feat(query): in and array-contains-any operators

[Harrison Lo]

What is the feature?

Firebase team just introduced in and array-contains-any 2 days ago!

Do you have thoughts/examples on how the feature would be used (i.e. API)?

Thanks for posting, this is already supported since queries are passed directly though!

You would do it like so within a component (if you are using react-redux-firebase's hooks):

function SomeComponent() {
  useFirestoreConnect([
    {
      collection: 'projects',
      where: ['shared-with', 'array-contains', '123abc']
    }
  ])

  // Get projects from redux state
  const projects = useSelector(state => state.firestore.ordered.projects)
  // ... rest of component
}

If not using hooks you would do the following:

firebaseInstance.setListeners([
    {
      collection: 'projects',
      where: ['shared-with', 'array-contains', '123abc']
    }
  ])

Same thing with the in operator. To be sure, I tested within the complete example project, but reach out if things aren't working as expected.
