H3Decoder

H3Decoder is the lightweight H3 geometry adapter exported by @math.gl/dggs/h3. It accepts hexadecimal H3 strings and bigint indexes, and implements the common DGGSDecoder center, boundary, bounds, and token/index conversion methods.

For traversal, neighborhood, fill, compaction, metrics, and other H3 operations, use the full h3-js API directly.
