What are Action Fallbacks in this context?

Action Fallbacks allow you to centralize error handling by delegating non-standard response tuples (like error tags) to a dedicated fallback controller, reducing boilerplate.

Can it assist with controller unit testing?

Yes, it includes best practices and code snippets for using ConnCase to test HTML responses, redirects, and flash messages effectively.

Does it support both HTML and JSON API responses?

Absolutely. The skill covers configuring supported formats and rendering responses for both traditional web views and modern JSON-based APIs.

How does this skill improve Elixir development?

It provides specialized patterns and guidance for writing clean, efficient Phoenix controllers, ensuring you follow framework conventions like 'thin controllers' and verified routes.

Does this skill support Phoenix verified routes?

Yes, the skill explicitly encourages the use of the ~p sigil for all internal redirects and path generation to ensure compile-time route safety.

API Development

Streamlines the development and testing of Elixir Phoenix controllers by implementing best practices for request handling and response orchestration.

About

The Phoenix Controllers skill empowers Claude to act as an expert Elixir developer, providing structured guidance for building robust web controllers within the Phoenix framework. It establishes standardized patterns for extracting request parameters via pattern matching, managing connection states, rendering templates, and handling redirects with flash messages. By enforcing the 'thin controller' principle and utilizing action fallbacks, this skill ensures that backend logic remains maintainable, secure, and properly integrated with Phoenix contexts and verified routes.
