JSON File Database for Node.js

node-json-db is a lightweight, file-based database for Node.js, storing data directly in a JSON file. It is currently at stable version 2.6.0 and maintains an active release cadence, with several minor and patch releases occurring monthly or bi-monthly in the past year. Its primary differentiator is the use of a "DataPath" system, akin to XMLPath, for navigating and accessing nested data structures within the JSON file. All operations are asynchronous, leveraging `async/await`. It supports configurable database names, auto-save on push, human-readable file formats, custom separators, and since v2.6.0, serialization of complex JavaScript types like `Set`, `Map`, `Date`, `RegExp`, and `BigInt` via an `ISerializer` contract. This makes it suitable for simple, local data persistence where a full-fledged database system is overkill.
