A universal avatar component for Angular 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.

![Angular Avatar component preview](https://cdn.rawgit.com/HaithemMosbahi/ngx-avatar/0bac9072/demo.png)

Supported avatar sources:

* Facebook
 * Google
 * Twitter
 * Instagram
 * 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.

If you enjoy watching videos, check out this [tutorial](https://medium.com/letsboot/lets-play-with-ngx-avatar-ec585dc39161) on medium which explains how to use ngx-avatar in your angular application.
 
 Check out this [link](https://stackblitz.com/edit/ngx-avatar-demo) to play with ngx-avatar :grinning:

## Installation

Install avatar component using [Yarn](https://yarnpkg.com/):

```bash
$ yarn add ngx-avatar
```

or

```bash
$ npm install ngx-avatar --save
```

## Usage

1. Import AvatarModule:

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

```typescript
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';

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

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

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

Starting from version 3.4.0:
- `HttpClientModule` is mandatory in order to fetch the avatar from external sources (Gravatar, Google, ...).

2. Start using it:

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

```html
<ngx-avatar></ngx-avatar>
```
## Examples

```html
<ngx-avatar facebookId="1508319875"></ngx-avatar>
<ngx-avatar googleId="1508319875"></ngx-avatar>
<ngx-avatar twitterId="1508319875"></ngx-avatar>
<ngx-avatar instagramId="dccomics" size="70"></ngx-avatar>
<ngx-avatar skypeId="1508319875"></ngx-avatar>
<ngx-avatar gravatarId="adde9b2b981a8083cf084c63ad86f753"></ngx-avatar>
<ngx-avatar gravatarId="user@gmail.com"></ngx-avatar>
<ngx-avatar src="assets/avatar.jpg"></ngx-avatar>
<ngx-avatar name="John Doe"></ngx-avatar>
<ngx-avatar value="75%"></ngx-avatar>

<ngx-avatar facebookId="userFacebookID" skypeId="userSkypeID"
 googleId="google" name="Haithem Mosbahi" src="assets/avatar.jpg"
 value="28%"  twitterId="twitter"
 gravatarId="adde9b2b981a8083cf084c63ad86f753" 
 size="100" [round]="true">
</ngx-avatar>

```

The source object has the following properties:
 * sourceType : avatar source ( Facebook, twitter, etc)
 * 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 background color of the avatar. Thus, it's possible to change 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.

AvatarConfig interface has two properties: 
  * **avatarColors:** allows the user to override the default avatar colors by providing a new set of colors
  * **sourcePriorityOrder:** allows the user to change the avatar source priority order. If you want the avatar component to look for user initials first, twitter before facebook or any order you want, this is can be done using the sourcePriorityOrder property

The following code shows an example on how to import the AvatarModule with your own source priority order. 
With the given order, the avatar component will look first for the custom avatar image and then for user initials and after that it will look the rest of sources.

```typescript
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from "@angular/common/http";

import { AppComponent } from './app.component';
import { UserService } from "./user.service";
import { AvatarModule, AvatarSource } from 'ngx-avatar';

const avatarSourcesOrder = [AvatarSource.CUSTOM, AvatarSource.INITIALS];

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

```

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

* Starting from version 3.1, overriding the avatar configuration can be done as follows:

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

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

const avatarColors = ["#FFB6C1", "#2c3e50", "#95a5a6", "#f39c12", "#1abc9c"];

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

```

* Users who use a prior version of ngx-avatar ( < 3.1 ) can override the configuration as follows:

```typescript
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 { HttpClientModule } from "@angular/common/http";

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

@NgModule({
  declarations: [
    AppComponent  ],
  imports: [
    BrowserModule,
    HttpClientModule,
    // 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 whether 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 : 
 
 ```html
   <ngx-avatar class="my-avatar" value="HM"> </ngx-avatar>
 ```
 Your css file might look like this 
 
 ```css
 .my-avatar /deep/ .avatar-content {
     background-color : red !important;
 }
 ```
