18 - State Management: Complex State Objects, Derived Rune, Universal Reactivity (.server.ts pages)

Description

In Part 18 of our SvelteKit course, we are moving beyond the basics and diving into State Management in Svelte 5. The old "store" pattern is a thing of the past. Svelte 5 introduces Runes, a unified reactivity system that makes managing data cleaner, faster, and more intuitive. We build a Team Task Manager from scratch to demonstrate how to handle complex data structures without the headache of immutable spreads. You'll learn how to keep your UI in perfect sync using $derived and how to architect professional-scale apps using Universal Reactivity in .svelte.ts files. ------------------------------------------------------------------------------------- 🚀 What you will learn: • Complex State: Managing arrays of objects with deep reactivity using $state. • Derived Logic: Using the $derived rune to calculate totals and progress automatically. • Universal Reactivity: Moving logic out of components and into TypeScript classes using .svelte.ts. • Fine-grained Updates: Understanding how Svelte 5 updates the DOM surgically for maximum performance. • State Organization: Best practices for local vs. global state and the "Rule of Proximity." ------------------------------------------------------------------------------------- Chapter: - 00:00 Intro 00:35 Complex State Objects 02:48 Derived State 04:15 Universal Reactivity 06:32 Fine-Grained Reactivity 07:26 State Organization ------------------------------------------------------------------------------------- Support Me: - Patreon: https://www.patreon.com/c/CodeHubOfficial ------------------------------------------------------------------------------------- Related Videos: 1.
