Summary of Changes
Hello @rm-hull, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request fundamentally re-architects the application from a command-line data processor to a high-performance web service. The core change involves implementing a spatial index to enable efficient geographical queries on UK CodePoint data, exposed through a new RESTful API endpoint. This significantly enhances the utility and accessibility of the postcode data.
Highlights
- Application Transformation: The application has been transformed from a command-line data extraction utility into a fully functional HTTP API server, capable of serving spatial queries.
- Spatial Indexing Implementation: A robust spatial index, specifically an R-tree, has been integrated to efficiently store and query UK CodePoint data (postcode, easting, northing coordinates).
- CodePoint Data Loading: The server now loads CodePoint Open data directly from a specified ZIP file at startup, building the spatial index in memory for fast lookups.
- New Search API Endpoint: A new
GET /v1/postcode/searchAPI endpoint has been introduced, allowing clients to query postcodes within a defined bounding box, with built-in validation for search area limits. - Web Server Infrastructure: The Gin web framework has been adopted, along with middleware for Prometheus metrics, health checks, compression, cache control, and CORS, providing a modern and observable API.

Code Review
The pull request introduces a web service for querying postcode data using a spatial index. The architecture is well-structured, but there are issues with error handling and input validation that need to be addressed, especially regarding data parsing.
| err = r.Run(addr) | ||
| log.Fatalf("HTTP API Server failed to start on port %d: %v", port, err) |

Check specifically for http.ErrServerClosed to avoid logging a fatal error during graceful shutdowns. Import "net/http" to use this.
if err := r.Run(addr); err != nil && err != http.ErrServerClosed {
log.Fatalf("HTTP API Server failed on port %d: %v", port, err)
}
