Package Exports

json-columnar-compression
json-columnar-compression/dist/index.js
json-columnar-compression/dist/index.mjs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-columnar-compression) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Json to Columnar Compression

Efficiently converts JSON to columnar format and back, enabling faster transmission and reduced storage.
This approach is especially beneficial when working with large datasets .
You can provide JSON in any structure or format.

import {CompressJsonToColumnar , DecompressColumnarToJson} from 'json-columnar-compression'




const array = [
  {
    "id": 1,
    "name": "Alice",
    "age": 28,
    "city": "New York",
    "children": [
      { "id": 11, "name": "Anna", "age": 5 },
      { "id": 12, "name": "Alex", "age": 7 }
    ]
  },
  {

  },
  { "id": 3, "name": "Charlie", "age": 25, "city": "Chicago", "children": null }
]



const compressed = CompressJsonToColumnar(array)

// console.log(compressed)
// [
//   ["id", [1, 2, 3]],
//   ["name", ["Alice", "Bob", "Charlie"]],
//   ["age", [28, 34, 25]],

//     ]
//   ]
// ]


const decompressed = DecompressColumnarToJson(compressed)

// console.log(decompressed)
