Handling file uploads?

[isocra]

Hi,

I know this isn't really an issue with your excellent packages, but I'm stuck. I have an app used by engineers to take photos of a work site. They're often offline. I used to use the AWS AppSync SDK which had a feature that would transparently upload photos to S3. Unfortunately they're not maintaining it now and it doesn't work with the latest React Native, Apollo or Expo, so hunting around I found these packages which work really well.

Unfortunately I can't find a way to handle images though. I tried turning the image into Base64 and then setting a property. This works OK as long as the image isn't very big. But I soon got errors from our AppSync server with medium-sized photos. I also got problems on the device saying the data was too large for the cache.

I've just been looking at Expo SDK38's new FileSystem.uploadAsync. This looks very neat because it works in the background, but I can't make it work with Android, only iOS so far and I'm not sure how to integrate it with GraphQL.

Any ideas anyone?
Thanks

Hi @isocra,
in AWS AppSync this is solved by creating a specific Apollo link:
https://github.com/awslabs/aws-mobile-appsync-sdk-js/blob/master/packages/aws-appsync/src/link/complex-object-link.ts

You could open a ticket and request that this link be distributed as an independent library, as they did for it here (https://github.com/awslabs/aws-mobile-appsync-sdk-js/tree/master/packages/aws -appsync-auth-link)

For Relay I did the same:
