Latte, Nette's built-in templating engine, redefines simplicity and security in PHP web development. Unlike traditional templating systems, Latte compiles templates into optimized PHP code, boosting performance and caching efficiency. Its intuitive syntax, with clever macros embedded in HTML tags, makes templates highly readable compared to native PHP or engines like Smarty. Latte's standout feature is its automatic protection against XSS attacks through Context-Aware Escaping, ensuring variables are safely rendered by default. This reduces developer errors and enhances application security. Supporting HTML5, AJAX, and internationalization, Latte is versatile for building dynamic, multilingual interfaces. Praised for its ease of use and speed, Latte is a key reason developers love Nette, offering a seamless blend of power and simplicity for crafting secure, modern web applications.
