<h2>Overview:</h2>
<p>The SvelteKit Flash Message library is designed to pass temporary data to the next request in a SvelteKit application. It is particularly useful for displaying success or failure messages after a POST request, which should be shown on the redirected page rather than on the form itself. This functionality is commonly referred to as a "flash message" and is often seen in PHP apps. The library aims to make implementing flash messages in SvelteKit easier, encouraging well-behaved web apps that redirect after POST requests.</p>
<h2>Features:</h2>
<ul>
<li>Passes temporary data to the next request</li>
<li>Displays success or failure messages after a POST request</li>
<li>Encourages redirects after POST requests</li>

<h2>Summary:</h2>
<p>The SvelteKit Flash Message library provides an easy way to implement flash messages in SvelteKit applications. It allows for the passing of temporary data to be displayed on the redirected page after a POST request. The library encourages well-behaved web apps that redirect after POST requests, making it easier to display success or failure messages to the user. The installation and usage guide provided in the documentation walks users through the necessary steps to integrate the library into their SvelteKit projects.</p>


<h2>Overview</h2>
<p>Superforms is a library that aims to make validation and displaying of forms in SvelteKit more user-friendly and efficient. It provides several features such as seamless merging of PageData and ActionData, server- and client-side data validation using Zod, auto-centering and auto-focusing on invalid form fields, and tainted form detection to prevent data loss. The library also offers support for nested data structures, multiple forms on the same page, and works both on the server and with single-page applications (SPA). Superforms can be easily customized and comes with a Super Debugging Svelte Component.</p>
