Avatar

Avatar is a JavaScript library for showing Gravatars or generating user avatars.

Examples

There are several examples on the website.

import Avatar from 'avatar-initials';
// or
const Avatar = require('avatar-initials')

// Add an avatar to an <img>
const avatar = Avatar.from(document.getElementById('avatar'), {
  'useGravatar': false,
  'initials': 'MC',
});

// If you just want the URL / string:
const github_avatar_url = Avatar.githubAvatar({
  id: '12345'
});

const gravatar_url_from_email = Avatar.gravatarUrl({
  email: '[email protected]'
});

const gravatar_url_from_hash = Avatar.gravatarUrl({
  hash: '12929016fffb0b3af98bc440acf0bfe2'
});

const initial_png = Avatar.initialAvatar({
  initials: 'MC',
  initial_fg: '#888888',
  initial_bg: '#f4f6f7',
  initial_size: 0, // Defaults to height / 2
  initial_weight: 100,
  initial_font_family: "'Lato', 'Lato-Regular', 'Helvetica Neue'",
});

This example will render an avatar with my initials "MC" as the image.

Options

Avatar is highly customizable and most options are self explanatory:

{
  useGravatar: true,       // Allow Gravatars or not.
  fallbackImage: '',       // URL or Data URI used when no initials are provided and not using Gravatars.
  size: 80,                // Size in pixels, fallback for hidden images and Gravatar
  setSourceCallback: null, // Callback called when image source is set (useful to cache avatar sources provided by third parties such as Gravatar)

  // Initial Avatars Specific
  initials: '',          // Initials to be used.
  initial_fg: '#888888', // Text Color
  initial_bg: '#f4f6f7', // Background Color
  initial_size: 0,       // Text Size in pixels
  initial_weight: 100,   // Font weight (numeric value for light, bold, etc.)
  initial_font_family: "'Lato', 'Lato-Regular', 'Helvetica Neue'",

  // Gravatar Specific
  hash: '',                     // Precalculated MD5 string of an email address
  email: '',                    // Email used for the Gravatar
  fallback: 'mm',               // Fallback Type
  rating: 'x',                  // Gravatar Rating
  forcedefault: false,          // Force Gravatar Defaults
  allowGravatarFallback: false, // Use Gravatars fallback, not fallbackImage

  // GitHub Specific
  github_id: null,  // GitHub User ID.
}

jQuery Support

if (typeof jQuery !== 'undefined') {
  jQuery.fn.avatar = function avatar(options) {
    return this.each(() => {
      /* istanbul ignore else */
      if (!jQuery.data(this, 'plugin_avatar')) {
        jQuery.data(this, 'plugin_avatar', new Avatar(this, options));
      }
    });
  };
}
