What is the best way to dynamically retrieve Firebase data within an HTML template?

My Firebase real-time database contains two data objects: Tweets and Users. Each tweet object includes a property called userid. I want to retrieve the user's name associated with each tweet.

Currently, I am attempting to achieve this with the following code:

<ion-item *ngFor="let tweet of tweets| async" >
{{(af.database.object('/Users/'+tweet.userid+'/name') | async)}}
</ion-item>

This code successfully retrieves the JSON data, but I am having trouble extracting just the value. When I attempt to debug using the |json pipe:

<ion-item *ngFor="let tweet of tweets| async" >
{{(af.database.object('/Users/'+tweet.userid+'/name') | async | json)}} 
</ion-item>

I can see the following JSON output:

{
  "$value": "username",
  "$key": "name"
}

However, my desired output is simply the username. How do I extract only that value?

Answer №1

Check out this code snippet:

<ion-item *ngFor="let tweet of tweets| async" >
{{(af.database.object('/Users/'+tweet.userid+'/name') | async)?.$value}} 
</ion-item>
