Back in April this year I came across this post by Josh Farrant detailing how to add support to any website for Unicode Emoji characters with twemoji and given the sad state of emoji support in popular browsers at present having a cross-browser polyfill available for the time being is a good thing. However, when writing posts I tend to use sublime text or nano via remote shell and in neither case do I have access to Unicode emoji input so I bookmarked Josh's post and largely forgot about it.
Last week while researching in browser markdown editors I discovered markdown-editor by James Taylor and upon viewing the projects online demo and seeing an emoji in the preview I had wondered if it was the same method that Josh had documented on his blog. After a quick browse of the source code I soon discovered that James is using another library called emojify.js by Hassan Khan and the library converts Emoji keywords to images rather than the Unicode characters.
With emoji.js you can the text
:+1: within your page and emoji.js will convert it to :+1: by using the following code:
By default emoji.js will not convert the content of
code tags so you do not need to worry that installing it will unintentionally break things and you can pass in a DOM element to emojify's
run method to limit the area that it targets like so:
I would not recommend the over use of emojis on any website, however they can in certain cases add additional meaning or emphasis to a body of text and if nothing else do add a certain degree of fun to the page and with libraries such as emoji.js and twemoji there is now tools available to bring them to your website.
It would be nice if there were one library that did both... ↩︎
