TypeSQL is a TypeScript library that parses SQL string literals entirely within TypeScript's type system, providing compile-time type inference, parameter validation, and schema checking without code generation or a database connection. It leverages advanced type-level programming to achieve this, integrating with popular drivers and ORMs like pg, postgres, Kysely, Drizzle, and Prisma, making SQL queries type-safe and ergonomic.
