ABOUT THIS COURSE
Flask is a lightweight Python web framework used to build web applications, APIs, internal tools, and backend services. Its minimal design gives developers flexibility while supporting core web development patterns such as routing, templating, database integration, authentication, and secure form handling.
In this project-based course, you’ll build a database-backed Flask application from the ground up. You’ll begin with Flask’s structure, request lifecycle, routing, views, and Jinja templates. Next, you’ll connect the application to a relational database using Flask-SQLAlchemy, manage schema changes with migrations, and implement create, read, update, and delete functionality. You’ll then add forms with Flask-WTF, validate user input, protect against CSRF attacks, and implement secure authentication with password hashing and sessions.
By the end, you’ll be able to build practical Flask applications that connect interfaces, backend logic, databases, and security features.
