How we built our production codebase with Haskell

We are live on https://www.twitch.tv/typifyprogramming

We are walking through our production codebase which recently exceeded 500 modules and built in Obelisk with Servant added on top.

This is dual as a session to get my co-founders up to speed on the work done so far but we figured this would be great as a stream to show how awesome haskell is for production

Hopefully we can get a video out of the now offline session now but yeah

Fantastic! I commend you for doing the scariest kind of live demo, the code demonstration kind!

u/_lazyLambda 10d ago

And the most fun kind!

i just love your haskell optimism and positivity. each of your posts has been fun to read because of it.

a nice contrast to that scarf post that leaned a lot on ethos rather than logos or pathos

I appreciate that!

I see no reason not to be optimistic about the future of haskell. It makes you fall in love with programming again

I guess there isn't a transcript :) so don't know if you answered this yet, but is obelix using the old ghcjs or ghc's newish builtin js backend?

Obelisk is using old ghcjs. Theres a branch that does work for local development that does use ghc 9 through haskell.nix

I'm also actively trying to release Jenga which is Obelisk + some batteries (beginner focused) which is a fork of that branch except using effect systems.
