# From Node.js to Spring Boot: A Full-Stack Developer's Journey
## 🚀 About This Repository
This repository documents my journey of learning Java and the Spring Boot framework, guided by the mentorship of a senior developer. As a full-stack developer with 3+ years of experience in the Node.js ecosystem (React, NestJS, Express), my goal is to add a powerful, enterprise-grade toolset to my backend arsenal.
This is a living document and a collection of all the projects and code written during this learning process. It follows a structured, project-based roadmap, culminating in a full-stack virtual credit card application.
* **The Mentee:** A Full-Stack Developer proficient in JavaScript/TypeScript.
* **The Mentor:** A Senior Full-Stack Developer with 10+ years of experience, including 7+ years with Spring Boot.

## 🗺️ The Roadmap
This roadmap is divided into distinct phases, each with clear objectives and practical projects.
### Phase 0: The Foundation - Core Java (Weeks 1-2)
* [ ] **Week 1:** Java Syntax & OOP Fundamentals
* [ ] **Week 2:** Essential APIs (Collections, Streams, Lambdas) & Tooling (Maven)
* **Project:** `bank-account-cli` (A simple command-line banking application).
### Phase 1: Entering the Spring Ecosystem (Weeks 3-4)
* [ ] **Week 3:** Inversion of Control (IoC) & Dependency Injection (DI)
* [ ] **Week 4:** Understanding Spring MVC
* **Project 1:** `di-message-service` (A non-web app demonstrating pure Spring DI).
* **Project 2:** `manual-spring-mvc` (A minimal web app to appreciate Spring Boot's magic).
### Phase 2: Spring Boot - Rapid Application Development (Weeks 5-8)
* [ ] **Weeks 5-6:** Building a REST API with Spring Boot & Spring Data JPA (with H2)
* [ ] **Weeks 7-8:** Securing the API with Spring Security (JWT) & Connecting to PostgreSQL
* **Project:** `todo-api` (A full CRUD REST API for a To-Do list application with user authentication).
### Phase 3: Polishing the Arsenal - Advanced Concepts (Weeks 9-11)
* [ ] **Week 9:** Advanced JPA (Relationships) & Transactions (`@Transactional`)
* [ ] **Week 10:** Unit & Integration Testing (JUnit 5, Mockito, MockMvc)
* [ ] **Week 11:** Production Topics (Profiles, DTO Mapping, Caching, Dockerizing)
* **Project:** Evolve and refactor the `todo-api` with advanced features and tests.
### Phase 4: The Capstone - Full-Stack Application (Weeks 12-16)
* [ ] **Weeks 12-14:** Backend Development for the Credit Card App
* [ ] **Weeks 15-16:** Frontend (React Native) & Full-Stack Integration
* **Project:** `virtual-credit-card-app` (A complete full-stack application simulating a virtual credit card service).

## 🏃 Getting Started
### Prerequisites
* **Java JDK 17** (or newer, we will use 17 as it's the latest LTS version)
* **Apache Maven**
* **PostgreSQL** Database Server
* An IDE like **IntelliJ IDEA Community Edition** (highly recommended)
### Running a Project
Each backend project is a standard Maven project. To run any of them:
1. Navigate to the specific project's root directory:
```bash
cd /
# Example: cd 02-spring-boot-basics/todo-api
```
2. Run the application using the Spring Boot Maven plugin:
```bash
mvn spring-boot:run
```
3. The application will start on the configured port (usually `8080`).
> **Note:** Each project folder may contain its own `README.md` with more specific instructions for setup and API endpoints.
