What is the best way to fetch a list of users from a Firebase database using angularFire without using a "key"?

I'm currently utilizing angularFire to establish a connection between my web page and my database. My objective is to showcase all the users saved in my firebase database in a list format on a specific page. The users are stored in the following manner based on their email:

users
   |_email:name
   |   
   |_email:name
   |
   |_email:name
   |
   |_...

The issue I am encountering is that I am unsure of how to retrieve all the users and place them into an Array.

It seems like it might be related to using .list(), but with this function, I would need to categorize users differently, for example:

user
   |_key1
   |   |_email:value
   |   |_name:value
   |_key2
   |   |_email:value
   |   |_name:value
   |_...

I aim to store this information in my credentialsArray utilizing the Credential model, so that I can display it within a table:

this.credentialsArray.push(new Credential('name', 'email'));

This organization helps me list it out as follows:

<tr *ngFor="let item of credentialsArray">
   <td>{{ item.name }}</td>
   <td>{{ item.email }}</td>
</tr>

Any guidance on how I can accomplish this task?

Answer №1

To populate an array with values retrieved from the 'user' list, you can utilize a loop method as demonstrated below:

this.fireDB.list('user').snapshotChanges().subscribe(res => {

        res.forEach(doc => {

        this.credentialsArray.push(doc.payload.val());

    });

});

After implementing this code, your HTML content should successfully display the results.
