9 mins readPython Production Architecture: Cabal & Stack
In Plain English
Learn how production Haskell applications are organized, configured, and built using Cabal packages, Stack reproducible resolvers (LTS Haskell), and clean directory structures (src/, app/, test/).
Deep Dive: How It Works
Package Tools: Cabal (the core build system) and Stack (curated LTS snapshot package manager).
Directory Layout: src/ for core library modules, app/ for Main executable, test/ for test suites.
GHC Flags: -Wall (enable all warnings), -O2 (maximum optimization), -threaded (multi-threaded runtime).
Core Rules to Remember
Cabal & Stack Ecosystem: Standard tools for package management and reproducible compilation.
GHC Optimization Flags: Use -O2 -threaded -rtsopts for maximum production performance.
