How do you connect a Django backend to a React blog frontend?

Configure Django API endpoints and CORS, then call the backend from React using its deployed or local API URL.

Why use FormData when creating a blog post with an image in Django and React?

FormData sends text fields and image files together as multipart form data, allowing Django to receive the uploaded image.

How do protected routes work with JWT authentication in a React blog app?

A Protected Route checks for a valid JWT before rendering a page and redirects unauthenticated users to the login page.

Set up a full-stack Django + React project and understand the initial architecture
Create the React app with Vite before integrating Tailwind CSS and shadcn/ui
Build core UI components incl. responsive navbar with hamburger toggle state
Implement pages and routing with React Router and use Outlet for nested layouts
Add dark/light themes and persist the choice via localStorage across refreshes
Connect Django REST API to React, handling CORS and environment-based API URLs

Add paginated blog listing; request pages using a ?page= query parameter
Render blog detail data and conditionally show edit/delete only for the owner
Implement user registration and JWT auth; Protected Routes block unauth users
Securely fetch/display logged-in username by calling a protected 'current user' endpoint
Create/update posts with images using FormData for multipart/form-data uploads
Delete blogs by passing the blog ID/slug to the delete request function

About the free online course

Create a modern blog application end to end and learn how full-stack development works in a real workflow. This course guides you through building a production-style web app using Django for the backend and React for the frontend, focusing on the skills employers expect: clean project structure, reusable components, reliable data fetching, secure authentication, and a UI that feels polished on desktop and mobile.

You will start by setting up both sides of the project and building core interface pieces like navigation and page layouts, then progress into client-side routing for a true multi-page experience. As you enhance the user experience, you will add light and dark themes that persist across refreshes, helping you understand state, storage, and practical UI patterns that users actually notice.

On the backend-to-frontend connection, you will learn how to move from a disconnected interface to a fully integrated application: consuming Django endpoints from React, handling asynchronous requests, and managing server state with React Query. Pagination and detail pages are implemented in a way that mirrors real content sites, so you get experience building features that scale beyond a handful of posts.

User accounts are a central part of the project. You will implement registration and JWT-based authentication, then protect routes so only authorized users can access sensitive screens. You will also handle login/logout flows properly and display user-specific data securely. From there, you will build CRUD features for blog posts, including image uploads using FormData, editing via modals, and permission-aware controls so edit and delete options appear only when appropriate.

To round out the experience, you will create dynamic profile pages tied to each user through routing, add profile updates, and finish with deployment. You will learn the practical tweaks needed after going live so the frontend can successfully fetch data from the backend, preparing you to ship full-stack apps with confidence.
