Obtain the firebase object using Angular framework

Hey there, I've been working on retrieving a Firebase object using Angular and have successfully achieved that. However, I'm now faced with the challenge of how to navigate deeper into the data that is being returned (check out the images linked below).

Current output and My Firebase object structure

Here's the path I took to reach this point:

ClientService

getClientsOfThisBranch(branchNumber:string){
   return this.db.list('/clients/' + branchNumber).snapshotChanges();
}

SomeComponent

clientInfo$: any[] = [];

this.clientService.getClientsOfThisBranch('17').subscribe(data => {
   data.forEach(x => { console.log( x.payload.val() ); this.clientInfo$.push(x.payload.val())})
});

If anyone has insights or suggestions on how I can proceed further with this, I would really appreciate it. Thank you for your help!

Answer №1

Based on your question, it seems like you are aiming to transform the returned data into an array of client information objects. The data is currently in the form of an object with a client id containing client information. To achieve this, you can utilize the methods Object.keys() and Object.values() for deeper traversal.

clientData: any[];

this.clientService.fetchClientData('17').subscribe(response => {
  this.clientData = response.map(data => { 
    let obj = data.payload.val();
    let id = Object.keys(obj)[0];  // Assuming only one item based on provided image
    let info = Object.values(obj)[0];   // Assuming only one item based on provided image
    console.log(id, info);
  })
});

If there are multiple values, you can iterate through them accordingly.
