Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
We haven't tracked posts mentioning webapp yet.
Tracking mentions began in Dec 2020.
An alternative front end for Haskell?

> do you really have to understand language extensions?
You do when your code doesn't compile and you're trying to figure out what the error message means, or when the library you want to use makes heavy use of it for even basic functionality.
> These days one just enables GHC2021
My experience was pre-GHC2021. I basically had to enable at a minimum 5-6 language extensions in every single file.
> Mostly they're just about removing unnecessary restrictions from the older standard.
Yeah, those ones are usually fine. I have zero objection to things like FlexibleInstances or DeriveFoldable.

I believe I was trying to implement Central Authentication Service using Servant. However, that required returning a custom HTTP status code. There has been an open Github issue for this since 2017, but it seems to require basically rewriting the entire framework: https://github.com/haskell-servant/servant/issues/732
Looking back at it now Servant does have "ServerError", but that basically requires giving up all the advantages Servant claims to have and I believe it was not a viable option at the time. Looking at the timeline I was probably also on Servant 0.15, and there seems to have been a rewrite since then.
I vaguely recall running into a similar issue trying to interact with a database, but I can't remember the details of that.
Monthly Hask Anything (November 2022)
3 projects | /r/haskell | 1 Nov 2022
If you don't like this style, the usual alternative is to change mkDualAuthHandler to take two additional arguments, Proxy tag0 and Proxy tag1 (as e.g. lots of Servant functions do, for historical reasons).
How introduce `ResourceT` into my stack

Dunno if this is helpful, but I found this github issue about ResourceT and servant https://github.com/haskell-servant/servant/issues/1345
Introduction to Doctests in Haskell
6 projects | /r/haskell | 19 Apr 2022
And what about the cabal repl --with-compiler=doctest, which was added recently, in doctest v0.20? I recently submitted a PR for Servant to use this in place of GHC environment files, because it seems less finicky to me. Was this a bad idea?
Generate Typescript from Servant API
5 projects | /r/haskell | 15 Mar 2022
I asked a somewhat relevant question recently. Maybe you'll find this discussion somewhat helpful: https://github.com/haskell-servant/servant/issues/1547; two packages were talked about. One of the folks from Well Typed replied, and said they tried it recently (and worked fine).
Named Routes in Servant
Hey, is it possible this could solve the quadratic compile times issue for Servant routes? I was under the impression the slowdown was related to GHC being slow processing giant types, so maybe breaking the API down into records is just the thing...
You'll actually have to use the unreleased servant-auth-server from master (see here for details). I need to push a release :-)
6 projects | dev.to | 5 Apr 2021
We use servant library that allows us to describe API at the type level and check during the compilation whether both the server handlers and the client functions use correct parameters of the required types and correspond to the current API version (if you forgot to change the client function at the frontend, it just won’t be built).
Saw a Tweet about Haskell+Servant being replaced with NodeJS in a project due to compile times - will compile times ever get better?
2 projects | /r/haskell | 23 Feb 2021
Since nobody has mentioned it yet, there is an outstanding issue about quadratic compile times in Servant.
