Firestore: how to perform a query with inequality / not equals

Question

I want select from Firestore collection just articles written NOT by me.
Is it really so hard?

Every article has field "owner_uid".

Answer 1

This is an example of how I solved the problem in JavaScript:

let articlesToDisplay = await db
  .collection('articles')
  .get()
  .then((snapshot) => {
    let notMyArticles = snapshot.docs.filter( (article) => 
      article.data().owner_uid !== request.auth.uid
    )
    return notMyArticles
  })

It fetches all documents and uses Array.prototype.filter() to filter out the ones you don't want. This can be run server-side or client-side.
