How can I validate inputs in GraphQL?
You can validate inputs in GraphQL by using custom scalar types, middleware, or validation libraries like Joi.
Can you give me an example of using Joi for validation?
Sure! You can define a schema with Joi and use it in your resolver to validate the input before processing.
What if the input is invalid?
If the input is invalid, you can throw an error in your resolver, which will be returned to the client.
Are there any built-in validation features in GraphQL?
GraphQL itself doesn't have built-in validation, but you can implement it using directives or custom logic.
