This book gives you a complete introduction to full stack development with Java, Spring Boot, React, Flutter, and relational databases. It takes you through each layer of the stack with clear explanations and practical workflows. You learn how backend services process requests, apply rules, manage data, and support frontend applications. You also learn how frontend and mobile clients depend on consistent API behavior. Each chapter builds core skills that prepare you for real engineering tasks. The book uses simple examples, clean code, and structured steps to build confidence across the entire stack.
The backend chapters teach you how to design REST APIs. You work with controllers, request and response models, validation, error handling, and versioning. You learn how to apply clean layering with controllers, services, and repositories. You explore entities, database relations, query methods, pagination, sorting, and performance patterns. You also learn how to manage migrations, connection pooling, and data structure decisions.
The security section shows you how authentication, authorization, JWT sessions, passwords, and protected routes operate together. You learn predictable patterns that support safe backend applications. The testing section covers unit tests, integration tests, mocks, test data, and coverage targets, showing how to validate each layer of the backend.
The frontend chapters introduce React through components, state management, routing, forms, and API integration. You learn how React interacts with Spring Boot services and how to build simple, predictable interfaces. You also learn how session flows, error states, and joint deployment work. The deployment chapters explain Docker builds, CI and CD pipelines, monitoring, and logs. Each topic prepares you for production environments where stability and consistency matter.
You also get an appendix with reference commands, configuration samples, troubleshooting tips, templates, and a glossary. These references support fast learning and help you review concepts quickly.
