// 1. Use publish composite
See examples: https://github.com/englue/meteor-publish-composite

// 2. Write a publish function that returns an array of cursors
Meteor.publish('books', () => {
  const bookCursor = Books.find();
  const authorIds = Books.map((book) => book['authorId']);

  const authorCursor = Authors.find({_id: {$in: authorIds}});
