JSONPath (@skyleague/jsonpath)

JSONPath is a syntax for specifying locations in a JSON document. It allows you to specify a path to a value within the document, using a set of rules and conventions.

Engine

This library adds a type layer on top of an existing jsonpath engine: jsonpath-plus. Having full type inference in JSONPath can be useful because it allows the package to automatically determine the types of the values that are being accessed and manipulated with JSONPath. This can make it easier to use the package, as you don't have to manually specify the types of the values that you are working with.

For example, consider the following JSON object:

const person = {
  "name": "John Smith",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "state": "NY"
  }
}

With full type inference, you can use JSONPath to access and manipulate the data without needing to manually specify the types of the values. For example, you can use the JSONPath.get(person, "$.name") path to access the name property, which has a type of string, and you can use the JSONPath.get(person, "$.age") path to access the age property, which has a type of number.

Example

import { JSONPath } from '@skyleague/jsonpath'

const object = {
    store: {
        bicycle: {
            color: 'red',
            price: 19.95,
        },
        book: [
            {
                category: 'reference',
                author: 'Nigel Rees',
                title: 'Sayings of the Century',
                price: 8.95,
            },
            {
                category: 'fiction',
                author: 'Evelyn Waugh',

        ],
