Is it possible to replace the t4-validation?

Hi!

It is totally possible to replace the default ( probably outdated ) validator with something else. We use in production ajv.

With that being said, the validator must validate the (command) object against JSON schemas, which in my opinion is a far better option than JOI taking into account its standardisation cross-language and cross-platfrom support.

Alternatively you could implement completely custom validations in pre-load-conditions ( the validation is basically the same ) and throw validation errors as wish there.

If you decide to go with the JSON schema way, i would be more than happy to provide you with an example that uses custom validator.

@nanov I'm not limited to Joi and would highly appreciate your ajv-example.

I am on it.

Ok,

I've tried to come up with something quickly.
I will continue to update those examples when I find the time as i truly believe those are useful.

As per your specific question :

Complete AJV validation and error reporting is implemented in this example. Take a look at it and how it works, and let me know if this is helpful.

Thanks, that's definately helpful! I'll play around with it.
