Discord looks up the emoji in my listfinds the one with the name ayy and looks up its ID. This is the code that makes up the emoji. This ID is unique to each emoji. There are two places where you can grab emojis using discord. If you've learned anything from Understanding Collectionsyou might already know how to get something by ID from a collection:. You might also know how to use find to get something with another property - so here, I can get ayy through its name:.

But how does one output that emoji to the chat? Well, just like users and roles, emojis have a special. So, ayy. You can also take advantage of concatenation and template literals to simplify the task, since they will automatically do the conversion for you:.

First, a quick dive into the inner workings of Unicode, followed by how emoji in particular are represented in JavaScript. If your eyes glaze over like mine did while reading this, I put all the code into an npm library you can find here. Sad sack A. The letter A is represented by the code point 65 in decimalor 41 in hexadecimal.

A few things to note about hexadecimal representation in Javascript:. Originally, the range of code points was 16 bits, which encompassed the English alphabet now known as the Basic Multilingual Plane. Now, in addition to that original range, there are 16 more planes 17 total to choose from. Emoji live on Plane 1, the Supplementary Multilingual Plane.

In Javascript, a string is a sequence of bit code points. Since emoji are encoded above the BMP, it means that they are represented by a pair of code points, also known as a surrogate pair.

The first pair is called the lead surrogateand the latter the tail surrogate. Javascript interprets this pair of characters as having a length of 2.

So, how do we get the surrogate pair? Because of these limitations within Javascript, in order to parse strings containing emoji, we need some fancy footwork. Luckily, the internet is awash in smarter folks than I. The lodash library has produced a rock solid emoji regular expression. Is is:.

Our audience uses the English alphabet over SMS, so tough luck if I trawl up any other unsuspecting characters. Holy camoley, what the heck are those?

Is it perfect? Of course not. It might not even be better. But it's definitely different and has few advantages.

The only thing I found to be slightly difficult was to map emojis to actual JavaScript objects and events.

It took a lot of time, but once the mapping is done everything else is a breeze. There are emojis. To avoid making thousands of HTTP requests, all of them are stored in a single file called a sprite sheet or image atlas. Here is a partial view of the official Twitter emoji sprite sheet:.

The official Twitter emoji sprite sheet image is even bigger than this. The idea behind a sprite sheet is to store all emojis in one file, thus needing only one HTTP request from the server instead of hundreds. Or thousands in this case because there are Twitter emojis as of March 17, Each individual emoji is then displayed in a single DIV element and can be navigated to by changing this property:.

By supplying this property with an x and y offset in pixels we can navigate to any Emoji in the set.

We just need to memorize the position of each emoji and store it in a JavaScript object. I started with rebuilding the emoji tabs interface. There are more specifically meaningful subject groups than the 9 tabs Twitter offers — NatureCarsAirplanesTrains — it could be more specific.

One thing of importance here is that I added the custom attributes data-type and data-title. Like their names suggest, data-type holds the tab name that will be used later to filter the emojis, and data-title stores a simple description of each set. I separated positive and negative emojis.

It basically shows the entire set as an image. Clicking on it with a mouse will yield an x and y background offset to that emoji in the developer console.From its humble beginnings inEmojis are all the rage these days.
