JSONPath TMF Query

This library aims to provide a simple wrapper around jsonpath, to ease the implementation of TMF630 JSONPath specification as outlined by the TM Forum here

Usage

$3

Accepts a document and an array of query operations to be performed on the document. These operations all take a JSONPath query in the path parameter as outlined here, and have been identified in the TMF630 specification guidelines Part 6. These Operations are outlined below:
1. Sort
2. Filter
3. Fields

Returns a mutated document or collection.

Note: these operations occur in the above mentioned order when combined

$3

#### Sort { path: string, op: 'sort', order: 'asc' | 'desc'}

#### Filter { path: string, op: 'filter', limit?: number, offset?: number}
As filter allows for limit and offset, keep in mind that JSONPath also allows for similar functionality with array slices [x:y]. Combining both will likely return unintended results.

#### Fields { path: string, op: 'fields'}
When Fields is used, the id and href will always be returned. If fields is used on a collection, then the id and href must be included for all elements in the response.

For working examples of JSON Path Querying, look at the [src/test/unit.test.ts]() file from the source repository. These test cases are taken from Part 6 of the TMF 630 specification.
