Input Parameters

• data (GeoJSON FeatureCollection)
  • This parameter represents the GeoJSON data that needs to be converted. The data should be a valid GeoJSON object following the FeatureCollection format.
  • Example of a valid FeatureCollection:

    const geojsonData = {
      type: 'FeatureCollection',
      features: [
        {
          type: 'Feature',
          geometry: {
            type: 'Point',
            coordinates: [102.0, 0.5],
          },
          properties: {
            name: 'Sample Point',
          },
        },
        {
          type: 'Feature',
          geometry: {
            type: 'Polygon',
            coordinates: [
              [
                [102.0, 0.0],
                [103.0, 0.0],
                [103.0, 1.0],
                [102.0, 1.0],
                [102.0, 0.0],
              ],
            ],
          },
          properties: {
            name: 'Sample Polygon',
          },
        },
      ],
    };

• options (ConvertOptions)
  • This is an optional object that allows you to specify the output format and filename.
  • Properties:
    • format (string): The desired output format. Can be one of the following values:
      • 'geojson'
      • 'shapefile'
      • 'kml'
      • 'gpx'
      • 'csv'
    • filename (string): The name of the output file. Default is 'data'.
  • Example of ConvertOptions:

    const options = {
      format: 'shapefile', // Converts the GeoJSON data to Shapefile
      filename: 'shapefile_output',
    };

Usage

import { useGeoConvertToFile } from '@hungpvq/shared-file';

const { convert } = useGeoConvertToFile();

// Convert GeoJSON to Shapefile
const geojsonData = {
  type: 'FeatureCollection',
  features: [
    /* your features here */
  ],
};

const blob = await convert(geojsonData, { format: 'shapefile' });

// Convert GeoJSON to KML
const kmlBlob = await convert(geojsonData, { format: 'kml' });

// Convert GeoJSON to CSV
const csvBlob = await convert(geojsonData, { format: 'csv' });
