Need help with getting data from publishComposite

Hi all,

I am trying to get article specific data from multiple collections. I found publish composite makes it easy to get that data easily. I have tried it with blaze works fine with it, and now I am trying to get it working with react. I am facing problem while using it with react. I got my main data in json article field and now not getting how to get other data related to that. Here is my code as follows:

    return {
      articles: Articles.find().fetch(),
      author: Meteor.users.findOne(this.authorId)
    return (
          return <ShortArticle key={article._id} article={article} author={} />

Any suggestion or help is welcome.
