Universal avatar component for angular 2+ applications makes it possible to fetch / generate avatar from different sources

<ngx-avatar>

A universal avatar component for Angular 2+ applications that fetches / generates avatar based on the information you have about the user. The component has a fallback system that if for example an invalid Facebook ID is used it will try google ID and so on.

You can use this component whether you have a single source or a multiple avatar sources. In this case the fallback system will fetch the first valid avatar.

Moreover, the component can shows name initials or simple value as avatar.

Supported avatar sources:

• Facebook
• Google
• Twitter
• Vkontakte (VK)
• Skype
• Gravatar
• Github
• Custom image
• name initials
• value

The fallback system uses the same order as the above source list, Facebook has the highest priority, if it fails, google source will be used, and so on.

Once you have installed ngx-avatar, you can import it in your AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

// Import your AvatarModule
import { AvatarModule } from 'ngx-avatar';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    // Specify AvatarModule as an import
    AvatarModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

2. Start using it:

Once the AvatarModule is imported, you can start using the component in your Angular application:

The source object has the following properties:

• sourceId : identifier of the user
• getAvatar(size?) : method to fetch user avatar from the current source

Override Avatar Configuration

The avatar module provides the possibility of customizing the avatar component by overriding some of its options. For example, the avatar module comes with a set of default colors used to randomly fill the backgroud color of the avatar. Thus, it's possible to chnage the default list of colors and to pass your own list.

All you need to do is to configure the AvatarModule by calling forRoot method. The forRoot method takes an AvatarConfig Object that contains the overridden options.

At this moment, the AvatarConfig object has one parameter which is the avatarColors. In future releases, we will probably enrich this object to override more options ( such as the source priority )

Here's an example on how to import the AvatarModule with your own set of colors.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { UserService } from "./user.service";
import { AvatarModule,AvatarConfig } from "ngx-avatar";
import { HttpModule } from "@angular/http";

const avatarConfig = new AvatarConfig(['red','blue','pink']);

@NgModule({
  declarations: [
    AppComponent  ],
  imports: [
    BrowserModule,
    HttpModule,
    // import AvatarModule in your app with your own configuration
    AvatarModule.forRoot(avatarConfig)
  ],
  providers: [UserService],
  bootstrap: [AppComponent]
})
export class AppModule { }

Avatar Styling

In addition to the style attribute, ngx-avatar style can be customized using css classes. Thus, the generated code offers two css classes that can be overridden :

• avatar-container : class that represents the avatar container - the host element. Styles in this class will be applied on the avatar wether is an image or text.
• avatar-content : css class that represents the avatar element which is embedded inside the avatar-container.

To overcome Angular's view encapsulation, you may need to use the /deep/ operator to target it. Here's an example that shows how to override ngx-avatar style :

  <ngx-avatar class="my-avatar" value="HM"> </ngx-avatar>

Your css file might look like this

.my-avatar /deep/ .avatar-content {
    background-color : red !important;
}
