Closure Templates

Overview:

Closure Templates are a client- and server-side templating system that allows programmers to dynamically build reusable HTML and UI elements. Unlike traditional templating systems, Closure Templates allow for the creation of small components that can be composed to form a user interface. They are implemented for both JavaScript and Java, making them versatile for use on both the server and client side.

Features:

• Convenience: Closure Templates provide an easy way to build HTML for application UI and help separate application logic from display.
• Language-neutral: Closure Templates work with both JavaScript and Java, allowing for the sharing of templates between client and server side.
• Client-side speed: Templates are compiled into efficient JavaScript functions for optimal performance on the client side.
• Easy to read: The structure of the template code reflects the structure of the output HTML, making it easily readable. Messages for translation are inline for improved readability.
• Designed for programmers: Templates are functions that can call each other, with a syntax familiar to programmers. Multiple templates can be placed in one source file.
• Tool, not a framework: Closure Templates can be used in any web application environment, alongside other libraries, frameworks, or tools.
• Battle-tested: Closure Templates are extensively used in major web applications like Gmail and Google Docs.
• Secure: Closure Templates are contextually autoescaped to reduce the risk of cross-site scripting (XSS) attacks.

Summary:

Closure Templates provide a convenient, language-neutral, and efficient solution for building reusable HTML and UI elements. They are designed for programmers and offer easy readability and security. Although staffing for open source support is limited, Closure Templates have been extensively used in major web applications and have integrations with popular open source frameworks.
