<Avatar>

Universal avatar makes it possible to fetch/generate an avatar based on the information you have about that user. We use a fallback system that if for example an invalid Facebook ID is used it will try Google, and so on.

For the moment we support following types:

• Facebook
• Google
• GitHub
• Twitter (using Avatar Redirect)
• Instagram (using Avatar Redirect)
• Vkontakte (using Avatar Redirect)
• Skype
• Gravatar
• Custom image
• Name initials

The fallbacks are in the same order as the list above were Facebook has the highest priority.

Install

Install the component using NPM:

# besides React, react-avatar also has prop-types as peer dependency,
# make sure to install it into your project
$ npm install prop-types --save

Or download as ZIP.

Usage

1. Import Custom Element:

   import Avatar from 'react-avatar';

2. Start using it!

   <Avatar name="Foo Bar" />

Some examples:

<Avatar googleId="118096717852922241760" size="100" round={true} />
<Avatar facebookId="100008343750912" size="150" />
<Avatar githubHandle="sitebase" size={150} round="20px" />
<Avatar vkontakteId="1" size="150" />
<Avatar skypeId="sitebase" size="200" />
<Avatar twitterHandle="sitebase" size="40" />
<Avatar name="Wim Mostmans" size="150" />
<Avatar name="Wim Mostmans" size="150" textSizeRatio="1.75" />

<Avatar size="100" facebook-id="invalidfacebookusername" src="http://www.gravatar.com/avatar/a16a38cdfe8b2cbd38e8a56ab93238d3" />
<Avatar name="Wim Mostmans" unstyled="true" />

Avatar Redirect

Avatar Redirect adds support for social networks which require a server-side service to find the correct avatar URL.

Examples of this are:

• Twitter
• Instagram

An open Avatar Redirect endpoint is provided at https://avatar-redirect.appspot.com. However this endpoint is provided for free and as such an explicit opt-in is required as no guarantees can be made about uptime of this endpoint.

Avatar Redirect is enabled by setting the avatarRedirectUrl property on the ConfigProvider context

Development

In order to run it locally you'll need to fetch some dependencies and a basic server setup.

• Install local dependencies:

  $ npm install

• To test your react-avatar and your changes, start the development server and open http://localhost:8000/index.html.

  $ npm run dev

• To create a local production build into the lib and es folders.

  $ npm run build
