How to use a transition in Svelte! (Also Creating, updating, and deleting posts, and XSS protection)

Continuing to build out our SvelteKit application and blog, we now want and need the ability to create new posts, as well as update and delete our own posts only. In this episode, I show how to do all of that, as well as provide extra security against XSS by adding DOMPurify. We also explore using our first Svelte animation transition!
