  1. Create reusable functions for validation and casting: One of the most effective ways to minimize redundant code is by creating reusable functions for validation and casting. Hapi and Joi allow you to define custom validation and casting functions that can be reused across routes and endpoints.

  2. Use middleware for common validation and casting tasks: Hapi allows you to define middleware that can be executed before or after a route handler. You can use middleware to handle common validation and casting tasks such as checking for the presence of certain headers, parsing query parameters, or casting payload to a specific data type.

  3. Define validation and casting schemas: Joi provides a powerful schema definition language that can be used to define validation and casting rules for various types of data. You can define schemas for input data, request payloads, and responses, and reuse them across your application.

  4. Use grouping and composition to organize validation and casting logic: Hapi allows you to group routes and endpoints based on specific criteria such as authentication requirements or resource type. You can use this feature to organize your validation and casting logic into reusable modules or plugins that can be shared across different parts of your application.

  5. Use error handling middleware to handle validation and casting errors: Hapi provides error handling middleware that can be used to handle validation and casting errors in a consistent manner. You can define custom error messages and error codes for different types of validation errors and handle them using a centralized error handling middleware.
