Emojis

This little package has a function (two actually) for replacing emoji codes (like :smiley:) for emoji images (or unicode characters) in a given string. Similar to GitHub and other websites.

Usage

$ npm install emojis
emojis@1.0.6 node_modules/emojis
$ node
> var emojis = require('emojis')
undefined
> emojis.replaceWithUnicode('I :heart: you!')
'I ❤️ you!'
> emojis.replaceWithHtml('I :heart: you!', 'http://example.org/images/')
'I <img class="emoji" width="20" height="20" src="http://example.org/images/heart.png" alt="heart"> you!'

Emoji codes and images

The emoji codes used are the ones on Emoji cheat sheet.

Their images are also provided here for you to use (images.zip), but consider their copyright.

Aligning the HTML image

One way to align the emoji image within the text would be using align="absmiddle", just as GitHub does, but I didn't do it because it's obsolete.

A suggestion is to use the following CSS:

.emoji {
  margin-bottom: .25em;
  vertical-align: middle;
}
