Ergonomic constructors for QueryFilterExpression. Every helper returns plain data, so a filter can equally be written as an object literal, stored as JSON, or produced by the experimental semantic builder.

Example

import { envelope, queryFilter } from "@honua/sdk-js";

const filter = queryFilter.and(
  queryFilter.eq("STATUS", "open"),
  queryFilter.gt("SEVERITY", 3),
  queryFilter.spatial("intersects", envelope(-158.5, 21.2, -157.6, 21.7)),
);
