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.get('heart') //❤️
emoji.get(':)') //😄
emoji.emojify('I :heart: :coffee:!') // replaces all :emoji: with the actual emoji, in this case: returns "I ❤️ ☕️!"
emoji.emojify(":-) :* <3 ^_^ >:o (y) -_- :smile: ;) :P O:) :/ :'( 3:)") // replace almost all shorthand emoji support 😄 😘 ❤️ 😙 😆 👍 😑 😄 😉 😛 👼 😕 😢 😈
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);
