About the Book
Todo desenvolvedor já herdou um projeto onde mexer em qualquer coisa quebra
outra. As causas se repetem: débito técnico que ninguém decidiu contrair,
organização em torno do framework do momento, arquitetura copiada de um
repositório famoso sem o contexto que a justificava. Na raiz, uma só doença,
complexidade que não paga o aluguel que cobra.
FOCUS parte de uma tese simples: arquitetura existe para reduzir complexidade e
decisões, e qualquer outra justificativa é secundária. O nome é o método:
Feature-Oriented, Clean, Unidirectional, Scalable (orientado a feature, limpo,
unidirecional, escalável). Não é framework nem boilerplate, e não nega as
arquiteturas que vieram antes: é uma curadoria opinativa delas, que na dúvida
entre mostrar opções e dar direção, dá direção.
Cada conceito nasce de um problema concreto e se prova num sistema real, um
e-commerce full-stack construído ao longo do livro, com catálogo, carrinho,
pedidos, estoque e pagamento. O código essencial aparece impresso e o entorno
vive num repositório companion, com o mesmo desenho aplicado em treze ecossistemas
de front e back, de Flutter e React a ASP.NET, Spring e FastAPI. Código que muda
junto mora junto, e a árvore de pastas conta o que o sistema faz.
