lowdb is a tiny, type-safe local JSON database for Node.js, Electron, and the browser. Data is stored as a plain JavaScript object in a JSON file, manipulated with native JavaScript, and persisted with safe atomic writes.

Use cases

• store app settings in a json file
• simple local database for a small node app
• persist data in an electron app without a server
• embed a lightweight json datastore in a browser app
• save user data to db.json with typescript type safety
• swap a full database for a flat file in prototypes

When to choose

• you need simple, dependency-light persistence for small datasets
• you want data as plain JavaScript objects with no query language
• you're building Electron, Node, or browser apps with local JSON storage
• you want hackable storage adapters (YAML, encryption, etc.)

When to avoid

• you need concurrent writes from multiple processes or servers
• you need querying, indexing, or large datasets beyond memory
• you need relational or transactional guarantees
