Server Side Rendering

This covers the fundamentals of building server-rendered applications across Flask, Django, and Express. You get working examples of template inheritance, custom filters, context processors, and caching strategies for Jinja2, Django templates, and EJS. The reference guides are split by framework, which is helpful if you're working in one ecosystem but might feel scattered if you're comparing approaches. The best practices section correctly emphasizes keeping business logic out of templates and caching expensive operations. It's solid for traditional web apps and SEO-critical pages, though the quick start example cuts off mid-implementation. Good breadth across Python and Node.js stacks.
