How To Angularfire2 Remove() By Some Key Value

I am trying to delete comments of a particular thread orderby some key(sid) value. eComments 0b4080bb4e686f003aaa340f8ed2e2a6 cid: '0b4080bb4e686f003aaa340f8ed2e2a6' comment

Solution 1:

This is one way:

const commentList = this.af.database.list('/eComments', {
      preserveSnapshot: true,
      query: {
        orderByChild: 'sid',
        equalTo: sid
      }
    });
commentList.subscribe(snapshots=>{
    snapshots.forEach(snapshot => {
      snapshot.ref.remove();
    });
})

I am not an AngularFire2 expert, so there might be easier/more idiomatic ways.
