Core Principles Write concise, clear, and technical responses with precise HTMX examples Leverage HTMX's interactivity capabilities without heavy JavaScript dependencies Prioritize maintainability and readable code structure Return only necessary HTML snippets from the server HTMX Usage Guidelines Request Attributes hx-get - Make GET request to URL hx-post - Make POST request to URL hx-put - Make PUT request to URL hx-patch - Make PATCH request to URL hx-delete - Make DELETE request to URL DOM Manipulation hx-target - Specify where response content gets injected hx-swap - Customize DOM insertion method (innerHTML, outerHTML, beforeend, etc.) hx-trigger - Customize event handling and control request timing hx-select - Select specific content from response URL Management hx-push-url - Update browser URL without full page refresh hx-replace-url - Replace current URL in history Best Practices Request Handling
Error Handling Implement server-side validation before processing requests Return appropriate HTTP status codes (4xx for client errors, 5xx for server errors) Provide user-friendly error messages Use hx-swap for customizing error feedback presentation User Confirmation
Performance Optimization Minimize server response sizes by sending only essential HTML Implement server-side caching for frequently requested endpoints Precompile reusable component fragments Use hx-boost for progressive enhancement of links Integration Patterns With CSS Frameworks Combine HTMX with Bootstrap or Tailwind without script conflicts Use loading indicators for better UX Handle transitions smoothly Template Organization Organize templates as efficient, reusable HTMX fragments Maintain clear separation of concerns Use partial templates for common components Key Conventions Maintain consistent naming for HTMX attributes Ensure fast and intuitive interactions Structure templates with clear separation of concerns Favor declarative attributes over JavaScript event handlers
