# html-escape

Escape a string to be safe for use in html. `&`, `<`, `'`, and `"`
characters are replaced with with their [named character references][]:
`&amp;`, `&lt;`, `&apos;`, and `&quot;`. Escaped strings will be safe
for use in the following contexts:

 * [RCDATA][] and [DATA][html-data] (content of all elements except for
   `<script>` and `<style>`)
 * [Single-quoted attribute values][html-single-attribute] `'`
 * [Double-quoted attribute values][html-double-attribute] `"`

[named character references]: https://html.spec.whatwg.org/multipage/syntax.html#named-character-references
[html-data]: https://html.spec.whatwg.org/multipage/syntax.html#data-state
[rcdata]: https://html.spec.whatwg.org/multipage/syntax.html#rcdata-state
[html-single-attribute]: https://html.spec.whatwg.org/multipage/syntax.html#attribute-value-(single-quoted)-state
[html-double-attribute]: https://html.spec.whatwg.org/multipage/syntax.html#attribute-value-(double-quoted)-state

# Example

```js
var escape = require("html-escape");
var xssAttempt = "Hello <script>while(1);</script> world!";
// Output safe html
console.log("<p>" + escape(xssAttempt) + "</p>");
// "<p>Hello &lt;script>while(1);&lt;/script> world!</p>"
```

# Installation

```
npm install html-escape
```
