Hasura has introduced a new feature called Input Validation Permissions, aimed at enhancing data integrity and security in application development. By allowing developers to implement custom data validation logic for GraphQL mutations, this feature acts as a pre-mutation hook, ensuring that only valid data is processed and stored in the database. Input Validations can address various use cases such as user registration and authentication, managing user-generated content, and enforcing restrictions on allowing requests. This powerful tool helps developers build more reliable and secure applications by giving them control over the entire validation process.
