A procedural star system generator based on 21st century exoplanet research
API docs (unfortunately not very good due to TypeDoc being immature)
Example:
// yarn add stellardream
import { StarSystem } from 'stellardream';
const starSystem = new StarSystem(1549748672440);
console.log(JSON.stringify(starSystem, null, 2));Output:
