How to use EJS to template your Node.js application

Node.js developers often need to generate dynamic HTML documents server-side for web apps, and while native HTML and JavaScript concatenation can achieve this, they become cumbersome as complexity increases. Template engines like EJS (Embedded JavaScript Templating) provide a more efficient solution by allowing developers to use templates and data objects to produce HTML. EJS, popular among Node.js developers, integrates seamlessly with frameworks such as Express and Fastify, utilizing JavaScript for templating logic without the need for a new language. This engine supports features like shared templates and client-side support and offers a command-line interface for automation. The tutorial covers EJS setup, syntax, and advanced techniques, including using partials to create reusable views, as well as best practices and troubleshooting common errors. EJS's simplicity and use of native JavaScript and HTML make it accessible to beginners, setting it apart from alternatives like Pug and Handlebars, despite lacking some advanced features like template composition. The updated guide now includes a comprehensive introduction to EJS, installation instructions, expanded examples, and a comparison with other templating engines, enhancing its utility for developers.
