Udemy – Live Vibe Coding Full‑Stack: Build a fitness app, Test & Fix

This course takes learners on a practical journey of building a full‑stack fitness tracker application from the ground up. Starting with the frontend, students design an interactive calendar and form that allow users to log workouts, minutes, and notes. They then connect this interface to a backend API, handling requests and responses, and finally link everything to a database so entries persist across sessions. By following this flow, learners experience the complete cycle of modern web development.

Throughout the course, we emphasize Copilot‑style vibe coding — an iterative, collaborative approach where problems are broken into small steps, tested quickly, and refined with confidence. Learners see how progress builds piece by piece, making coding feel approachable and rewarding. Alongside feature development, we introduce regression testing, teaching students to re‑run core functionality after each change to ensure stability. This habit helps prevent accidental breakages and builds professional discipline.

We also tackle classical bugs that every developer encounters, such as off‑by‑one date errors, missing DOM elements, and backend mismatches. Debugging these issues gives learners real‑world problem‑solving experience. By the end, participants will not only have a working fitness tracker but also the confidence to build and maintain frontend, backend, and database systems with clarity, stability, and resilience.
