JSON File Database for Node.js

json-file-database is a lightweight, TypeScript-first file-system-based database designed for Node.js projects that don't require the overhead of a traditional database server. It stores data directly in JSON files, abstracting away the complexities of `fs` and `JSON.parse`/`JSON.stringify` operations. The current stable version is 2.0.3, which introduced breaking changes to allow for a customizable primary key beyond just 'id'. The library differentiates itself by offering pure TypeScript support for fewer type-related errors, debounced writes to minimize disk I/O, and `O(log n)` time complexity for data operations through binary search, making it efficient for small to medium-sized datasets. It's suitable for prototyping, small applications, or configuration management where a simple, local persistence layer is preferred.
