Thymeleaf
# Thymeleaf

Thymeleaf is a Java XML/XHTML/HTML5 template engine that can work both in web (servlet-based) and non-web environments. It is better suited for serving XHTML/HTML5 at the view layer of MVC-based web applications, but it can process any XML file even in offline environments. It provides full Spring Framework integration.

In web applications Thymeleaf aims to be a complete substitute for JavaServer Pages (JSP), and implements the concept of Natural Templates: template files that can be directly opened in browsers and that still display correctly as web pages.

Thymeleaf is open-source software, licensed under the Apache License 2.0.

## Features

From the project's website:

* Java template engine for XML, XHTML and HTML5.
* Works both in web and non-web (offline) environments. No hard dependency on the Servlet API.
* Based on modular feature sets called dialects.
   * Dialect features (e.g.: evaluation, iteration, etc.) are applied by linking them to template's tags and/or attributes.
   * Two dialects available out-of-the-box: Standard and SpringStandard (for Spring MVC apps, same syntax as Standard).
   * Developers can extend and create custom dialects.
* Several template modes:
   * XML: validating against a DTD or not.
   * XHTML 1.0 and 1.1: validating against standard DTDs or not.
   * HTML5: both XML-formed code and legacy-based HTML5. Legacy non-XML code will be automatically cleaned and converted to XML form.
* Full (and extensible) internationalization support.
* Configurable, high performance parsed template cache that reduces input/output to the minimum.
* Automatic DOCTYPE translations –from template DTD to result DTD– for (optional) validation of both template and result code.
* Extremely extensible: can be used as a template engine framework if needed.
* Complete documentation including several example applications.

## Thymeleaf example

The following example produces an HTML5 table with rows for each item of a List<Product> variable called allProducts.

This piece of code includes:

* Internationalization expressions: #{ ... } rh
* Variable/model-attribute evaluation expressions: ${ ... }
* Utility functions: #numbers.formatDecimal( ... )

Also, this fragment of (X)HTML code can be perfectly displayed by a browser as a prototype, without being processed at all: it is a natural template.
