API

$3

This works in the browser and on Node

#### Parameters

- object - Optional JSON object with any of the following attributes:

Option | Default | Description
--- | --- | ---
blacklist.elements | ['script', 'textarea', 'a', 'pre', 'code'] | An array of elements you don't want emojified
blacklist.classes | ['no-emojify'] | An array of classes you don't want emojified
mode | img | By default, emojify will output an img with a src attribute for each emoji found. But if mode is set to sprite or data-uri, then spans with classes are outputted. Don't forget to include the appropriate CSS for your choice though, see the /dist directory.
tag_type | null | When set, emojify uses this element with the class emoji emoji-#{emojiname} instead of an img with a src attribute. Example valid values: div, span. This takes precedence over the mode option. Note: if you're not using imgs, .emoji-+1 isn't a valid class, so .emoji-plus1 is used instead.
only_crawl_id | null | [DEPRECATED] Restricts searching for emojis to a specified element & it's children. If null, and no object is passed to run(), document.body is used
img_dir | 'images/emoji' | Defines the path to the emoji images
ignore_emoticons | false | If true, only convert emoji like :smile: and ignore emoticons like :)

#### Usage
``js
emojify.setConfig({tag_type : 'div'});
`

#### Parameters
- element - Optional HTML element to restrict the emojification to.
- replacer - Optional Function to override emoji replacement behaviour with your own. The function will receive two arguments, the emoji pattern found (emoji), and the emoji name (name). In the case of emoticons, for example, emoji = ':)' and name = 'smile'. Your function must return a HTMLElement.


##### Browser
`js
emojify.run();
// OR
emojify.run(document.getElementById('my-element'))
// OR
emojify.run(null, function(emoji, emojiName){
var span = document.createElement('span');
span.className = 'emoji emoji-' + emojiName;
span.innerHTML = emoji + ' replaced';
return span;
});
`

##### Node.js
Requires you to have jsdom installed:
npm i jsdom --save

`js
var jsdom = require('jsdom')

jsdom.env({
html: "

jhhh:)

",
done: function(errors, window) {
emojify.run(window.document.body)
}
});
`

#### Parameters
- string - String to emojify
- callback - Optional callback function to output emoji with

#### Usage

By default, emojify.js uses the internal function defaultReplacer() to replace emoji. You can override this behaviour by supplying your own callback function.

Your callback function will receive two arguments, the emoji pattern found (emoji), and the emoji name (name). In the case of emoticons, for example, emoji = ':)' and name = 'smile'.

The context in which your replacer function is run will have the config available. So you can access properties such as img_dir at this.config.img_dir.

`js
emojify.replace('I am happy :)');
// OR
replacer = function(emoji, name) {
// Customise output here
return emojifiedString;
}

emojify.replace('I am happy :)', replacer);
``
