tagless-final VS FS2

https://github.com/devinsideyou/tagless-final Full disclosure: it's mine. Note: there are 2 projects in this directory and so `todo` is the one you want.

Recently, CE3 has had similar issues reported across multiple repositories, almost an epidemic of reports!

Thanks for the explanation!

So it's pull based and not push based like most other streams lib.

Does maybe someone know how this compares to FS2 or Iteratees than? (Both are also pull based streaming solutions).

Looks quite similar to me. Is the Scala FS2 lib maybe even a clones of the Haskell solution? Or are they different in important aspects?

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

On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.

fs2 for streaming.

As of very recently, we're using ScalablyTyped in our fs2-io cross build for node. https://github.com/typelevel/fs2/pull/2453

In that case, it's best to keep different streaming libraries separate, in their own little "worlds". fs2 + cats has Queues for this purpose https://fs2.io/#/concurrency-primitives. Future has the Promise abstraction.

ScalaZ was changed to cats-effect. For streaming, look at fs2. Cats-effect 3 cleans up a lot of the library, but as with any code it can be clean or messy depending on the dev

Watch the talk "Streams - Your New Favorite Primitive" by Ryan Peters (aka sloshy) and then looking into the docs of fs2. - This one to learn one of the most used / useful libraries of the typelevel ecosystem to process data.
