About kysely
Kysely is a type safe TypeScript SQL query builder for Node.js, Deno, Bun, and the browser. It provides a fluent API to construct and execute type safe SQL queries, preventing runtime errors from invalid column names or incorrect data types. The core problem it solves is eliminating the fragility of raw SQL strings and the lack of type safety in many ORMs within the TypeScript ecosystem.
