postgraphile-derived-upload-field

Thanks to https://github.com/graphile-contrib/postgraphile-plugin-upload-field for the amazing plugin and @benjie at https://www.graphile.org/ for all the support!!

This plugin is a modification of the upload field plugin in that this creates a derived field, which allows you to either upload or patch the original type.

Postgres

This plugin requires some modifications to your schema. You can author your schemas with custom domains like image, attachment, or upload, or even just add @upload into your comments to create upload fields:

create table public.post (
  id serial primary key,
  header text,
  body text,
  icon text,
  image image,
  attachment attachment,
  upload upload
);

comment on column public.post.icon is E'@upload';

If you want to see the types, checkout https://github.com/pyramation/pg-utils/blob/master/packages/types/sql/types--0.0.1.sql

Graphile Settings

Register your types, tags, and your resolve function for uploading files:

    graphileBuildOptions: {
      uploadFieldDefinitions: [
        {
          name: 'upload',
          namespaceName: 'public',
          type: 'String',
          resolve: resolveUpload
        },
        {
          name: 'attachment',
          namespaceName: 'public',
          type: 'JSON',
          resolve: resolveUpload
        },
        {
          name: 'image',
          namespaceName: 'public',
          type: 'JSON',
          resolve: resolveUpload
        },
        {
          tag: 'upload',
          resolve: resolveUpload
        }
      ],
