What is a .njk file?

Nunjucks is a powerful templating engine for JavaScript, heavily inspired by Jinja2 (Python). Files with the .njk extension are Nunjucks template files. These files contain a mix of HTML (or other markup languages), CSS, JavaScript, and Nunjucks-specific syntax. This syntax allows developers to embed dynamic content, such as variables, loops, and conditional statements, directly into the template. When the template is processed by the Nunjucks engine, these dynamic elements are evaluated and replaced with their corresponding values, resulting in a final output file (typically HTML) that is ready to be served to a user's browser. Nunjucks templates are commonly used in web development to generate dynamic web pages, emails, and other types of content. They promote code reusability and separation of concerns by allowing developers to separate the presentation logic from the application logic. The engine supports features like template inheritance, auto-escaping, and custom filters, making it a versatile tool for building complex web applications. Nunjucks is often used with Node.js but can also be used in the browser.
