Orma is a pure‑JavaScript library that lets developers write type‑safe, JSON‑serialisable queries and mutations which are automatically compiled into efficient, batched SQL for MySQL, PostgreSQL and SQLite. It’s aimed at TypeScript/JavaScript backend developers who want a declarative, validation‑friendly way to fetch, update and create relational data—complete with features like multitenancy, schema introspection, and automatic diff‑based mutation generation.
