bontaq / user-example

A larger example using Purview and effects to create, and view, some users

User Example

Setup

1. Install ghcup, a command line tool to manage haskell
2. run ghcup tui
3. Install the tools to get it looking like this -- GHC 9.2.5, Cabal 3.6.2, HLS (haskell language server) 1.9.0, though realistically a more recent HLS and GHC should work (note the HLS powered though, definitely choose a GHC version with that).

VSCode

There is a plugin for Haskell, https://github.com/haskell/vscode-haskell, but you'll want ghcup installed first.

Running

1. cabal build
2. cabal exec user-example

File walkthrough

• Main contains the top level element and interpreter
• Server is the finer parts of handling web and websocket requests
• Router contains the route reducer, receiving an initial path then able to change it via events
• Pages contains the pages (just user creation and listing now)
• Services contains the user service

Automated formatted

Provided by https://hackage.haskell.org/package/fourmolu, configuration is in fourmolu.yaml

1. cabal install fourmolu (this will take awhile, it's a big boy)
2. fourmolu -i src to format all files
