Architecture of Complex Web Applications. With Examples on Laravel

The book is dedicated to the practical aspects of designing the architecture of complex web applications with examples in Laravel. It addresses typical problems that arise when scaling projects and approaches to solving them, including structuring application layers, organizing business logic, separating concerns, and working with infrastructure code. Common architectural mistakes related to excessive dependency on frameworks are analyzed, and alternative solutions based on proven practices are proposed. Error handling and validation, implementing a domain layer, using architectural patterns like CQRS and Event Sourcing are described. Special attention is given to unit testing, dependency management, event-driven approaches, and the implementation of patterns resilient to increasing complexity.
