osm2geojson-ultra/dist/output.js

a faster & more complete OSM & Overpass (either in xml or in json formats) to geojson convertor - 4x faster than xmldom + osmtogeojson in most situations - implemented in TypeScript with txml for XML parsing

import { OsmObject } from "./osm-object.js";
export class Output extends OsmObject {
    constructor(type, id, refElems) {
        super(type, id, refElems);
    }
    setGeometry(geometry) {
        this.geometry = geometry;
    }
    toFeature() {
        if (this.geometry) {
            return {
                type: "Feature",
                id: this.getCompositeId(),
                properties: this.getProps(),
                geometry: this.geometry,
            };
        }
    }
}
