Usage

// Import the HyperGeoJson class
import { HyperGeoJson } from 'hypergeojson'

// Create an instance of the class
const geo = new HyperGeoJson()

// Put a feature in the database
await geo.put({
  "type": "Feature",
  "id": "1",
  "properties": {},
  "geometry": {
    "type": "Point",
    "coordinates": [
      -77.0361328125,
      -11.996338401936226
    ]
  }
})

// Get a feature by its id
const point = await geo.get('1')

// Query points with a quadkey (this is an extremely high-level quadkey)
const stream = geo.quadkeyQuery('2')

stream.on('data', (data) => {
  console.log(data)
})
