html-entities

Fastest HTML entities library.

Comes with both TypeScript and Flow types.

Installation

$ npm install html-entities

Usage

encode(text, options)

Encodes text replacing HTML special characters (<>&"') and/or other character ranges depending on mode option value.

import {encode} from 'html-entities';

encode('< > " \' & © ∆');
// -> '&lt; &gt; &quot; &apos; &amp; © ∆'

encode('< ©', {mode: 'nonAsciiPrintable'});
// -> '&lt; &copy;'

encode('< ©', {mode: 'nonAsciiPrintable', level: 'xml'});
// -> '&lt; &#169;'

encode('< > " \' & ©', {mode: 'nonAsciiPrintableOnly', level: 'xml'});
// -> '< > " \' & &#169;'

Options:

level

• all alias to html5 (default).
• html5 uses HTML5 named references.
• html4 uses HTML4 named references.
• xml uses XML named references.

mode

• specialChars encodes only HTML special characters (default).
• nonAscii encodes HTML special characters and everything outside the ASCII character range.
• nonAsciiPrintable encodes HTML special characters and everything outiside of the ASCII printable characters.
• nonAsciiPrintableOnly everything outiside of the ASCII printable characters keeping HTML special characters intact.
• extensive encodes all non-printable characters, non-ASCII characters and all characters with named references.

numeric

• decimal uses decimal numbers when encoding html entities. i.e. © (default).
• hexadecimal uses hexadecimal numbers when encoding html entities. i.e. ©.

decode(text, options)

Decodes text replacing entities to characters. Unknown entities are left as is.

import {decode} from 'html-entities';

decode('< > " ' & © ∆');
// -> '< > " \' & © ∆'

decode('&copy;', {level: 'html5'});
// -> '©'

decode('&copy;', {level: 'xml'});
// -> '&copy;'

Options:

level

• all alias to html5 (default).
• html5 uses HTML5 named references.
• html4 uses HTML4 named references.
• xml uses XML named references.

scope

• body emulates behavior of browser when parsing tag bodies: entities without semicolon are also replaced (default).
• attribute emulates behavior of browser when parsing tag attributes: entities without semicolon are replaced when not followed by equality sign =.
• strict ignores entities without semicolon.

decodeEntity(text, options)

Decodes a single HTML entity. Unknown entitiy is left as is.

import {decodeEntity} from 'html-entities';

decodeEntity('<');
// -> '<'

decodeEntity('&copy;', {level: 'html5'});
// -> '©'

decodeEntity('&copy;', {level: 'xml'});
// -> '&copy;'

Options:

level

• all alias to html5 (default).
• html5 uses HTML5 named references.
• html4 uses HTML4 named references.
• xml uses XML named references.
