Svelte updates and a showcase by Eno on a new component called Svelte Cartesian. The episode starts with a changelog covering various fixes and improvements in Svelte, including event handler changes, input value handling, and CSS pruning. Eno then presents Svelte Cartesian, a tool for visual regression testing that helps render all combinations of a component's props for testing purposes.

Recent updates and features in Svelte and SvelteKit, with a focus on Storybook for Svelte Part 3: Testing

Brittney Postma of CodingCat.dev shows us how to create a store with Svelte and setting it to local storage so that it persists through refresh!

Custom stores can be used to wrap transforming data to and from storage mechanisms, either inside the browser or outside. Here we demonstrate a couple of fun transforms that have practical and real-world use.

Finite state machines provide an elegant, powerful approach for modeling complex behavior, and are ideally suited to many UI components. Alas, existing JavaScript FSM implementations feel verbose and bloated alongside Svelte's elegant, minimalist syntax. No more! svelte-fsm is the Svelte-esque FSM library. Discover the joy and benefits of using svelte-fsm to manage your components' state.

Maurice de Beyer on building reliable Svelte applications using Cypress and test-driven development.
