Course details
Learn how to use GitHub Copilot as an AI development partner, not just a code autocomplete tool. In this hands‑on course, you’ll build three real‑world applications: a React web app, a Python and Flask back-end service, and a React Native mobile app. Along the way, you’ll practice prompt engineering, use Copilot agent and CLI workflows, debug and refactor code, integrate external APIs, and generate documentation. You’ll also learn how to evaluate Copilot output and apply human judgment when guiding AI‑assisted development. By the end of the course, you’ll be prepared to collaborate effectively with Copilot across multiple platforms and apply these skills to your own projects.
Learning objectives
Use GitHub Copilot prompts and agent mode to plan, scaffold, and implement complete applications.
Build and modify web, back-end, and mobile applications using React, Python with Flask, and React Native.
Apply Copilot to debug errors, refactor code, and resolve configuration and dependency issues.
Integrate external APIs and AI services into applications using secure configuration practices.
Use Copilot to explain existing code, generate documentation, and improve code understanding and maintainability.
Evaluate when Copilot accelerates development and when human judgment is required to guide outcomes.
