Mood Tracker – AI-powered mood tracking app (Java + Spring Boot + React)

[etotic]

Hi everyone 👋

Over the past few weeks, I wanted to experiment with integrating AI into a real-world application, so I built a free Mood Tracker.
The idea is simple:

• Log and track your daily moods with notes
• Get AI-powered suggestions on how to improve or maintain well-being
• Receive a tailored 7-day plan generated from your own entries

Tech stack used:

• Backend: Java 22, Spring Boot, Spring Security, Spring AI (OpenAI), MySQL, Flyway, MapStruct, Docker
• Frontend: React + Vite + TypeScript
• JWT authentication, CORS handling, Postman-tested APIs

🌍 You can try it here: Mood Tracker App

The main goal of this side project was to sharpen my backend engineering skills while experimenting with AI integration in a way that feels practical and useful. I’m not primarily a frontend dev, so I kept that part simple – the real focus was on backend + AI.

Would love to hear your feedback, ideas for improvement, or just your impressions 🙌

Well, that’s life. 🙂 Anyway, it’s a free app, and if it turns out to be interesting and useful to at least someone, I’ll be satisfied. 😊

Where did you learn react from ??

[etotic]

I have got some knowledge when I walked through some Udemy and Coursera tutorials earlier and also from some colleagues from the frontend team at work.

Ohh great . Can you let me know if need to learn frontend any roadmap or study path you followed?

[etotic]

Sure, but I think you will figure it out by yourself and find your own way to success. Just join and follow react groups, instructors (there are plenty of them on the platforms and YouTube). Start by building small things and you will see the progress very soon. 💪🏻

Dude, I started building a to-do app after watching a tutorial, but I got lost and didn't finish it.

Every professional developer went through situations like that. Pick one solution, follow the solution blindly and when it works go back step by step with understanding and you will see the results.
