Apply a theme

A theme is a colour treatment applied to a style, always a light + dark pair. It is data, not a stylesheet: it rides in the same request as everything else, and it wins over style.

import { Unmap } from "@unmap/sdk";

const unmap = new Unmap({
  key: "um_live_...",
  container: "map",
  theme: "u4e",
  center: [-114.0719, 51.0447],
  zoom: 12,
});

u4e is a short code for a shipped theme preset. The theme builder also exports long ut1. codes for a theme you composed yourself. Both go in the same option.

Maps API covers what a theme may carry.
