GraphqlApolloUploadClientParams

apollo-client v2 + rails (graphql-ruby) to upload files in mutation.

// if upload a file like this
this.props
  .mutate({
    variables: {
      file: uploadingFileObject
    }
  })
  .then();

# then the server receives params like this
# params[:operations] => json containing query and variables
# params[:map] => json containing uploaded file mapping data
# params["0"..] => number string key containing the actual file object ActionDispatch::Http::UploadedFile

class GraphqlController < ApplicationController

  def execute
    # this gem will try to convert the params to useful variables, query, operation_name
    converted_params = GraphqlApolloUploadClientParams.convert(params)
    variables = converted_params.variables
    query = converted_params.query
    operation_name = converted_params.operation_name
