API with NestJS #165. Time intervals with the Drizzle ORM and PostgreSQL

In this article, we explore how to define flexible time intervals in PostgreSQL and communicate effectively with the Drizzle ORM while maintaining data validation.

We emphasize validating input data using ISO 8601 formats in our application to ensure that the users submit correct interval data before adding rows to our database.
