Http4s VS hn-search

http4s is a Typelevel project, and therefore falls into the "program in Scala as if it were Haskell" category. Many people find this off-putting, but honestly, I think with the resources listed above, this is the option at the best intersection of "mature" and "well-documented" available in Scala. The reason it's off-putting to many people is that Haskell-style pure FP isn't mainstream, so it isn't so much a matter of learning a new technology as it is a matter of learning a new paradigm, which necessarily means surfacing and unlearning things you already know, and perhaps confronting the uncomfortable feeling that things you thought were "fundamental," "have to be that way," aren't, and don't. I personally found this process liberating. But not everyone does.

If you want a mature REST API library, I recommend http4s. Be aware, though, that it’s based on purely-functional programming with Cats, cats-effect, and fs2, so if you’re not familiar with them or aren’t prepared to commit to the paradigm, the learning curve may be daunting, seem pointless, or both.

See also cats-effect and fs2. cats-effect gives you your IO Monad (and IOApp to run it with on supported platforms). fs2 is the ecosystem’s streaming library, which is much more pervasive in functional Scala than in Haskell. For example, http4s and Doobie are both based on fs2.

Most important/known: * https://http4s.org/ - an HTTP client/server * https://github.com/typelevel/fs2 - streaming * https://github.com/tpolecat/doobie - JDBC

Scala devs are too busy wondering about free monads and F[Request[F] => Response[F]]. I am very pleased by http4s, Doobie, ScalaJS, and the whole ecosystem, really: https://http4s.org

In reality, your performance issues will not be http4s, but something else. That being said, there are improvements that http4s can and is making, and I'm quite excited about the future 1.0 release, which has some important and fundamental performance improvements already, like a a 125% performance improvement on the plaintext benchmark from https://github.com/http4s/http4s/pull/6091 - and finally, yes, akka-http does have very good performance, but you can also get good performance out of http4s.

http4s for REST services.

This is a long list of misunderstandings I don’t have the patience to unpack. Instead, let me refer you to the links in my top comment in the thread, then suggest you learn at least http4s, a purely-functional web service library that’s been used in production for a decade or so now.

The most popular nowadays are - I guess - akka-http and http4s. You can also use Play if you don't want to start from scratch but prefer a framework-based approach.

There are functional frameworks: https://http4s.org/

Submitters: If you want to say what you think is important about an article, that's fine, but do it by adding a comment to the thread. Then your view will be on a level playing field with everyone else's: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...

I'm a huge Tesla skeptic, but Tesla and Musk are lightning rods for tabloid-style garbage that doesn't belong on HN, so it doesn't surprise me that we often see negative Tesla content flagged to death. Meanwhile we also see plenty of content that hits the front page and stays there [0].

Do you have examples of professional, interesting Tesla content that got flagged?

It's April 23rd, 2024, and I am still looking for a good, reliable, honest and simple search engine.

All I want to do is search.

No AI.

No ads.

No shopping.

Please don't "Answer my question." I enjoy doing my own original research, thanks.

I'm entirely willing - wanting even - to pay for it.

Currently Kagi has my $, but I'm saddened and frustrated that they're not even focused on Search, they're focused on AI[1] and t-shirts.

Amazingly, in 2024, there is still a market opportunity for a good search engine.

It can't really just be me, can it?

For historical purposes

Most likely because there have been oodles of low-quality stories on these topics. We turned the flags off on this one since it maybe rises above the noise (see https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so... for past explanations on how we approach that).

Hey HN,

I'm sure you've seen the monthly "Ask HN: What Are You Working On?" headlines on [Hacker News](https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...).

Honestly, it's my favorite topic because it's packed with insights about what other hackers are up to.

I wondered what it would be like if instead of just a headline, there was a whole website where hackers could post daily updates, and where we could follow the hackers we're interested in for their latest updates. And so, this web site was born.

I hope it gets used frequently so we can all benefit from it together. I look forward to hearing your thoughts.

Let me know what you think!

I don't know what one thing you're referring to, but it's a core principle of HN to try to avoid repetition, and especially the repetition+indignation combo, which is the commonest and most tedious thing on the internet.
