Case Study — Using a JavaScript component inside a Haskell application | The Haskell Programming Language's blog
Mateusz Goślinowski January 08, 2025 [GHC] #javascript #case-study GHC since version 9.8 allows us to create callbacks from JS to Haskell code, which enables us to create full-fledged browser apps. This article shows how to use the JS backend with foreign component libraries. repository: https://github.com/Swordlash/halogen-blog ghc used: javascript-unknown-ghcjs-ghc-9.12.1 (ghcup) Preface Any use
JavaScript backend merged into GHC | IOG Engineering
A new JavaScript backend was merged into GHC on November 30th, 2022! This means that the next release of GHC will be able to emit code that runs in web browsers without requiring any extra tools, enabling Haskell for both front-end and back-end web applications. In this post, we, the GHC DevX team at IOG, describe the challenges we faced bringing GHCJS to GHC, how we overcame those challenges, and
Oleg's gists - Compiling Haskell to JavaScript, not in the way you'd expect
#Step 1: Template Haskell splices The [d| ... |] is a syntax of Template Haskell declaration quote. For example, [d| answer = 42 |] would produce a value of type Q Dec, which is an abstract syntax representation of it. Relatedly, the $(...) is splice syntax. As it appears on the top level, it splices declarations (of the type Q [Dec], or expressions of the type Q Exp depending on the context) into
js-good-parts
An AST for the "the good parts" of Javascript (as defined by Douglas Crockford) and a pretty printer for that AST. Designed to be the target of a code generator. Does not include a parser.

haste-compiler
This package provides a featureful compiler from Haskell to JavaScript based on GHC. It generates small, fast code, makes use of standard Haskell libraries, integrates with Cabal, supports most GHC extensions and works on Windows, Linux and OSX. Non-Linux users are strongly recommended to download pre-built binary packages from haste-lang.org instead of building from source.
Introduction to Fay - 純粋関数空間
Fay をいじってみたので、 せっかくだから記事を書いておこうと思います。 なお、Fayは新しい言語（というより、処理系と言った方が適切かな）ですので、 ここに書いてある情報は、来年か、あるいは半年後か、 それとももっとずっと早くに陳腐化する可能性がそれなりに低くないことを、 あらかじめお断りしておきます。 この記事執筆時に用いたFayのバージョンは、 fay-0.14.5.0 です。 デモ・前置き 特に何か作りたいものが有ったわけではなかったので、 今回作ってみたものは超どうでも良いツールです。 http://tanakh.jp/tools/sudden.html ＿人人人人人人＿ ＞ 突然の死 ＜ ￣Y^Y^Y^Y^Y￣ こういうテキストを生成するだけのツールです。 Fayのコード HTMLコード これらのコンパイルなどもhakyllでまとめて管理できるようにしました。 hakyllに
実装して理解する遅延評価の仕組み 〜 thunkを絵に描いて理解しよう・JavaScriptでHaskellを実装！？ - プログラムモグモグ
この記事では, Haskellに用いられる「遅延評価」の仕組みを, 図に描いて説明します. 更に, 遅延評価版のフィボナッチ数の無限列を, JavaScriptで実装します. 遅延評価とはどのように動くのか, 考えて行きましょう. HaskellのコードとJavaScriptのコードの比較 Haskellでの x = y y = 10 と, JavaScriptの var x = y; var y = 10; というコードを考えてください. Haskellのコードは, これだけでは何も起こりません. print xとすると, x = y = 10 となって 10 が表示されます. 一方, JavaScriptのコードは var x = y; を評価した瞬間, ｢ReferenceError: y is not defined｣というエラーが出ます. 更に, main = let x = 1

Breakout
Hi, welcome to the 5th article of this blog. I am very exited! In the last Post we wrote a Pong like ... well ... let's call it javascript application. In this post I have expanded it by the following properties: The game does not start until you hit enter. There are blocks that can be hit by the ball and disappear. There are even blocks with 2 lives (dark blue) that turn into normal blocks on the
