validation

You validate API request bodies by checking the incoming JSON data against predefined JSON Schema definitions using the AJV library. This ensures deterministic data integrity and consistent error reporting before processing inputs.

The best way to enforce data contracts is by defining reusable JSON Schemas for your data entities. Validating service inputs against these schemas prevents invalid database inputs and maintains application-wide data integrity.

Yes, you can generate TypeScript types directly from your JSON Schema definitions. This allows you to enforce strict data contracts and maintain type safety from the API validation layer through to your application logic.

Yes, AJV works for validating form submissions and API query parameters. It checks submitted data formats, such as email structure and password strength, against your schema rules to ensure required fields are present and correct.

Inconsistent validation errors often occur when schemas are not strictly enforced. Using the AJV library to validate data against structured JSON Schema definitions provides deterministic, consistent error reporting for missing or invalid fields.

You need JSON Schema validation when accepting external data inputs, such as new user registrations via an API. It verifies that submitted email formats, password strength, and required fields conform to predefined rules before processing.
