Master Claude Code

About this course

This comprehensive tutorial by Jeremy Morgan on freeCodeCamp guides developers through setting up and mastering Claude Code, Anthropic's powerful terminal-based AI assistant. The course walks you through the entire lifecycle of software development, beginning with the initial npm installation and local authentication, then moving directly into "vibe coding" a Python Flask weather web application from scratch. Beyond simple code completion, the video demonstrates Claude Code's advanced capabilities as an autonomous agent that can scaffold projects, configure virtual environments, write unit tests, update documentation, and manage Git commits. It also explores how to point the AI at complex, existing multi-file repositories to instantly map out architecture, diagnose race conditions from raw server logs, and refactor code. Finally, the tutorial emphasizes code quality, walking through structured prompting methods like the C.A.D.E. framework to have the AI thoroughly audit applications for architecture debt, SOLID compliance, error handling, and security readiness.
