Hey folks, I’ve got a nexus question (since I’ve finally been convinced that code-first makes sense for large projects). With

nexus

, where should I put business logic that I want to run when fetching/saving types? i.e. not just field resolvers, but whole types

e.g. when saving a Tag, I want it to check user auth, not just in my

updateTag

mutation, but in any mutation where Tags might be saved (e.g. through nested/related updates:

updateArticle

with

{ tags: { create: { some tag data }}

)

right now (with apollo-server 2 and SDL type defs) I’ve got each of my resolvers/<type>.js exporting

get

and

patch

functions, which are called in mutations, queries, and other types’

get

and

patch

functions

e.g.

updateArticle

calls

Article.patch()

which calls

Tag.patch()

(checking user auth for tags) and then the returned Article object is sent to

photon.articles.update()

I know this isn’t an unheard of pattern, but what would be the

nexus

-y way to do similar stuff? middleware? stuff in the

definition()

method?

can I do this?

Copy code

const MyNode = objectType({
  definition(t) {
    t.string('foo', () => 'result')
  },
  resolve(o) {
    // business logic
    return photon.mynodes.findOne(o.id)
  }
}

I see that

t.field()

accepts an

authorize

property, but that would mean I’d have to do all auth and full type resolvers at the edges

which is doable but feels real gross, since Tag is what cares about auth/resolving, not Article.tags (and Image.tags, and any other edge to tags that I don’t want to accidentally forget to protect and thus expose a glaring security hole in my api)
