Advanced Type Checks with Zod

Get a solid understanding of how to leverage Zod to enhance runtime data validation in JavaScript or TypeScript applications

You will learn how to create and manage complex, nested schemas using a real world example (room bookings with guest details) used throughout all lessons. All created schemas are tested against potential bugs and we verify error messages.

The course covers topics such as:

  • Utilizing Zod's shape and unwrap features to perform partial validations without losing the overall schema structure.
  • Managing optional, nullable and nullish properties.
  • Implementing unions and intersections to handle different types of data.
  • Ensuring type safety with sets and maps, including custom validation logic for primitive values.
  • Creating custom error messages for improved user feedback.
