lowdb Local JSON Database

lowdb is a lightweight, type-safe, local JSON database designed for Node.js, Electron, and browser environments. The current stable version is 7.0.1, with a frequent release cadence that has seen multiple major and minor versions released recently, indicating active development and continuous improvement. Key differentiators include its minimalist API for interacting with data using native JavaScript array methods, robust TypeScript support for data schema, and a highly extensible architecture via 'adapters'. These adapters allow for custom storage solutions (e.g., YAML, JSON5, encryption) and seamless integration across different environments (file system for Node, localStorage or sessionStorage for browsers). It is primarily an ESM-first package, simplifying usage in modern JavaScript projects but requiring specific import patterns. It also offers convenient presets for common use cases like JSON files and browser storage, alongside automatic in-memory mode for testing.
