What is entities?

The 'entities' npm package is a library that helps with encoding and decoding HTML entities. It is useful for dealing with HTML data in text form and can be used to prevent XSS attacks by sanitizing input or output.

What are entities's main functionalities?

Encode HTML Entities

Encodes special characters in a string to their corresponding HTML entities. Useful for displaying text on a webpage without it being interpreted as HTML.

"require('entities').encodeHTML('<div>Hello & welcome!</div>');"

Decode HTML Entities

Decodes HTML entities back to their original characters. This is useful for processing text that contains HTML entities and converting them to their readable form.

"require('entities').decodeHTML('<div>Hello & welcome!</div>');"

Encode XML Entities

Similar to encoding HTML entities, but specifically for XML, which has a smaller set of entities.

"require('entities').encodeXML('<note>Priority & importance</note>');"

Decode XML Entities

Decodes XML entities back to their original characters, which is useful when working with XML data.

"require('entities').decodeXML('<note>Priority & importance</note>');"

README

#entities

En- & decoder for XML/HTML entities.

####Features:

• Focussed on speed
• Supports three levels of entities: XML, HTML4 & HTML5
  • Supports char code entities (eg. U)

##How to…

###…install entities

npm i entities

###…use entities

//encoding
require("entities").encode(<str> data[, <int> level]);
//decoding
require("entities").decode(<str> data[, <int> level]);

The level attribute indicates what level of entities should be decoded (0 = XML, 1 = HTML4 and 2 = HTML5). The default is 0 (read: XML).

There are also methods to access the level directly. Just append the name of the level to the action and you're ready to go (e.g. encodeHTML4(data), decodeXML(data)).
