How to store the clustered values into file

[jpnathannew]

I have one question after cluster the values I want to store it in file.
after super cluster object initialize I am getting the following response

Supercluster {
  options: { log: true, radius: 60, extent: 512, maxZoom: 16 },
  trees:
   [ KDBush {
       nodeSize: 64,
       points: [Array],
       ids: [Uint16Array],
       coords: [Float32Array] },
     KDBush {
       nodeSize: 64,
       points: [Array],
       ids: [Uint16Array],
       coords: [Float32Array] },
      points:
   [ { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] },
     { type: 'Feature', properties: [Object], geometry: [Object] } ] }

When I convert and write into a file. Format is changing
I am using Node js. Before writing into file i am JSON.stringify
After that stringify I am getting response like this

{
  "options": {
    "log": true,
    "radius": 60,
    "extent": 512,
    "maxZoom": 16
  },
  "trees": [
    {
      "nodeSize": 64,
      "points": [
        {
          "x": 0.24396358761574075,
          "y": 0.38899943574185264,
          "zoom": null,
          "id": 1,
          "parentId": -1,
          "numPoints": 12,
          "properties": null
        },
        {
          "x": 0.7360923611111111,
          "y": 0.4629351025691785,
          "zoom": null,
          "id": 33,
          "parentId": -1,
          "numPoints": 2,
          "properties": null
        }etc

supercluster name and KDBUSH also missed in that.
Please suggest something

let's say r is the result of your JSON.stringify(...), you can just assign all the properties and serialize trees to KDBush instances. The example uses a worker to index all the points and returns a serialized Supercluster.

        const r = await workerPool.exec('index', [features]);
        if (r?.points && r?.trees) {
          r.trees = r.trees.map((t) =>
            Object.assign(
              new KDBush(
                [],
                () => 0,
                () => 0,
              ),
              t,
            ),
          );
          this.clusterIndex = Object.assign(
            new Supercluster({
              ...(r?.options ?? {}),
            }),
            {
              points: r.points,
              trees: r.trees,
            },
          );
          this.logger.log(
            `Successfully loaded ${features.length} features in ${
              (new Date().valueOf() - start) / 1000
            }s`,
          );
        }
