The article discusses the benefits of using sqlx-ts, a CLI application that provides compile-time checked queries and generates types against SQLs to ensure type safety in TypeScript and Node.js projects. Unlike traditional ORMs, sqlx-ts does not rely on a DSL for query building. Instead, it uses regular SQL queries and connects to the local or development database at compile-time to verify the queries and generate types based on the information_schema. This approach offers several advantages, including improved type safety, reduced runtime errors, and better performance. Developers can install sqlx-ts as an npm module or as a separate binary. The article provides step-by-step instructions for installation and usage in TypeScript and Babel-based projects. Overall, sqlx-ts is a powerful tool for developers who prioritize type safety and want to enhance their experience with SQL in TypeScript and Node.js.
