Honeycomb

A set of functions to construct/tweak a filter mask for API response.

Filter mask

A filter mask is a JSON object which provides the minimal structure of another JSON object, typically an API response. It provides all the possible keys in an object, and the general structure of all the objects inside an array.

Examples

For the following JSON:

{
  results: [
    {
      "foo": 1
    },
    {
      "bar": 2,
      "barz": 3
    }
  ],
  "status": 200
}

The mask for it would be:

{
  results: [
    {
      "foo": true,
      "bar": true,
      "barz": true
    }
  ],
  "status": true
}

Installation

npm install honeycomb

In Node.js:

const Honeycomb = require('honeycomb');

In browser, add the script tag to honeycomb.js and the Honeycomb object will be available in the window object.

Usage

const honeycomb = new Honeycomb();

const api = {
  results: [
    {
      "foo": 1
    },
    {
      "bar": 2,
      "barz": 3
    }
  ],
  "status": 200
};

const mask = honeycomb.parse(api);
console.log(mask); 
// {"results":[{"foo":true,"bar":true,"barz":true}],"status":true}

API

parse/1

Parses the input into a mask.

toTree/2

Constructs a tree object from a mask. This tree can be passed into libraries such as jstree. Besides taking a mask as the first param, it can also take an optional callback function for each node in tree.
