bookshelf-postgis
Bookshelf plugin for PostGIS to automatically parse and serialize geometry/geography columns on fetch and save, respectively. Geography columns are parsed to specified attributes (e.g. [lon, lat]
results in a lon
and a lat
attribute on the model), and geometry columns are parsed to GeoJSON.
NOTE: Geography columns must already be WGS 84 lon lat (SRID:4326)!
Installation
npm install bookshelf-postgis --save
Usage
Apply the plugin:
const postgis = require('bookshelf-postgis');
bookshelf.plugin(postgis);
And add geography
or geometry
columns to your model:
const User = bookshelf.Model.extend({
tableName: 'users',
geography: {
location: ['lon', 'lat'],
// Use dot notation to specify deeper nesting
geo: ['address.lon', 'address.lat'],
geo2: ['location[0]', 'location[1]'],
},
geometry: ['geometry']
});
