Google-cloud-java: FireStore Realtime functionality

[Klabauterman]

I would like to know if there is FireStore realtime functionality like in the android SDK is planned. The old firebase admin SDK had it.

Thanks in advance.

Firestore is not realtime database. You can still use realtime database and firestore.

But the Firestore client-SDKs for web, android and ios support data listeners: https://firebase.google.com/docs/firestore/query-data/listen

We will confirm with the Firestore product team. Taking this until I find the right contact.

This is on the roadmap for the rest of the Server SDKs. It's already available in Node. Stay tuned!

Cool, thanks 👍

Hey guys, probably not the best place to ask, but I am also trying to implement listen in a Java Project. I am trying to set this up with REST API. Does anyone knows a valid object for it?

I just tried:

{
 "addTarget": {
  "targetId": "alovelace",
  "once": false,
  "documents": {
   "documents": [
    "room"
   ]
  },
  "query": {
   "structuredQuery": {
    "from": [
     {
      "collectionId": "room"
     }
    ]
   }
  }
 }
}

Whenever I try, always get:

{
 "0": {
  "error": {
   "code": 400,
   "message": "Invalid value (Object), ",
   "status": "INVALID_ARGUMENT",
   "details": [
    {
     "@type": "type.googleapis.com/google.rpc.BadRequest",
     "fieldViolations": [
      {
       "description": "Invalid value (Object), "
      }
     ]
    }
   ]
  }
 }
}

Please take a look at the Node API and turn on logging to see a dump of the request trace:

Firestore.setLogFunction(console.log)

That might help you.

The documentation still not yet updated. https://firebase.google.com/docs/firestore/query-data/listen
Have anyone tried how to implement this?
