AvatarComponent

The Avatar component displays the provided image, with fallback to the first letter of the optional name input.

Basic Usage

A typical use case for the Avatar component would be to use in your custom components that will completely override a message component, or similar.

Example 1 - a basic example:

@Component({
  selector: "app-custom-message",
  template: `
    <stream-avatar [imageUrl]="imageUrl" [name]="name"></stream-avatar>
    <!-- Other parts of the custom message component -->
  `,
})
export class CustomMessageComponent {
  imageUrl =
    "https://pbs.twimg.com/profile_images/897621870069112832/dFGq6aiE_400x400.jpg";
  name = "Roy";
}

Customization

You can provide your own avatar component using the CustomTemplatesService

This will override the avatar for all locations (for example: message sender, channel preview). In case you want to override it only for selected locations, you can create a custom template like this:

<ng-template
  #avatarTemplate
  let-name="name"
  let-imageUrl="imageUrl"
  let-size="size"
  let-type="type"
  let-location="location"
  let-user="user"
  let-channel="channel"
  let-initialsType="initialsType"
  let-showOnlineIndicator="showOnlineIndicator"
>
  <my-custom-avatar
    *ngIf="location === 'message-sender'; else defaultAvatar"
  ></my-custom-avatar>
  <ng-template #defaultAvatar>
    <stream-avatar
      [name]="name"
      [imageUrl]="imageUrl"
      [size]="size"
      [type]="type"
      [location]="location"
      [user]="user"
      [channel]="channel"
      [initialsType]="initialsType"
      [showOnlineIndicator]="showOnlineIndicator"
    ></stream-avatar>
  </ng-template>
</ng-template>
