Re: [elm-discuss] can't understand compiler error

In Elm you don't have statements, only expressions and the if model.flag == True then expression was not completed. It needs the else branch You cannot update the model in the view, only in update. On Wed, Feb 22, 2017 at 8:08 PM, Anurup Mitra wrote: > Hello! > >

What does Json.Decode.decodeValue returns? Can you share some code? On Fri, Feb 17, 2017 at 7:09 PM, Rex van der Spuy wrote: > Yes - how would I get the Err result? > > -- > You received this message because you are subscribed to the Google Groups > "Elm Discuss"

Re: [elm-discuss] I wish ELM could just be used in the browser

Elm was designed to help with reliability and maintainability of large scale apps. If it is a toy app or if reliability and maintainability are not important enough, other technologies are more appropriate. It depends on what you want to optimize on. If however reliability and maintainability

[elm-discuss] Using Elm on the server (full stack Elm webapps )

Hello community, I thought that using elm on the backend would be hard but it turns out that it is easy. I took the websockets example and turned it into a stand alone webapp. https://github.com/pdamoc/elm-sapling The approach that I used is to describe an API between the client and the server.

You need the --assume_function_wrapper flag. Also, if you have more troubles you could also drop the compilation level to SIMPLE. The difference should be no larger than few kb in gzipped form. It is worth mentioning that at such small sizes, even the unminified output gzips to very tiny sizes.
