Reachable range service NodeJS

Areas reachable from a geocoded address within a drive time and a distance, summarised by a Node.js process

import { type BBox, budgetUnits, TomTomConfig } from '@tomtom-org/maps-sdk/core';
import { calculateReachableRanges, geocodeOne } from '@tomtom-org/maps-sdk/services';
import { API_KEY } from './config';

TomTomConfig.instance.put({ apiKey: API_KEY });

const formatBBox = (bbox: BBox) => bbox.map((value) => value.toFixed(3)).join(', ');

(async () => {
    const origin = await geocodeOne('Domplein 9, Utrecht');
    console.log(`Origin: ${origin.properties.address.freeformAddress}\n`);

    const ranges = await calculateReachableRanges([
        { origin, budget: { type: 'timeMinutes', value: 30 } },
        { origin, budget: { type: 'distanceKM', value: 25 } },
    ]);

    for (const range of ranges.features) {
        const { budget } = range.properties;
        const vertices = range.geometry.coordinates.flat(1).length;
        console.log(
            `${budget.value} ${budgetUnits[budget.type]}: ${vertices} vertices, bbox [${formatBBox(range.bbox)}]`,
        );
    }

    if (ranges.bbox) console.log(`\nBoth ranges fit in [${formatBBox(ranges.bbox)}]`);
})();

An address is geocoded, and the areas reachable from it within a drive time and within a distance print as a vertex count and a bounding box each.

geocodeOne returns a place that calculateReachableRanges takes as its origin unchanged.
calculateReachableRanges answers each budget with a GeoJSON polygon whose properties echo the request, so its budget labels the line through budgetUnits.
Each polygon, and the collection, arrives with its bbox already computed, so nothing walks the vertices to find it.
