asynchronous operations.

2.2 Automatic Rate Limiting¶

Built-in rate limiting ensures your application stays within EVE Online's API usage guidelines.

2.3 Caching¶

Efficient caching mechanisms reduce unnecessary API calls and improve response times.

2.4 Error Handling¶

Comprehensive error handling with custom exceptions for different error scenarios.

2.5 Logging¶

Detailed logging capabilities for easy debugging and monitoring.

3. Performance Optimizations¶

3.1 Connection Pooling¶

Optimized connection pool for efficient connection reuse and management.

3.2 Adaptive Retry Mechanism¶

Intelligent retry logic that adapts to network conditions.

3.3 Asynchronous Task Queue¶

Efficient management of concurrent requests.

3.4 Memory Usage Optimization¶

Techniques for handling large datasets without exhausting memory.

3.5 Data Compression¶

Automatic compression and decompression of request and response data.

3.6 Load Balancing¶

Intelligent distribution of requests across multiple servers.

4. Stability Enhancements¶

4.1 Circuit Breaker Pattern¶

Prevents cascading failures by failing fast when issues are detected.

4.2 Error Prediction¶

Analyzes error patterns to predict and preemptively handle potential issues.

4.3 Automatic Scaling¶

Dynamically adjusts resources based on load.

4.4 Cache Consistency¶

Ensures data integrity in the cache.

5. Advanced Features¶

5.1 SSO Integration¶

Built-in support for EVE Online's Single Sign-On system.

5.2 Webhook Support¶

Ability to send and receive webhooks for real-time updates.

5.3 CLI Tool¶

Command-line interface for quick testing and debugging.

5.4 Telemetry and Monitoring¶

Integration with OpenTelemetry for distributed tracing and Prometheus for metrics.

5.5 Automatic API Version Management¶

Seamless handling of different API versions.

6. Usage Examples¶

from esihub import ESIHubClient

async with ESIHubClient() as client:
    # Basic request
    character_info = await client.request("GET", "/characters/{character_id}/", character_id=12345)

    # Paginated request
    async for page in client.paginate("GET", "/characters/{character_id}/assets/", character_id=12345):
        print(page)

    # Batch request
    results = await client.batch_request([
        {"method": "GET", "path": "/characters/{character_id}/", "character_id": 12345},
        {"method": "GET", "path": "/corporations/{corporation_id}/", "corporation_id": 67890}
    ])

7. Best Practices¶

• Use asynchronous context managers for proper resource management.
• Implement appropriate error handling for different types of exceptions.
• Utilize caching for frequently accessed, rarely changing data.
• Monitor your application's performance using the provided telemetry and monitoring tools.
• Regularly update to the latest version of ESIHub to benefit from performance improvements and bug fixes.
