Hi, author here. I talked about this in more length here https://leontrolski.github.io/dom-syntax.html and to some extent here https://leontrolski.github.io/33-line-react-thoughts.html . There was also some

To clarify, the non-trivial thing I'm building is more for exploring the "unified templating language for backend and frontend" bit. I want to be able to use the same code to: - render entire pages from a Python backend - use

Author here, thanks for the feedback. This is v. much a work-in-progress, I'm in the process of trying to build something non-trivial with it. Just a couple of things to address in general from the comments so far: - I'm aware o

Author here, nice to see this got some interest! As a very small benchmark (uh-oh!), in a console on the linked page, I tried to make/recreate 10,000 divs: const root = document.getElementById('noughts') m.render(root,

Using m or h as VDOM constructors are mithril/hyperscript-isms, I guess that's not obvious if you not worked with those or similar libraries, sorry!

Author here - I did put a warning in guys :-) Lots of the code looks pretty code-golfy - I promise I don't do stuff like this at work, neither should you Happy to s/g/grid/ - writing the whole exercise felt a bit

Mithril's approach (as robertakarobin refers to) is that diffing VDOMs is cheap (where as updating the DOM itself is expensive), the "library" in this post takes the same approach. It's interesting, there's a lot of

My feeling is that if html and js had syntactically shared data structures at their conception, we wouldn't have quite so much frontend mess as we do now and declarative UI would have been the norm for a while. Having said that, I&#x

Yeah, it's very mithril influenced (I love that library) - I namecheck them in the article at the top.

Great answer, thanks! Embarrasingly, I didn't even know about className :-)

In what way would you say the event binding here differs from React's? (Genuinely interested). The main difference from where I'm sitting is that React has a concept of "Component state" - updates to which trigger local

Agreed, let me know if you find a better way! I feel if the browser APIs were slightly more declaratively inclined, this article could be "10 line React".

I'm not sure if any of their content is still relevant, but mithril makes some bold claims for >React performance: https://mithril.js.org/framework-comparison.html#react "Generally speaking, React's approa

I'm not sure I can quite express what I'm thinking, but do you think this could be achieved orthoganally to the rendering library itself? (Just by "normal" js).

by leontrolski 7y ago
Author here, this was written as a way for me to explore the core idea of react in a minimal setting. Things it's missing - jsx - routing - performance (maybe?) - component state management stuff What else would you include?
