Mongo‑SQL (aka MoSQL) is a JavaScript library that lets developers build SQL statements by describing them as plain JSON objects. It generates the final SQL string and a parameter list while keeping the query fully inspectable and extensible, so callers can programmatically examine, modify, or add custom helpers for any SQL feature. The package is aimed at Node.js (and browser) developers who need a declarative, value‑oriented way to compose complex queries without imperative chaining.
