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.

Building problems for using `Asterius` to compile Haskell to Webassembly.
I've encountered a building problem when using asterius to compile a multi-packages cabal project, the detail could be found here, any suggestions?

Options for a frontend of demo for a toy app
ghcjs is the way to go for you, and soon it might be asterius. i do not know how hard it is to set ghcjs up without a framework. but frameworks like obelisk (based on reflex-dom), shpadoinkle, and miso automate that for. i personally like obelisk for its functional reactive programming but it can get awkward and get in your way. so if gui programming is just a means to the end of this one small application and you are not really interested in it nor functional reactive programming, shpadoinkle or miso might suit you better. miso implements the elm architecture (also "TEA", "functional model view controller") and shpadoinkle implements something directly equivalent to the elm architecture. but shpadoinkle achieves more composable widgets by minimalizing the elm architecture. so i recommend shpadoinkle for its better concept although miso is more mature.

hint: Runtime Haskell interpreter
Also, hint uses unsafeCoerce, and thus implicitly relies on an assumption about how values are represented at runtime. Namely, if a program P is interpreting an expression E of type A, hint assumes that the value of type A produced by the ghc interpreter has the same representation as the values of type A which are manipulated by program P. This is not guaranteed to be the case, since P has been compiled by the compiler portion of ghc while E has been evaluated by the interpreter portion of ghc. This means the ghc devs had to carefully craft their compiler and interpreters to match. When targetting the browser, a Haskell-to-js or Haskell-to-wasm compiler such as Asterius modifies ghc's code-generator so it produces js or wasm code. You would thus also need to tweak the interpreter so that it produces js or wasm values which match what the modified code-generator outputs. Or you could restrict yourself to the hint's less expressive eval :: String -> String API.

M1Pro Woes
We found a post where someone had a similar issue (here), but the fix in that issue doesn't help: using `ar` from `binutils` causes link errors like this instead:
-
Pandoc in the browser w/ lua (possible contract gig?)
https://github.com/tweag/asterius/issues/851 (asterius has a demo, but no source, and I -assume no lua filter support)

It seems like every top tier team I work in insists on Yarn over NPM, almost unanimously it seems like all of these killer devs know Yarn is the industry standard on serious projects. Why do all documentation across the web default to npm installation instructions and assume you're using npm?
All modern ones support Haskell: https://github.com/tweag/asterius

Is GHCJS stuck on GHC 8.6.5?
Another option is Asterius. I'm not familiar with the current state, and it's not had active development for about 3 months now, either, so it may be in the same boat? But I think the big disadvantage of Asterius is that there's just a lot less usage, and therefore a lot less testing with the whole Haskell ecosystem, versus GHCJS which has been a fixture for a while and where loads of people have thought about compatibility for years.

WebAssembly Studio
I've played around with Haskell via the Asteruis project : https://github.com/tweag/asterius
Also emscripten of course, for C/C++.

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.
