http4s: pure, typeful, functional HTTP in Scala - Ross Baker

http4s embraces cats.data.Kleisli for service definitions and fs2.Stream for payload processing. With its foundation on these simple types, we’ll take a whirlwind tour of how http4s can:
plug into your functional business logic
snap together with other functional libraries
relate servers to clients
test with a simple function call
run on multiple backends
support multiple higher level DSLs
This talk will not make you an expert in http4s, but show that it’s a relatively short path to become one.

At 14:00, you may have a slight error in your ending punctuation. I did really get a lot out of the presentation. I had to squint a lot though to read through the blue Listerine screens. Slides are total quality. Did I say this was a good presentation? I meant GREAT!

[@rossbaker9079]

Thanks! Do you mean the `})}}` on the last line? All the code in the slides is compiled, thanks to sbt-tut. There's unfortunately a horizontal scrollbar on that slide.

[@gmicolor5663]

Awesome!

The channel called 'Coding Tech' uploaded exactly the same video as this one about three months ago. Did Typelevel allow it? Here is the link to the video. kzbin.info/www/bejne/nqGufHeNiceXhrM I know the licence of this video is "Creative Commons Attribution licence (reuse allowed)" but I'm not sure if uploading the same entire video to their own channel is allowed.

Thanks for the hint. The license allows it and they put the proper attribution in, so there's no action required from our side.
