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:
- GitHub
- Google (using Avatar Redirect)
- 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 the component using NPM:
$ npm install react-avatar --save
# 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.
Users of Gatsby who are experiencing issues with the latest release should install react-avatar@corejs2
instead. This is an older version (v3.7.0) release of react-avatar
that still used core-js@2
.
If you'd like to use the latest version of react-avatar
have a look at #187 for a workaround and #187, #181 and #198 for a description of the issue.
-
Import Custom Element:
import Avatar from 'react-avatar';
-
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 value="86%" size="40" />
<Avatar size="100" facebook-id="invalidfacebookusername" src="https://www.gravatar.com/avatar/a16a38cdfe8b2cbd38e8a56ab93238d3" />
<Avatar name="Wim Mostmans" unstyled={true} />
Manually generating a color:
import Avatar from 'react-avatar';
<Avatar color={Avatar.getRandomColor('sitebase', ['red', 'green', 'blue'])} name="Wim Mostmans" />
Configuring React Avatar globally
import Avatar, { ConfigProvider } from 'react-avatar';
<ConfigProvider colors={['red', 'green', 'blue']}>
<YourApp>
...
<Avatar name="Wim Mostmans" />

// Keep a maximum of 20 entries in the source cache
sourceSize: 20
});
// Apply cache globally

Avatar Redirect adds support for social networks which require a server-side service to find the correct avatar URL.
Examples of this are:
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
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
https://localhost:8000/index.html
.$ npm run dev
-
To create a local production build into the
lib
andes
folders.$ npm run build
cache
as provided to the ConfigProvider
should be an object implementing the methods below. The default cache implementation can be found here
Method | Description |
---|---|
set(key, value) |
Save value at key , such that it can be retrieved using get(key) . Returns undefined |
get(key) |
Retrieve the value stored at key , if the cache does not contain a value for key return null |
sourceFailed(source) |
Mark the image URL specified in source as failed. Returns undefined |
hasSourceFailedBefore(source) |
Returns true if the source has been tagged as failed using sourceFailed(source) , otherwise false . |
When using webpack 4 you can rely on tree shaking to drop unused sources when creating your Avatar component like the example below.
import { createAvatarComponent, TwitterSource } from 'react-avatar';
const Avatar = createAvatarComponent({
sources: [ TwitterSource ]
});
Exported sources:
- GravatarSource
- FacebookSource
- GithubSource
- SkypeSource
- ValueSource
- SrcSource
- IconSource
- VKontakteSource
- InstagramSource
- TwitterSource
- GoogleSource
- RedirectSource
If you are using a version of webpack that does not support tree shaking or are using a different bundler you'll need to import only those files you need.
import createAvatarComponent from 'react-avatar/es/avatar';
import TwitterSource from 'react-avatar/es/sources/Twitter';
const Avatar = createAvatarComponent({
sources: [ TwitterSource ]
});
const createAvatarComponent = require('react-avatar/lib/avatar').default;
const TwitterSource = require('react-avatar/lib/sources/Twitter').default;
const Avatar = createAvatarComponent({
sources: [ TwitterSource ]
});
