Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
This technical article explains how to build vector tiles from scratch to optimize map rendering performance for the NYC Chaos Dashboard. The author describes moving from GeoJSON format to Mapbox Vector Tiles (MVT) to improve loading times by pre-processing data in the backend using Go programming language. The post covers the technical implementation details and benefits of this approach for web mapping applications.

· 4 pulledSince I collect all of the data in one process and return the Dashboard as one HTML file, I kept wondering how I could optimize the map's loading time by pre-processing the data as much as possible in the backend.
This is where vector tiles come in.
The code shown in this post is written in Go.
Initially, all of the map's data was passed to the rendering library in GeoJSON format (embedded directly in the HTML file).
