[Umap + geoJSON] How to add "umap", "layers", and "_storage"?

Hello,

This code in Python…

import re,sys
import geojson
from geojson import LineString, Point, Feature, FeatureCollection, dump

props = {"name": "Some name", "description": "Some description", "_storage_options": {"color": "MediumVioletRed"}}
linestring = LineString([(2.390588521957398, 48.85313149149458), (2.3488533496856694, 48.87182151098106)])
features = []
features.append(Feature(properties=props,geometry=linestring))
feature_collection = FeatureCollection(features)

with open('myfile.geojson', 'w') as f:
   dump(feature_collection, f, indent=2)

… outputs this:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "LineString",
        "coordinates": [
          [
            2.390588521957398,
            48.85313149149458
          ],
          [
            2.3488533496856694,
            48.87182151098106
          ]
        ]
      },
      "properties": {
        "name": "Some name",
        "description": "Some description",
        "_storage_options": {
          "color": "MediumVioletRed"
        }
      }
    }
  ]
}

However, to import a full map into Umap, it needs a bit more before and after:

{
  "type": "umap",
  "properties": {
    "easing": true,
    "tilelayer": {
      "name": "OSM Sunny (jawgmaps)"
    },
    "licence": ""
  },
  "geometry": {
    "type": "Point",
    "coordinates": [
      2.2780323028564458,
      48.802962875092014
    ]
  },
  "layers": [
    {
      "type": "FeatureCollection",
      "features": [
        {
          "type": "Feature",
          "properties": {
            "name": "blah",
            "description": "blah"
          },
          "geometry": {
            "type": "LineString",
            "coordinates": [
              [
                2.3110949921647266,
                48.81514649393979
              ],
              [
                2.2819232977235515,
                48.84809311844251
              ]
            ]
          }
        }
      ],
      "_storage": {
        "displayOnLoad": true,
        "browsable": true
      }
    }
  ]
}

, ie. “type=umap”, “layers”, and “_storage”.

Does someone know how to add those using geojson, and come up with a full file ready to build a new map from scratch?

Thank you.

I also notice that even if I set “displayOnLoad” to “false” when importing a geojson file, all the layers are displayed:

"_storage": {
  "displayOnLoad": false,
  "browsable": true,
  "remoteData": {},
  "name": "Layer 1"

What is the right way to tell Umap to hide all the layers when importing them, or hide them all in one go manually?

Thank you.
