TrivialDB is a tiny, in‑process key/value store that persists data as plain JSON files. It wraps vanilla JavaScript objects with a lodash‑style API, offering both synchronous “dirty” operations and promise‑based safe reads/writes, and can run in Node or in the browser (using REST, IndexedDB or LocalStorage). It’s aimed at developers who need fast, simple persistence for small‑to‑moderate data sets such as blogs, configs, session stores, or static‑site data without the overhead of a full database.
