The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Secretly introduced rust in my company, now they love it!
There is a fork that compiles to js https://github.com/ghcjs/ghcjs compiler, and I believe the official glasgow compiler is working towards also supporting js/wasm (although I don't think they are supported as of yet).

Resurrection/modernization of an old Haskell+Haste project (boardgame Yinsh)
I don't know anything about Haste, but you can get GHCJS 8.6 (or 8.10 with a bloated executable) via nix fairly easily or alternatively wait until the JS target recently merged into mainline ghc gets production ready: https://engineering.iog.io/2023-01-26-ghc-update.

How does GHC built from source set header search path?
Ah GHCJS does have this header: https://github.com/ghcjs/ghcjs/blob/ghc-8.10/lib/boot/data/include/stg/DLL.h
- Haskell, JS, and WebDev?
-
Status of GHCJS for larger projects
It seems like https://github.com/ghcjs/ghcjs/issues/821 is a rigid dealbreaker for any sizable project.
-
GHCJS or Asterius
About the FFI: GHCJS extended the FFI to support inlined JS, named arguments, etc. See https://github.com/ghcjs/ghcjs/blob/master/doc/foreign-function-interface.md For now the JS backend only implements FFI calls similarly to native FFI. The rest will be open to discussion later (e.g. in a ghc-proposal) and should take into account the Wasm backend so that the same user code compiles with both backends as much as possible.
- Just few questions on Miso and GHCjs
-
Memory from finished thread is not getting reclaimed
Other than that, I ran into a GHCJS and Miso bug, but they weren't too hard to solve.
-
GHC Pluggable Backend?
There are a bunch of open branches. And yes, there is ghcjs support in haskell.nix, see this comment.
-
Is GHCJS stuck on GHC 8.6.5?
When I compile the ghc-8.8 branch locally, I get a number of test failures from the test suite. I'm not sure exactly how to fix them and they aren't currently my highest hobby priority.

[ANN] Fourmolu 0.12 + new website released!
Great work! If I'm not mistaken, it looks like the web app is built using the new WASM backend for GHC which is a pretty nice example of a real-world application :)
