Build svelte components with test first aproach by using Jest and the Svelte Testing Library. We will see how we can query elements, how we can interact with them and also how we can replace external service without mocking.

Join us for the last few Svelte Summit videos where you'll learn about i18n and preprocessors!

A Svelte and SvelteKit changelog update covering CSS parsing improvements and request handling fixes. A community showcase of "Sals," a functional reactive alternative to Svelte stores with better async and error handling. A guide to configuring Vitest for browser-like environments to properly test Svelte components' `onMount` lifecycle hook.

A weekly Svelte update from February 2024 covering changelog highlights, community showcase featuring Paraglide JS for internationalization, and discussions about Svelte 5 progress.

A Svelte 5 changelog overview covering snippets, bug fixes, and migration guidance. Live coding of runes-based dynamic filtering plus exploration of effect, onMount, and reactivity features.

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.

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.
