Mapbox Vector Tile Protobuf Serializer

vt-pbf is a JavaScript library for serializing Mapbox vector tiles into binary Protobuf format, adhering to the Mapbox Vector Tile Specification. It provides methods to convert both `vector-tile-js` objects and `geojson-vt` tile structures into a Protobuf buffer. The current stable version is 3.1.3. Releases appear to be driven by bug fixes and performance improvements, with a focus on specification compliance and encoding correctness for various GeoJSON types and property values, as seen with recent fixes for `null` value encoding. Its primary differentiator is its direct integration with Mapbox's ecosystem libraries like `geojson-vt` and `@mapbox/vector-tile` for efficient tile generation and manipulation, rather than being a generic Protobuf library.
