Is there a reason why you first declare importableResources and then change the values? The way it was before I felt it was easier to grasp.

Otherwise it's looking great!

I liked the way it was done too, but I struggled to find a good way to conditionally insert the values while also keeping importableResources in the correct scope. I'm sure there's a better way to do it (there always is), but I think this way is good enough for now at least to fix the issue with not being able to fetch users. Doing it this way at least I know it's going to work every time.

If I get time in the next few weeks I'd like to revisit it to find those better ways, and also create some unit tests since there aren't any yet.

let posts = {} // because `posts` needs to be in a scope accessible by `links` below

const users = Object.keys(json.payload.references.User)
.map(key => json.payload.references.User[key])
importableResources = importableResources.concat(users)

if (json.payload.posts) {
posts = json.payload.posts
importableResources = importableResources.concat(posts)
}

if (json.payload.references.Post) {
posts = Object.keys(json.payload.references.Post)
.map(key => json.payload.references.Post[key])
