This is a
playground to test code. It runs a full
Node.js environment and already has all of
npm’s 400,000 packages pre-installed, including
gdalmultitosingle with all
npm packages installed. Try it out:

Transform multi-part geometries to single part geometries.
npm install gdalmultitosingle
const gdalMultiToSingle = require('gdalmultitosingle') const outputPath = gdalMultiToSingle.processData(<inputFeatures>, <outputName>, <outputFormat>); // Returns the output filepath.
const gdalMultiToSingle = require('gdalmultitosingle'); const gdal = require('gdal'); const getFeatures = dataset => gdal.open(dataset).layers.get(0); const inputLayer = getFeatures('path/to/inputData.geojson'); const singleParts = gdalMultiToSingle.processData(inputLayer, 'path/to/outputData.shp', 'ESRI Shapefile');
Tested with the most common outputs that are listed on gdal. Message me on GitHub if you need some help or find some bug.
You can also use vsimem to save the data temporary on the memory. So the command would be something like:
const singleParts = gdalMultiToSingle.processData(inputLayer, '/vsimem/temp_output.shp', 'ESRI Shapefile')
