Overview

LazyGraph supports a bespoke path structure for querying a LazyGraph. It has some overlap with

• JSON path (but supports querying a subset of object properties), and

• GraphQL (but it supports direct references to deeply nested properties without preserving structure)/

Example query paths and outputs

“employees” => [{…whole object…, object…]} “employees” => [{ “id”: “3”, “name”: “John Smith, { ”id“: ”4“, ”name“: ”Jane Smith}]} “employees => [{…whole object…, object…]}” “employees => [{…whole object…, object…]}”
