Elm at Scale: More Surprises, More Pain Points

[@samuelvishesh]

Are you guys still using Elm?

[@KevinNYank]

Not for anything new, but we still have a couple of active Elm codebases. See my blog post: kevinyank.com/posts/on-endings-why-how-we-retired-elm-at-culture-amp/

@@KevinNYank for what reasons did you stop using Elm in new projects? Are you able to sum it up overall from the perspective of so many years? I'm starting to learn Elm and I'm a bit worried about whether it's a COBOL-style learning venture

[@KevinNYank]

@@coder_one I certainly can! kevinyank.com/posts/on-endings-why-how-we-retired-elm-at-culture-amp/

It's been over a year and I'm really curious how it's been going with ELM. Did you find any pain points besides the "DOM is off-limits" you couldn't solve?

[@Joy-om2iu]

Pricey as a gem! This is a MUST watch! Thank you for sharing your experience.

[@ericka.montanez6821]

This is gold.

[@StephenTurley]

I'm really looking forward to your 0.19 Suprises and Pain Points. I think this is a great format.

[@MBJ2323]

Thanks for both videos, it's always good to have reliable reviews from people using it in production!

[@solvm1652]

I love this series! How about elixir as well? What has that revealed?

[@ramstein74]

Great video and explanation. This is better than going to the oficial website.

[@BerenddeBoer]

It's odd to see Elm is like X, when in reality Elm was the inspiration for X.

[@joaopereira1219]

Awesome videos, looking forward for a follow up that takes the 0.19 version into account

[@danzmachinz2269]

More on webcomponents and jwts please. Thanks

[@simonkraus7533]

Dont you know how many items there are that you want to show and can't you just calculate 16*px_per_item to get the pixel value?

[@andynicholson7944]

Great presentation, thanks Kevin! PS. What mic do you use to record?

[@morthim]

i am impressed

[@LourensRolograaf]

Did you change over all lecacy to .19 and if so, how does the compiler perform now? And is your compiled JS seriously smaller?

[@LourensRolograaf]

@@KevinNYank it must be really great not to have to go through upgrading a large codebase very frequently, and if your worst pain points are being tackled in the upgrade, instead of the common featuritis with only unwanted bulk of new options?

[@YakovL]

@@KevinNYank cool! Looking forward to hearing how it goes for you. You also mentioned that 0.19 was planned to have those code splitting, tree shaking and other stuff implemented. Looks (elm-lang.org/blog/small-assets-without-the-headache) like you're right about only dead code elimination/tree shaking actually got implemented, which is still quite an improvement.

[@smackmybiatch]

@@KevinNYank how about now?

[@guidyouguy7306]

Very nice

[@dmitryplatonov]

Did you ever thought about switching to Purescript?

[@dmitryplatonov]

@@KevinNYank I had hello world example working in 30 min (opposed to 5 min in Elm), that is using Hedwig, which is very similar to Elm architecture. After my initial excitement over Elm, I found two major problems with Elm: 1) single person controls language and libraries 2) type system is limiting. You probably you felt (1) with 0.19, which killed custom operators and native modules. (2), among others, leads to non-existence of typeclasses, and because of that user-defined types cannot be used as keys in dicts. Lack of typeclasses leads to problems with code reuse and boilerplate. As for initial setup - it is done once in a project, so it's not a concern for longer projects. As general framework (not webapp-specific) it can be adopted to server-side rendering, and also some code sharing is possible between front and back. Elm is wonderfull tech, and easy to get into, but in some ways limiting - which would not be a problem if creator would not enforce his vision on all users.
