Karax is a framework for developing single page applications in Nim. It's still in heavy development, so keep in mind that the API is subject to change.

To try it out, run:

nimble install # For first time

cd examples/todoapp
nim js todoapp.nim
open todoapp.html
cd ../..

cd examples/mediaplayer
nim js playerapp.nim
open playerapp.html

It uses a virtual DOM like React, but is much smaller than the existing frameworks plus of course it's written in Nim for Nim. No external dependencies! And thanks to Nim's whole program optimization only what is used ends up in the generated JavaScript code. But don't take my word for it, look at this:

• Leverage Nim's macro system to produce a framework that allows for the development of applications that are boilerplate free.
• Keep it small, keep it fast, keep it flexible.
