Developers prototyping small Node.js projects often face a dilemma: SQLite requires too much boilerplate, MongoDB feels like overkill, and plain JSON files lack security. SnapJSON addresses this gap as an open-source library that turns JSON files into a lightweight ORM with zero configuration. It provides a developer-friendly interface for data storage without server setup.

SnapJSON includes built-in encryption using AES-256-GCM, securing local files automatically. It also handles collection relations, allowing developers to define and query relationships between data sets without manual loops or filters. The library is installed via npm and requires no database servers, Docker containers, or complex connection strings, streamlining the development workflow for small-scale applications.

The tool targets prototyping, CLI tools, and small apps where a full database engine is unnecessary. Its creator is actively seeking feedback from early adopters to refine the API, particularly around relationship handling. As an open-source project, SnapJSON aims to simplify data persistence for developers who need structure without the overhead of traditional databases.
