Vibe Coding FullStack with Spring Boot 4, React Using Junie (Udemy.com)

In 2025, AI coding agents like Junie are transforming software development. Imagine automating over 50% of your typical developer tasks and significantly accelerating your coding process! "Junie: AI-Powered Development for Java/Spring Professionals" is a comprehensive course designed to equip experienced Java/Spring Boot developers with the skills to harness Junie, JetBrains' powerful AI coding agent. Join John Thompson, founder of Spring Framework Guru, and discover how to leverage AI to boost productivity, improve code quality, and focus on innovative solutions in full stack application development.

Junie seamlessly integrates with JetBrains IDEs, making it ideal for those already using IntelliJ IDEA, PyCharm or WebStorm. This course will teach you how to use natural language prompts to instruct Junie, generate code, run tests, and manage complex projects.

You'll learn the concept of "Vibe Coding" and how to guide Junie to create production-ready software efficiently. Vibe Coding guided by experienced developers is a very powerful tool to achieve unimaginable gains in productivity and quality in full stack application development. This includes applying Vibe Coding to create a React based front-end application for your Spring Boot project, even if you're new to React. You'll learn to handle the iterative process of fixing errors with Junie, ensuring a clean build and passing tests for your React front end.

Your instructor was an early adopter of AI coding tools. Named a Junie Ambassador by JetBrains, John Thompson commits 50,000-80,000 lines of production grade code every week. In this course you will learn how to apply best practices to use AI Agents to produce high quality, production grade code.

While JetBrains Junie is used in the course. The techniques shown can be used with any of the agentic coding tools such as Claude Code, CodeX, Cursor, or even Grok Build.
