I'm using karax to rebuild a site which displays charts and metrics. It is going well and should be deployed in the next 2 months. The site is not public, unfortunately.
Before this it was Go templates and vanilla js.
I created my personal website with Nim, although it's very simple:
The site I mentioned above is live (but still only internal). I used Jester as well. It has been a pleasure working on this project and I really appreciate the Nim community.
So far the feedback from the users has been positive. I had one person ask me how the charts load so fast :). And this is with MariaDB. Initial testing with the analytics database DuckDB yeilds 10-100x speed ups.
Maybe this is obvious, but it is also very possible and not too difficult to create something only with the std libs as well if you want something really lightweight and don't want/need httpbeast. For backend Scorper is also nice.
I don't think this would be of anyone interest, but recently we published a website which I built with Jester + Karax for server side templating. It's up at https://covidphy.eu.
It has a bit of JS that is also compiled from Nim code.
The site is deployed in a tiny VPS behind Nginx (shared with a handful of other tiny sites), so I hope it doesn't collapse.
The choice of Nim over Python was that at a couple of points I have to interface with Mafft, which is straightforward with Nim. Reviewers were impressed with the overall speed of the site, quickest paper I've ever published.
Code is available if you're curious enough.
