This is an example, written in javascript (node.js), of a RES service with collections and resource references to books, which can be created, edited and deleted.
- It exposes a collection,
library.books, containing book model references. - It exposes book models,
library.book.<BOOK_ID>, of each book. - It allows setting the books' title and author property through the
setmethod. - It allows creating new books that are added to the collection with the
newmethod. - It allows deleting existing books from the collection with the
deletemethod. - It verifies that a title and author is always set.
- It resets the collection and models on server restart.
- Have NATS Server and Resgate running
- Have node.js installed
