I didn't remember this being too bad. I just checked with Elm 0.17 using the tutorial's [1] nesting/3-gif-pair.elm as the main. Size is 209k out of elm-make, 60k minified (closure compiler advanced), and 19k gzipped. I wouldn't use it for validating a form field but the size seems completely reasonable for a language runtime.

What people are saying
I imagine building this was a useful learning experience (and your intro blog post alludes to that), but keep in mind that Redux is much more a way of thinking about state…

Read the project’s introduction
Elm
Elm is a programming language that compiles to JavaScript. It is known for its friendly error messages, helping you find issues quickly and refactor large projects with confidence. Elm is also very fast and very small when compared with React, Angular, Ember, etc.
This repo focuses on The Elm Architecture, an architecture pattern you see in all Elm programs. It has influenced projects like Redux that borrow core concepts but add many JS-focused ideas.
The Elm Architecture
The Elm Architecture is a simple pattern for architecting webapps. The core idea is that your code is built around a Model of your application state, a way to update your model, and a way to view your model.
To learn more about this, read the the official guide and check out this section which is all about The Elm Architecture. This repo is a collection of all the examples in that section, so you can follow along and compile things on your computer as you read through.
Run The Examples
After you install, run the following commands in your terminal to download this repo and start a server that compiles Elm for you:
git clone https://github.com/evancz/elm-architecture-tutorial.git
cd elm-architecture-tutorial
elm reactor
Now go to http://localhost:8000/ and start looking at the examples/ directory. When you edit an Elm file, just refresh the corresponding page in your browser and it will recompile!

4 sourcesPlease correct me if I'm wrong, but I think the approach of your final paragraph could be very straightforward to implement in Elm (a purely functional language that also has one of the best implementations of FRP that you can find anywhere, in any language). See this article on "the Elm architecture", which I think could be very naturally extended in the way you propose:
https://github.com/evancz/elm-architecture-tutorial
Elm's approach involves having completely declarative, purely functional UI code (with efficient update computations resolved via a virtual DOM in the background), where individual components are highly composable and referentially transparent.
In Rage Against the Finite-State MachinesI agree that some points are actually valid (conceptually).
However React permits to do useful compromises on purity for practicity.
In Elm you have to hack the system to give the focus to a single input or use an external lib... See https://github.com/evancz/elm-architecture-tutorial/issues/4...
In Why React/Redux is inferior as a paradigmOne of the things I found odd (or maybe just annoying) is how the Elm Architecture doc [1] keeps mentioning how you can cleanly model your code using modules. But the module system is about as primitive as you could imagine. The language would be much more expressive with ML's module system, and functors would relieve some of the pain of not having type classes.
