node-htmlencode

A wrapped version of http://www.strictly-software.com/htmlencode library -- only two changes to the original:

1. Renamed global Encoder object to module.exports so it can be used as a Node module.
2. Fixed leaking global variable arr in htmlDecode method

Usage

In addition to the very minor changes described above, the library is wrapped in a function to allow you to require just the individual method(s) you want.

var htmlencode = require('htmlencode');
htmlencode.htmlEncode('<h1>Welcome</h1>');
// &lt;h1&gt;Welcome&lt;/h1&gt;

works the same as

var htmlEncode = require('htmlencode').htmlEncode;
htmlEncode('<h1>Welcome</h1>');
// &lt;h1&gt;Welcome&lt;/h1&gt;

If you want to change to using numeric HTML entities, you'll still want to do something like this:

var htmlencode = require('htmlencode');
htmlencode.EncodeType = 'numerical'; // Don't blame me. I didn't name it.
htmlencode.htmlEncode('<h1>Welcome</h1>');
// &#60;h1&#62;Welcome&#60;/h1&#62;

Also provided is module.exports.Encoder, the wrapper class, so you can do something like this if you so choose:

var htmlencode = require('htmlencode');
var widget = new htmlencode.Encoder('numerical');
widget.htmlEncode('<h1>Welcome</h1>');
// &#60;h1&#62;Welcome&#60;/h1&#62;
