SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Named, meaningful failure states in your domain help callers understand exactly what went wrong and why, instead of surfacing generic exceptions.

Core Features & Use Cases

  • Domain-specific exceptions communicate precise failure reasons to callers.
  • Enforce consistent naming, static constructors, and context data across the codebase.
  • Use in Laravel or PHP applications to map to tailored HTTP responses and logging.

Quick Start

Create a domain-specific exception class for each error, implement a named static constructor for readable throw sites, and wire a renderer to map exceptions to HTTP responses.

FAQPage Schema
How do I create domain-specific exceptions in Laravel instead of using generic error wrappers?

Domain-specific exceptions communicate precise failure reasons like not found, invalid state, or business rule violations to callers. They replace generic error wrappers by carrying domain-specific data and using named static constructors for readable throw sites.

How do I map custom PHP exceptions to HTTP responses in a centralized location?

You map custom PHP exceptions to HTTP responses by wiring a centralized renderer into your application. This renderer intercepts domain-specific exceptions and translates their failure reasons and context data into tailored HTTP responses.

What is the best way to structure exception classes for business rule violations in PHP?

The best way to structure exception classes for business rule violations is to create a dedicated domain-specific exception for each error. Use named static constructors for readable throw sites and ensure each exception carries relevant domain-specific data.

When do I need dedicated exception classes for invalid state errors?

You need dedicated exception classes for invalid state errors when you want to communicate precise failure reasons to callers. Using domain-specific exceptions instead of generic wrappers ensures callers understand exactly what went wrong and why.

Can I use static constructors to improve exception readability in my PHP domain logic?

Yes, you can use static constructors to improve exception readability in PHP domain logic. Named static constructors create readable throw sites and enforce consistent naming and context data across your codebase.

Does this approach to error handling work outside of Laravel in standard PHP applications?

Yes, this error handling approach works in standard PHP applications. The core concepts of using domain-specific exceptions, static constructors, and centralized rendering can be applied to any PHP codebase to communicate precise failure reasons.
