Can not be used in the client part

[picca]

Hello

while working on an API, I end up with this error

/home/experiences/instrumentation/picca/autoprocess-exe/src/Web.hs:95:32: error:
    • No instance for (Servant.API.ContentTypes.MimeUnrender
                         HTML (Text.Blaze.Internal.MarkupM ()))
        arising from a use of ‘client’
    • In the expression: client myApi
      In a pattern binding: postJobSpecSub :<|> homepage = client myApi
   |
95 | postJobSpecSub :<|> homepage = client myApi
   |                                ^^^^^^^^^^^^

--  While building custom Setup.hs for package autoprocessing-0.1.0.0 using:
      /home/experiences/instrumentation/picca/.stack/setup-exe-cache/x86_64-linux/Cabal-simple_mPHDZzAJ_2.0.1.0_ghc-8.2.2 --builddir=.stack-work/dist/x86_64-linux/Cabal-2.0.1.0 build lib:autoprocessing exe:autoprocessing-exe --ghc-options " -ddump-hi -ddump-to-file"
    Process exited with code: ExitFailure 1

So my question is what is the proper way to use the client part in an API

Cheers

There aren’t MimeUnrender instances. blaze-markup (and lucid) are ”write-only” libraries, they don’t contain HTML parsers. There are HTML libraries though, but I don’t know if anyone made Servant bindings for them

I just need the write-only part in my server part with blaze. But I need also to create a client part for the other entry points. So in mycase h1 :<|> h2 = client myAPI is it possible to avoid the h2 and use only a subset of myAPI

[phadej]

type RestApi = ...
type HtmlApi = ...

type Api = RestApi :<|> HtmlApi

h1 = client restApi

[picca]

h1 = client restApi

did you mean ? h1 = client RestAPI

[phadej]

restApi = Proxy :: Proxy RestApi

[picca]

restApi = Proxy :: Proxy RestApi

thanks a lot, I will test this tomorrow :)

can't MimeUnrender return a ByteString in this case? Or is it required to be bijectional to MimeRender? The class itself doesn't have this constraint it seems https://hackage.haskell.org/package/servant-0.18.2/docs/Servant-API.html#t:MimeUnrender
