Fast html entities library.
Installation
------------
```bash
$ npm install html-entities
```
Usage
-----
**XML entities**
HTML validity and XSS attack prevention you can achieve from XmlEntities class.
```javascript
const Entities = require('html-entities').XmlEntities;
const entities = new Entities();
console.log(entities.encode('<>"\'&©®')); // &lt;&gt;&quot;&apos;&amp;©®
console.log(entities.encodeNonUTF('<>"\'&©®')); // &lt;&gt;&quot;&apos;&amp;&#169;&#174;
console.log(entities.encodeNonASCII('<>"\'&©®')); // <>"\'&©®
console.log(entities.decode('&lt;&gt;&quot;&apos;&amp;&copy;&reg;&#8710;')); // <>"'&&copy;&reg;
```
**All HTML entities encoding/decoding**
```javascript
const Entities = require('html-entities').AllHtmlEntities;
const entities = new Entities();
console.log(entities.encode('<>"&©®∆')); // &lt;&gt;&quot;&amp;&copy;&reg;
console.log(entities.encodeNonUTF('<>"&©®∆')); // &lt;&gt;&quot;&amp;&copy;&reg;&#8710;
console.log(entities.encodeNonASCII('<>"&©®∆')); // <>"&©®&#8710;
console.log(entities.decode('&lt;&gt;&quot;&amp;&copy;&reg;')); // <>"&©®
```
**Available classes**
```javascript
const XmlEntities = require('html-entities').XmlEntities, // <>"'& + &#...; decoding
Html4Entities = require('html-entities').Html4Entities, // HTML4 entities.
Html5Entities = require('html-entities').Html5Entities, // HTML5 entities.
AllHtmlEntities = require('html-entities').AllHtmlEntities; // Synonym for HTML5 entities.
```
Supports four methods for every class:
* encode — encodes, replacing characters to its entity representations. Ignores UTF characters with no entity representation.
* encodeNonUTF — encodes, replacing characters to its entity representations. Inserts numeric entities for UTF characters.
* encodeNonASCII — encodes, replacing only non-ASCII characters to its numeric entity representations.
* decode — decodes, replacing entities to characters. Unknown entities are left as is.
