Strategies for Leveraging Laravel Form Request Validation with HTMX for Dynamic Partial Updates

[tvarwig]

Aloha,

I am currently integrating HTMX with Laravel Blade views in my project and have encountered a challenge regarding the utilization of Laravel's Form Request Validation feature. According to the docs, should validation fail, the framework is designed to automatically generate a redirect response, directing the user back to their previous location. This behavior, while useful in traditional form submissions, poses a limitation when working with HTMX, as my objective is to return a view containing the validation errors directly, rather than performing a full-page redirect.

The essence of this challenge lies in the nature of HTMX interactions, which are designed to enhance user experience by updating specific parts of the page (i.e., the innerHTML of an element) without necessitating a complete page reload. The redirection feature, therefore, contradicts this approach by reloading the entire HTML content, thereby unnecessarily increasing both compute and bandwidth usage.

To circumvent this limitation, it appears the most viable solution is to forego the use of Laravel's custom Form Request Validation in favor of manual validation using the Validator class. My approach would involve checking for validation failures via $validator->fails() and, upon failure, returning a view of the specific component intended for update. While this way offers a workaround, it also introduces additional complexity and deviates from Laravel's validation best practices.

I am needing to know whether there is a more accepted solution or best practice for the use of Laravel and HTMX I am interested in any strategies that might allow for the seamless integration of Laravel's validation features with the dynamic, partial page updates facilitated by HTMX, without resorting to the less desirable full-page reloads.

One solution I thought of is to create a function int he Form Validation Request to override errors in lieu of redirecting.
