Building Web Apps with Bolt

AI-assisted coding and cloud-based tools are already transforming how modern applications are built. Bolt.new, a powerful in-browser AI agent from StackBlitz, streamlines the development process, allowing you to prototype quickly, debug intelligently, and launch confidently--no local setup required. Whether you're new to full stack development or looking to supercharge your workflow, this accessible guide takes you from JavaScript and React fundamentals all the way to deploying sophisticated apps with Bolt.new and StackBlitz. Through real-world projects like a movie explorer and a Supabase-powered workout tracker, you'll master prompt-first development, tap into WebContainers for running backend logic in the browser, and discover a seamless path from idea to deployment. If you're ready to rethink how web apps are built--from the command line to the cloud--this book is your blueprint.
