Haste is a GHC-based compiler that translates Haskell programs into JavaScript, supporting most GHC extensions and standard Haskell libraries. It provides type-safe client-server communication, JavaScript interoperability, and Cabal integration for building web applications in Haskell.

Use cases

compile haskell to javascript
build web apps in haskell
run haskell code in the browser
type-safe client-server communication in haskell
interoperate haskell with javascript dom apis

When to choose

you want to write browser applications in Haskell with GHC extensions
you need a single-program framework for Haskell client-server web apps
you want simple JavaScript FFI from Haskell

When to avoid

you need an actively maintained compiler - the last release was 2019
you need Template Haskell support
you prefer modern alternatives like GHCJS or GHC's JavaScript backend
