Case: Collection field extractor

[gbenadikar]

Add collectionFieldExtractor to extract fields within a collection

import {collectionFieldExtractor, fieldExtractor} from '@quickcase/node-toolkit';

const aCase = {
  id: '1234123412341234',
  state: 'Open',
  data: {
    collection1: [{value: {complex1: { field1: 'value1'}, field2: 'value2'}],
  }
};

// Prepare fields for extraction
const collectionField = fieldExtractor(aCase)('collection1');

// Extract multiple fields from a collection item index
const [field1, field2] = collectionFieldExtractor(collectionField)(0)(['complex1.field1', 'field2']);

// Extract multiple fields from a collection item object
const [field1, field2] = collectionFieldExtractor(collectionField)(collectionItem)(['complex1.field1', 'field2']);

// Extract values for a specific field within a collection
const field2Values = collectionFieldExtractor(collectionField)('field2');

JsonPath already provides flexibility to extract what we need but that will require a lot of string interpolation to be built for the search path e.g. fieldExtractor(aCase)($.${FIELD_1}.${FIELD_2})
