emoji-translator.js

A JavaScript library that translates English into emoji.

Also contains a helper data file with a recent list of Unicode codepoints for all emoji, their names and associated keywords.

How to use the library

The library provides its functionality via a Translator class, which can be instantiated by passing it the json emoji data object from emoji_data.json.

Once you have an initialized Translator, you can use its translate method to get an emojified version of your text.

// Load emoji-translator.js, which exports a constructor for Translator.
var emojiData = myFunctionToLoadData('emoji_data.json');
var translator = new Translator(emojiData);
translator.translate("I love emoji almost as much as cats. Oh joy!");
// Returns: "I 💖 emoji almost as much as 😸. Oh 😂!"

How it works

The current translation implementation looks up words from the input text in a table of words to emoji unicode codepoints.

If an input word matches more than one emoji in the list, a random matching emoji is returned. So, for example, "cat" might return different cat emojis on each call.

The table of emoji names and synonyms is created semi-automatically by parsing the Unicode website, and adding synonyms and associated concepts by hand. The utilities used to do this work can be found in the data-utils directory of this repository.
