admin can't create post, we validate if is admi by email.

localhost:3000/posts

{
   "title":"flux zone come back",
   "authorEmail":"alice@prisma.io"
}

Not Authorized

admin can approve/reject post

localhost:3000/posts/1/publish

{
   "userId":"1"
}

localhost:3000/posts/1/reject

{
   "userId":"1"
}

another endpoints :).

list all post of a user

localhost:3000/posts/2/author

{
    "userId":"2"
}

admin can list all posts.

localhost:3000/posts

{
    "userId":"1"
}

note

I'm not implementing session/cookies, it's just a simple example of Implementing State Machines (FMS) with roles assigned.

I am going to implement JWT for the next improvement
