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!

Creating effective and unique data visualizations for news websites requires sophisticated tools. In fact, Svelte is currently becoming a gold standard tool to build interactive graphics for the world’s newsrooms. Why is that and what is so special about Svelte? Come and let’s go on a behind-the-scenes walk into the machine room of a modern interactive data visualization.

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.

Svelte is not just a JavaScript compiler. It is a way of thinking to design complex data visualizations. Come with me on a journey through one of my recent Svelte data visualization works.

In this episode we talk about stores! Custom ones, regular ones, cool ones! ALL THE STORES! We also rant a bit about the current state of build tools.
