This article describes the procedure for preparing Apollo Server for file upload. There are instructions for 2 and 3.

Some notes:

• I've moved us to ApolloServer V3. This means we must integrate graphql-upload manually as described in the above link.
• graphql-upload requires node ^14.17.0 || ^16.0.0 || >= 18.0.0
• graphql-upload uses what the author calls optimal JavaScript module design. Functionally for us, what this means is that we can't do:

  import { GraphQLUpload  } from 'graphql-upload'

  But must instead do:

  import  GraphQLUpload  from 'graphql-upload/GraphQLUpload.mjs'

  Potato/Potahto, I guess.

This is complete with the implementation of the Images feature (b98a2c222790f33352cdf4911fdede1b9c7c2100 through c0fb06a113efa92280da55f43080a9284831f51c)
