Author argues deep API knowledge still matters in an age of AI code generation

A Laravel developer has published a book on building REST APIs, arguing that AI tools like Claude and Copilot can generate working code in minutes but cannot make the architectural decisions that determine whether an API holds up in production. The author contends that developers who rely solely on AI-generated output without understanding it risk becoming redundant, since their only contribution becomes a prompt anyone could write. The book follows a single API project called BookShelf from a clean Laravel install through to a VPS deployment, covering design, validation, authentication, and authorization as interconnected decisions rather than isolated steps. It also addresses performance concerns such as N+1 queries and security topics including rate limiting and CORS, areas the author says AI handles poorly. Every code decision in the book is explained in context, with the full source available on GitHub tagged chapter by chapter.
