roopakv/node-emoji

simple emoji support for node.js projects

Note: This is a clone of node-emoji, with support for latest emoji.

Installation

To install roopakv/node-emoji, you need node.js and npm. :rocket:

Once you have that set-up, just run npm install --save roopakv/node-emoji in your project directory. :ship:

You're now ready to use emoji in your node projects! Awesome! :metal:

Usage

var emoji = require('roopakv/node-emoji')
emoji.get('coffee') // returns the emoji code for coffee (displays emoji on terminals that support it)
emoji.which(emoji.get('coffee')) // returns the string "coffee"
emoji.get(':fast_forward:') // `.get` also supports github flavored markdown emoji (http://www.emoji-cheat-sheet.com/)
emoji.emojify('I :heart: :coffee:!') // replaces all :emoji: with the actual emoji, in this case: returns "I ❤️ ☕️!"
emoji.random() // returns a random emoji + key, e.g. `{ emoji: '❤️', key: 'heart' }`
emoji.search('cof') // returns an array of objects with matching emoji's. `[{ emoji: '☕️', key: 'coffee' }, { emoji: ⚰', key: 'coffin'}]`
emoji.unemojify('I ❤️ 🍕') // replaces the actual emoji with :emoji:, in this case: returns "I :heart: :pizza:"
emoji.find('🍕') // Find the `pizza` emoji, and returns `({ emoji: '🍕', key: 'pizza' })`;
emoji.find('pizza') // Find the `pizza` emoji, and returns `({ emoji: '🍕', key: 'pizza' })`;
emoji.hasEmoji('🍕') // Validate if this library knows an emoji like `🍕`
emoji.hasEmoji('pizza') // Validate if this library knowns a emoji with the name `pizza`
emoji.strip('⚠️ 〰️ 〰️ low disk space') // Strips the string from emoji's, in this case returns: "low disk space".
emoji.replace('⚠️ 〰️ 〰️ low disk space', (emoji) => `${emoji.key}:`) // Replace emoji's by callback method: "warning: low disk space"

Options

onMissing

emoji.emojify(str, onMissing)

As second argument, emojify takes an handler to parse unknown emojis. Provide a function to add your own handler:

var onMissing = function (name) {
  return name;
});

var emojified = emoji.emojify('I :unknown_emoji: :star: :another_one:', onMissing);
// emojified: I unknown_emoji ⭐️ another_one

format

emoji.emojify(str, onMissing, format)

As third argument, emojify takes an handler to wrap parsed emojis. Provide a function to place emojis in custom elements, and to apply your custom styling:

var format = function (code, name) {
  return '<img alt="' + code + '" src="' + name + '.png" />';
});

var emojified = emoji.emojify('I :unknown_emoji: :star: :another_one:', null, format);
// emojified: I <img alt="❤️" src="heart.png" /> <img alt="☕️" src="coffee.png" />

Adding new emoji

Emoji come from js-emoji (Thanks a lot :thumbsup:). You can get a JSON file with all emoji here: https://raw.githubusercontent.com/omnidan/node-emoji/master/lib/emoji.json

To update the list or add custom emoji, clone this repository and put them into lib/emojifile.js. Then run npm run-script emojiparse in the project directory or node emojiparse in the lib directory. This should generate the new emoji.json file and output Done..

That's all, you now have more emoji you can use! :clap:
