templatingteknologiat

Templatingteknologiat, also known as templating engines and template languages, are software components that generate text output by combining predefined templates with data at render time. They are used to produce dynamic HTML, emails, configuration files, or code, while keeping presentation separate from business logic.

Templates consist of static text and placeholders or expressions that are replaced with data. They may include control structures such as conditionals and loops, and often support helpers, filters, or formatting functions. They can use escaping to prevent injection attacks. Most templating systems distinguish between logic inside templates and data provided by applications, though some are more logic-heavy than others.

Templatingtechnologies fall into client-side (in the browser) and server-side categories. Client-side templates render in the user’s browser, enabling dynamic updates without full page reloads. Server-side templates are rendered on the server and sent as final HTML.

Common features include partials or includes (reusing template fragments), template inheritance or layout, and the ability to extend templates with custom functions.

Examples include Mustache and Handlebars (logic-less), EJS, Pug, Twig, Jinja2, Liquid, and Freemarker, spanning JavaScript, Python, PHP, Ruby, and Java ecosystems.

Templatingteknologiat are widely used in web development, content management, and report generation. When choosing one, developers consider language ecosystem, syntax, performance, security features, and community support.
