Series: Building a Social Network with Flask & Stream – Part 12

The tutorial provides a step-by-step guide to building a full-stack application using Flask, React/Redux, and Stream, focusing on setting up the foundational structure with Server Side Rendering (SSR). It begins by outlining the advantages of SSR, such as combining server and client code into one repository, avoiding CORS issues, and utilizing familiar packages like flask-login for authentication. The article walks through initializing a project with a virtual environment, installing essential Flask packages, and creating top-level Python files for backend functionality. It details setting up configurations, directories, and models, while also explaining the integration of React components via Webpack and Babel for frontend development. The tutorial concludes with instructions on testing the setup by running the application locally, providing a solid base for further development of user authentication and profiles in subsequent tutorials.
