更新Firebase-Storage映像

Question

有人可以向我解释如何使用firebase-storage / google-cloud-storage中的nodejs进行更新和映像吗？

我能够替换它，但我不知道如何更新它。

<h2>Client Profiles</h2>
<div class="add-client">
<label>Add new client</label>
<input placeholder="Client Name (required)" #clientProfileName />
<input placeholder="Client Address" #clientProfileAddress />
<button (click)="add(clientProfileName.value, clientProfileAddress.value); 
clientProfileName.value=''; clientProfileAddress.value=''">
    Add</button>
</div>
<ul class="clientProfiles">
<li *ngFor="let clientProfile of clientProfiles"
    [class.selected]="clientProfile === selectedClientProfile"
    (click)="onSelect(clientProfile)">
    <span class="badge">{{clientProfile.idnumber}}</span>
    <span>{{clientProfile.name}}</span>
    <button class="delete"
        (click)="delete(clientProfile); 
$event.stopPropagation()">Delete</button>
//delete button appears next to each client
</li>
</ul>
<div *ngIf="selectedClientProfile">
<h2>
    {{selectedClientProfile.name | uppercase}} selected
</h2>
<button (click)="gotoDetail()">View Details</button>
</div>
