I agree with you that dynamic query building can be tedious with a pure SQL approach.
The use case you are describing can be solved with something alone the lines of:
WHERE organization = $1
AND ($2 IS NULL OR starts_with(first_name, $2)
AND ($3 IS NULL OR birth_date > $3)
With SQLx you would have all the params to be Options and fill them according the parameters that were sent to your API.
You do not code in the visual environment but it helps you to create tools to visualize exactly what you want/need to see. The interactivity is hard to beat and once you are used to it, you can quickly create visualizations that you can throw away (or keep).
Depending on which model you are interested in, you might find some European company offering the same chassis (usually Clevo or Tongfang).
For example, the Lemur Pro 14 looks like a Clevo L141CU which is also sold by Schenker (or Tuxedo for a Linux version). You can probably find a brand that retails in your area/country/continent.
Following the progress of this project is fascinating.
I don't know how big is the crowd interested in the end goal, the hardware and the software of the Reform. I know for sure that I'm part of that crowd.
The Cowboy looks a bit better to me with its central motor and removable battery but the Vanmoof looks more comfy. The review doesn't mention anything about that.
Is there any other significant difference between the two bikes? If you bought one of those, which criteria were decisive in your decision?
Benedikt Terhechte (from XING and the Contravariance podcast) has a similar project called AwfulUI[1] to bring some SwiftUI goodness on previous iOS releases. I don't think it's open source at the moment though.
With SQLx you would have all the params to be Options and fill them according the parameters that were sent to your API.
Does that make sense?
