Front-end Web Development Tutorials
Complete web applications combine Python backends with modern frontend technologies. Build user interfaces with HTML, CSS, and JavaScript that communicate with your Flask or Django APIs. Learn to integrate React, Vue, or vanilla JavaScript with Python web frameworks to deliver responsive, interactive experiences.

Rich user experiences come from handling forms, updating content dynamically with AJAX, and managing state in single-page applications. Serve static assets efficiently, implement authentication flows, and use templating engines or frontend frameworks. Master the connection between backend logic and frontend presentation to build full-stack Python applications.
Build a REST API with Flask or Django REST Framework that returns JSON. Configure CORS to allow requests from your React app. Use fetch() or axios in React to call your API endpoints. Deploy the backend and frontend separately or serve React as static files.
Frontend development builds the user interface with HTML, CSS, and JavaScript that runs in the browser. Backend development handles application logic, databases, and APIs with Python on the server. Full-stack developers work on both sides.
Use Django templates for server-rendered pages with simpler interactivity. Choose React, Vue, or Svelte for complex single-page applications with rich client-side state. Django templates are easier to start with, JavaScript frameworks offer more dynamic user experiences.
Configure Flask or Django to serve static files from a designated folder during development. In production, use a CDN, Nginx, or cloud storage like S3 to serve CSS, JavaScript, and images efficiently. Separate static serving from application logic.
AJAX lets JavaScript make asynchronous HTTP requests to update parts of a page without reloading. Use fetch() in JavaScript to call your Flask or Django endpoints. Return JSON from Python and update the DOM with the response.
