Creating or deleting multiple batches of entries in Firebase Realtime Database

Question

Creating or deleting multiple batches of entries in Firebase Realtime Database

I am currently utilizing Firebase real time database in the following way:

 createSoldLead(soldLead: SoldLeadModel): void {
    const soldLeadsReference = this.angularFireDatabase.list<SoldLeadModel>(
      `groups/${this.groupId}/soldLeads`
    );

    const leadsReference = this.angularFireDatabase
        .list<SoldLeadModel>(
      `groups/${this.groupId}/leads`
    );

    soldLeadsReference.set(soldLead.id.toString(),soldLead);

    leadsReference.remove(soldLead.id.toString());
  }

The current implementation is functioning correctly. However, I am interested in performing a batch create/remove operation. Is there a way to ensure that both operations succeed simultaneously?

I came across this blog post, but I am unsure how to apply it to my specific scenario. Can anyone provide guidance on how to implement this in my case?

By utilizing a single multi-path update, you have the ability to write to multiple nodes on various paths simultaneously.

You can achieve the equivalent of making two separate calls by implementing the following code:

let updates = {};
updates[`groups/${this.teamId}/completedTasks/${task.id}`] = task;
updates[`teams/${this.teamId}/tasks/${task.id}`] = null;

firebase.database().ref().update(updates);

If you set a node's value to null, it will effectively remove that particular node from the database.

Displayed below is the code snippet for creating a SOLD LEAD using AngularFire.

createSoldLead(soldLead: SoldLeadModel): void {
    const updates = {};

    updates[`groups/${this.groupId}/soldLeads/${soldLead.id.toString()}`] = {
      ...soldLead,
      createdBy: this.createdBy,
      createdDate: this.cre
    };

    updates[`groups/${this.groupId}/leads/${soldLead.id.toString()}`] = null;

    this.angularFireDatabase.object('/').updates(updates);
  }
