Backend Frameworks
intermediateTopic 8 of 12 in Backend Development
What it is
Backend frameworks like Express (Node.js), Django, and Flask (Python) provide the structure for building web servers and APIs. They handle routing, middleware, request parsing, and more so you do not start from scratch.
Why backend developers need it
Frameworks save time by solving common problems. Instead of writing your own HTTP parser and router, you use battle-tested tools that thousands of companies rely on.
What to learn
Express.js: routing, middleware, error handling
Django: ORM, admin panel, views, URL routing
Flask: lightweight setup, blueprints, extensions
Project structure and organisation
Configuration and environment management
Template engines vs. API-only backends
Choosing the right framework for your project
