Prisma

Will server-side subscriptions also be implemented for files? They currently dont seem to be triggered.

<@U5HPPM67J> hey :wave: what's your use case for this?

Hey. My goal is to generate preview images of uploaded files and show them in the UI before the file is attached to a document.

nilan unfortunately not, I need to support PDFs, so a single file upload might result in previews of multiple pages

Gotcha. You can have another type that's one-to-one connected to the `File` type, let's call it `Document`

<@U0RQY0KK5> I should probably add a new type, something like "DocumentFile", and subscribe to that. I would not want to trigger this if my application would for example support uploading avatars or something like that in the future

then whenever a document is created, you have a server-side subscription for that

yes, right. I think I was just keen to use "File", because that's how I call these things in my domain model

I have Documents which have one or more Files :slightly_smiling_face:

but still: it would be nice if you guys would add documentation about subscriptions not working for files

lost some time there because it was the first subscription that I tried and I was confused when it didnt work

thanks that's a great suggestion! Will add this right away

did you encounter other limitations that confused you?

not really, I followed discussions in the GraphQL community around file uploads, so I already kinda expected that they would be handled outside of GraphQL proper

but I guess to newcomers this could be stated more explicitly

unrelated question: do you plan to support custom mutations via functions too?

e.g. if I would like to implement a subset of my application using event sourcing, it would be nice to delegate these mutations to a separate backend, which would in turn send mutations back to graphcool

not sure how well this would work in the real world, but it's something that crossed my mind

yes, that's a major part of our road map :slightly_smiling_face: you can track progress here: <https://github.com/graphcool/feature-requests/issues/40>
