Through an HTTP request, I receive from client side the following body:
{
a: string,
b: string,
c: string
}
I want to validate them with joi, so I do:
const MySchema = Joi.Object<MyModel>().keys({
a: Joi.string().alfanum().min(1).max(150).optional(),
b: Joi.string().alfanum().min(1).max(150).optional(),
c: Joi.string().alfanum().min(1).max(150).optional(),
}).required()
This allows empy objects.
How can I say to joi to not allow empty object? I want the body request to have at least one of those keys. For now I haven't found the solution.
I know that I can handle it in the API but I don't want to write useless code.
Thank you!
I solved it with
Joi.object<MyModel>.keys({/*My keys*/}).required().min(1)
