Source

<Avatar> Build Status npm downloads version npm bundle size (minified + gzip) npm type definitions

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.

React Avatar component preview

For the moment we support following types:

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

Demo

Check it live!

Install

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.

Note on usage in Gatsby projects

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.

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 value="86%" size="40" />
<Avatar size="100" facebook-id="invalidfacebookusername" src="http://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" />
        ...
    </YourApp>
</ConfigProvider>

ConfigProvider

AttributeOptionsDefaultDescription
colorsarray(string)default colorsA list of color values as strings from which the getRandomColor picks one at random.
cachecacheinternal cacheCache implementation used to track broken img URLs
initialsfunctiondefaultInitialsA function that derives the initials from the component props, the method should have the signature fn(name, props)
avatarRedirectUrlURLundefinedBase URL to a Avatar Redirect instance

Example

import Avatar, { ConfigProvider } from 'react-avatar';

<ConfigProvider colors={['red', 'green', 'blue']}>
    <YourApp>
        ...
        <Avatar name="Wim Mostmans" />
        ...
    </YourApp>
</ConfigProvider>

Cache

This class represents the default implementation of the cache used by react-avatar.

Looking to implement more complex custom cache behaviour?

AttributeOptionsDefaultDescription
cachePrefixstringreact-avatar/The prefix for localStorage keys used by the cache.
sourceTTLnumber604800000 (7 days)The amount of time a failed source is kept in cache. (in milliseconds)
sourceSizenumber20The maximum number of failed source entries to keep in cache at any time.

usage

import Avatar, { Cache, ConfigProvider } from 'react-avatar';

const cache = new Cache({

    // Keep cached source failures for up to 7 days
    sourceTTL: 7 * 24 * 3600 * 1000,

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

// Apply cache globally
<ConfigProvider cache={cache}>
    <YourApp>
        ...
        <Avatar name="Wim Mostmans" />
        ...
    </YourApp>
</ConfigProvider>

// For specific instances
<Avatar name="Wim Mostmans" cache={cache} />

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
    

Implementing a custom cache

cache as provided to the ConfigProvider should be an object implementing the methods below. The default cache implementation can be found here

MethodDescription
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.

Reducing bundle size

Webpack 4

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

Without Webpack >= 4

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.

ES6 modules
import createAvatarComponent from 'react-avatar/es/avatar';
import TwitterSource from 'react-avatar/es/sources/Twitter';

const Avatar = createAvatarComponent({
    sources: [ TwitterSource ]
});
Transpiled ES5 javascript / commonjs
const createAvatarComponent = require('react-avatar/lib/avatar').default;
const TwitterSource = require('react-avatar/lib/sources/Twitter').default;

const Avatar = createAvatarComponent({
    sources: [ TwitterSource ]
});
