Abreviates GeoJSON keys like properties, geometry, coordinates to minimize the overhead. Is really slow for large files due to the recursive function and fails if there are already properties like: 't','g','p', 'c','f'
For a large FeatureCollection of 3,5MB (ca. 10.000 features), the compressed Collection had about 2,8MB.
npm install compress-geojson
var compressGeojson = require('compress-geojson');
var compressed = compressGeojson.compress(geojsonFeature);
var decompressed = compressGeojson.decompress(compressed);
