    dbgeo

    Convert database query results to GeoJSON or TopoJSON. Inspired by Bryan McBride's PHP-Database-GeoJSON. Works with your database of choice - ideally paired with node-mysql, node-postgres, or mongodb. It is a more flexible version of postgeo and mysql2geojson (both deprecated).

    Installation
    npm install dbgeo
    
    Example Usage
    var dbgeo = require('dbgeo')
     
    // Query a database...
     
    dbgeo.parse(data, {
      outputFormat: 'geojson'
    }, function(error, result) {
      // This will log a valid GeoJSON FeatureCollection
      console.log(result)  
    });
     

    See test/test.js for more examples.
