Proposal: unwrapCollection and unwrapDocument operators

[davideast]

Easier access to a document’s ID

Getting the id mapped to a single document has also long been a pain point, so we thinking of introducing a new operator to simplify this process:

Collection

// using the new docs property in issue #1819 
const items$ = af.collection(‘items’).docs
  .pipe(
     unwrapCollection({ id: ‘key’  })
  )
  .subscribe(items => {
    const first = docs[0];
    console.log(first.key); // they id is mapped to each object!
  });

Document

// using the .doc property in issue #1819 
const items$ = af.collection(‘items/1’).doc
  .pipe(
     unwrapDoc({ id: ‘key’  })
  )
  .subscribe(item => {
    console.log(item.key);
  });

Leave a comment letting us know what you think.
