Important: I am utilizing the Cordova plugin.
polygon: Point[];
interface Point {
x: number;
y: number;

Shawn brought up an interesting point about SQLite's recent implementation of its own GeoPoly type - you can read more about it at
However, the most "correct" approach would likely involve utilizing one of the various GIS standards available. Both GeoJSON and WKT are suitable for storing polygons easily in a text field. Alternatively, if you prefer binary data, there's WKB which can be stored in a blob field (refer to the WKT link for further information).
There exist plenty of tools in different programming languages that facilitate the conversion and handling of these data types.
It is worth mentioning that utilizing GeoPoly in SQLite provides basic spatial capabilities, while GeoJSON and WKT do not. If advanced spatial capabilities are desired, you might want to explore using spatialite instead.
