How to calculate gusts: V-max but no U-max?

[noalt]

Hello,

I am playing arround with icon-eu data from dwd for a little project.
Could you share how you calculate the wind gusts?
I can see V-max_10M but no U-max_10M.
Since wind speed is a calculation on both U and V, I don't understand how to use it.

Also, I assume you are using Node.js. Which template engine do you use?
I am thinking of using Dot (for speed), but have no experience with template engines.

Thanks,
