Fable: Compile FSharp.Data.GraphQL Client got some strange errors

[zaaack]

I'm trying using FSharp.Data.GraphQL(nuget version) in safe-stack, the ionide editor worked with graphql type provider, but when I build with webpack, at first it throws 1 error, then GraphQLTypeProvider cannot find, then there are no build errors, no console errors, but the async query code just not working.

Then I tried to debug with fable-spliter, but got this error:

Hehe, I've nightmares with GraphQL :wink: I wrote the Fable part for the GraphQL provider (defined within #if FABLE_COMPILER directives) but I did it with a previous version of Fable and haven't tried with the latest one. Unfortunately I'm not able to maintain the provider any more (I also don't think that GraphQL is a good fit for F#, but this is a personal opinion). I don't know what's the cause of the problem but looking at the error maybe it's just a spelling issue? Maybe related to this line?

BTW, in any case it seems Type Providers are working with Fable, this is good news.

[zaaack]

@alfonsogarciacaro Thanks! I can't believe I didn't notice the message , I'll try it today. Actually I notice your great work in FSharp.Data.GraphQL, the main reason I choose.

BTW, I think GraphQL might not be needed in safe-stack, but at least it's the most popular cross-language server-client protocol with good tooling, the best choice to communicate with clients write in different language, in my case, is android(java) for now.

[zaaack]

@alfonsogarciacaro I tried, looks like this isn't a typo. Still don't know what's the reason, and the build error are not show every time. The query async method can execute util before the query, but no request.

[zaaack]

The FSharp.Data.GraphQL.Client project requires net45, and used some API that does not exist in dotnet core 2.0. Would this be the problem?

[alfonsogarciacaro]

Could be, a workaround seems to be needed to run TPs on netcore but I don't know the details :/

[zaaack]

Actually I did this trick already...

[zaaack]

Still no luck, can fable build using mono? Or the best way to do is not using Type Provider for know, which might not be a big deal, and waiting for type provider support dotnet core.

[alfonsogarciacaro]

Yes, you should be able to compile Fable for .NET Framework, you only need to change the target framework of the project files and define the NETFX directive. Unfortunately, I cannot maintain another target with different build process, publishing, distribution, documentation, maintenance, etc. so if you need it you'll have to create a custom build.

I was indeed thinking to wait until Type Providers are better supported in NETCore, I know they are very cool and it'd be great if you or someone in the community could check how to make them work with Fable, but at the moment there are other things in the roadmap that I need to focus on :/

[zaaack]

I tried again, it seems it doesn't generate any type in fable, but also doesn't produce any other error..I'll keep watching, hoping it won't take too long for dotnet core to support type provider..

[zaaack]

According to dsyme, currently FCS doesn't support TP when targeting netcoreapp 2.0, but it's already been fixed in Microsoft/visualfsharp(without much test), and still need some time to merge into FCS, but I also notice Fable is using a fork of FCS (Fable.FCS), so this also need to update from upstream before we could test TP in Fable..

Just for reminding me or someone else don't forget to check it out after all is done ;) .
