Hello Simon,
In this talk:

You are validating your fields in the backend. Is there a reason why you choose to do it in the backend? Because I am used to validate fields client side.

Thanks in advance

Do both! Client-side validation helps to provide a good user experience. Server-side validation helps to provide security.

one nice thing about Arrow being multiplatform is that if you put your model and validation in common code, you can actually share it in both front and back-end

Never trust what the client sends! The backend should always verify everything. Attackers do not use your frontend.
