Phoenix Views & HEEx Templates

About

This skill provides a comprehensive framework for building dynamic, secure, and maintainable HTML interfaces in Phoenix applications. It guides developers through the modern HEEx (HTML+EEx) ecosystem, focusing on the transition from traditional views to component-based architectures. By leveraging explicit attribute declarations, named slots, and advanced iteration patterns, the skill ensures that frontend code is both performant and consistent with Elixir best practices, covering everything from basic interpolation to complex LiveView integrations and component testing.

Key Features

• Declarative conditional rendering and optimized iteration shorthand
• Reusable function components using the attr macro for explicit attribute typing
• 72 GitHub stars
• HEEx template syntax with compile-time validation and automatic escaping
• Advanced slot patterns for flexible, nested UI composition
• Standardized patterns for LiveView integration and component-level testing

Use Cases

• Building a modular design system or component library within a Phoenix application
• Refactoring legacy Phoenix templates into reusable, testable function components
• Implementing complex layouts and dashboards using nested slots and dynamic assigns
