Example request GeoFirestoreQuery about geofirestore-js HOT 4 CLOSED

Hi @Morzilla, I implement geofirestore in my project as well and I believe I can help.

You already add/set users to firestore, here is the relevant part.

Here I showing markers in a map inside a circle representing a radius

 const collectionRef = this.affirestore.collection('publications').ref;
      const geofirestore = new GeoFirestore(collectionRef);

      const queryCriteria: QueryCriteria = {
        center: [this.circle.latitude, this.circle.longitude],
        radius: this.radius
      };

      this.geoQuery = geofirestore.query(queryCriteria);
      this.showPublicationsMarkers();
    ...
showPublicationsMarkers() {
...
    this.geoQuery.on('ready', () => {
      console.log('GeoFirestoreQuery has loaded and fired all other events for initial data');
    });

    const onKeyEnteredRegistration = this.geoQuery.on('key_entered', (key, location, distance) => {
      console.log('key_entered');
      console.log(key, location, distance);
      this.publications.push({ key: key, coords: { lat: location[0], lng: location[1] }, distance: distance });
    });

    const onKeyExitedRegistration = this.geoQuery.on('key_exited', (key, location, distance) => {
      console.log('key_exited');
      console.log(key, location, distance);
    });

    const onKeyMovedRegistration = this.geoQuery.on('key_moved', function (key, location, distance) {
      console.log('key_moved');
      console.log(key, location, distance);
    });

  }

On every callback you have access to

• document key
• geopoint
• distance

Sorry I am not at pc right now, so believe things like formatting might be wrong

@akaisuicchi , you pretty much got it on point.

@Morzilla You're the second person to bring up how it's difficult to follow without an example application. So I'm actually working on one for version 2.0.0. I will be closing this issue (because of the answer above, and this isn't really an issue, more of a question).

Considering it is just an implementation question I'm curious if anyone has thoughts as to wether a gitter or stack overflow tag would be appropriate for things like this moving forward?

@akaisuicchi Thank you, i did it with the "key_entered" event (I have the user's uid in the GeoFirestore reference document).
@MichaelSolati Maybe you could add just a couple of examples, like the one I asked, just to give a "starting point" for a new user like me, and yes, it could be the right way to use SO for questions/problems and GH for issues only...

Again, thanks both for your kindness!

@MichaelSolati a SO tag might be better but gitter could be too.

Questions and doubts for SO and real issues or improvements for GH is what other people/projects try to do.
