SvgAvatar

by Gabriel Franck

SvgAvatar is a javascript module assembling different svg object to create an avatar. This will allow us to not store svg files or images of avatars but just the index of each part.

SvgAvatar will be designed to support custom librairies of avatars, a tutorial will be coming soon.

If you want to use it with AngularJs please consider svg_avatar_angularjs

Installation

Install it via npm :

npm install svg_avatar

Or via bower :

bower install svg_avatar

If you are in a NodeJS environement, you just need to include svgAvatar to your javascript project :

svgAvatar = require('svg_avatar')

If you're not, include the bundle.js before the files where you're going to use SvgAvatar :

<script src="bower_components/svg_avatar/bundle.js"></script>
or
<script src="node_modules/svg_avatar/bundle.js"></script>

and then you can :

svgAvatar = require('svg_avatar')
