But Svelte obviously doesn't play well with TypeScript, and is kind of its own language - you don't need a source for that. Good luck e.g. getting reactive declarations to play well with TS's type narrowing or null analysis.

you clearly don't know what you are talking about. reactive declarations do not change the type of the objects. it just that they can rerun when the dependencies change. sure for the convenience of the users you do not need to type `let vars...` for every new variable declared in the reactive statement, but no one forbid you to write it before hand, or let the language server/plugin do it for you. but Svelte indeed d…

Data-point of one, but I have definitely run into issues where Typescript can't understand what's going on in a reactive expression, and had to aggressively refactor my code to make everything happy. Most of the time it works great, but when it doesn't it can be really annoying. I wouldn't go so far as to say it doesn't play well, but the seams are definitely visible.

I'm curious what peoples' experiences have been using modern react vs svelte vs whatever else is popular these days. I used react a while back for a dashboard mockup and was pretty happy with it. Something about svelte being a superset of standard html/js/css that gets compiled bothers me. I realize that the same can be said about typescript/tsx but I feel like in can trust it more... Maybe it's a maturity thing? Or…

Svelte is a better experience IMO. Faster and doesn't require manual hacks to gain a 0.005% speed improvement.

If it's only a 0.005% speed improvement the manual hacks probably aren't required :P

I don't use Svelte in my day-to-day (I use React) but I love reading about it and others in the space. We need new ideas and other packages are really pushing us forward!

I remember when I was talking about some code my team wrote once and we'd managed to get an operation down from 6 hours to like 5 minutes.

Another manager said to me (fairly with hindsight) "If you get something down from two hours to one hour, that's an opimisation. Going from 6 hours to 5 minutes means it just wasn't finished."

you can download a html page from some website, rename it to `.svelte` and it will mostly work just fine with some minor modifications like remove the html wrapper tag and rename `` to ``.

I don't think the same thing apply for any other popular frontend frameworks.

I love Svelte because prototyping a new feature in it is really really trivial, even with keyboard interactions and animation effects.

Finishing a project is one hell of an optimization, I suppose!

Could someone give a one or two sentence explanation of why I would want to use Svelte over something like React? I have heard it is "better", but have never understood why.

JS frameworks are like coffee, some people like them milky and full of sugar, some people like them like them lean and black, some are obsessed with making the "worlds best coffee" at home every morning, and some drink whatever brown water comes out of a vending machine. We all like our coffee different, just as we all have favourite features and designs of frameworks. There is no correct, or best, framework, only pe…

Thank you ChatGPT

@dang https://news.ycombinator.com/item?id=36432447 was on the front page and has substantially more discussion. It was somehow marked as a duplicate of this post. Could you merge them?

I emailed the mods. I don't think they get notified for @'s.

Could be the plugin was broken somehow. Happen all the time for me. Even now the syntax highlighting and code formatting feature would break if I write the code the wrong way.

from my understanding the plugin does some clever tricks like insert some dummy code or create some dummy files to be consumed by the typescript language server. so it is not guaranteed to be correct 100% of the time.

fun/weird fact - the major release seems to have caused ~9m downloads happening on npm, catapulting Svelte to technically the top of the charts https://twitter.com/SvelteSociety/status/1671923994671603713...
