* Haskell to Web compilation survey
There are three haskell to web compilers in varying maturity levels.
- [[https://github.com/ghcjs/ghcjs][ghcjs]] the oldest haskell to web compiler that produces JavaScript.
- [[https://github.com/tweag/asterius][Asterius]] a haskell to webassembly compiler.
- [[https://github.com/WebGHC][WebGHC]] a webassembly code generator for ghc.
** Building
Please refer to the relevant notes regarding building of the
compilers.
| | Linux | macOS | Windows |
| ghcjs | Yes | Yes | |
| Asterius | Yes | No | |
| WebGHC | Yes | Yes | |
Notes: [[ghcjs-build-notes.org][ghcjs]] [[webghc-build-notes.org][WebGHC]]
** Features
** Compiling applications / libraries
*** ghcjs
**** building
#+BEGIN_SRC bash
cabal new-build --project-file=ghcjs.project --ghcjs exe:$app -fexamples --allow-newer
#+END_SRC
**** optimizing
One option is to pass ~-dedupe~, which should reduce the resulting
size. The other is to use googles closure compiler to optimize it.
It turns out that sometimes ~-dedupe~ will increase the size, but
make the result more favorable to the googles closure compiler.
#+BEGIN_SRC bash
ccjs all.js --compilation_level=ADVANCED_OPTIMIZATIONS --jscomp_off=checkVars --externs=node --externs=all.js.externs > all.adv.min.js
#+END_SRC
(see [[https://github.com/ghcjs/ghcjs/wiki/Deployment][ghcjs deployment wiki]])
*** Asterius
**** building
#+BEGIN_SRC bash
#+END_SRC
**** optimizing
*** WebGHC
**** building
#+BEGIN_SRC bash
wasm32-unknown-unknown-wasm-cabal new-build --project-file=webghc.project exe:$app -fjsaddle-wasm -fexamples --allow-newer
#+END_SRC
**** optimizing
The wasm files could be optimized with ~binaryen~'s ~wasm-opt -Os~.
Webpackifying the javascript support could result in dramatic
savings. (TODO)
