Svelte 5 Runes Explained: Migrating from $: Reactive Statements to $state, $derived, and $effect
Svelte 5 replaces implicit $: reactive statements with explicit runes. Learn when to use $state, $derived, and $effect, with a worked migration and the mistakes that cause loops.
Designing Global State with Svelte Derived Stores: Requirements, Boundaries, and Checks
Learn how to use Svelte derived stores for global state: requirements, minimal design, data boundaries, operational checks, failure modes, and when to revisit the design.
svelteWhy SolidJS Skips the Virtual DOM for Direct DOM Updates
SolidJS replaces Virtual DOM diffing with fine-grained reactivity. Components run once; signals subscribe DOM nodes directly. This blog covers the run-once model, the destructuring trap, control-flow primitives, and async patterns with concrete verification steps.
Diagnosing Svelte UI Not Updating After State Changes
When a Svelte variable changes but the DOM stays static, the issue is usually missing assignment-based invalidation. Learn how to diagnose and fix it in Svelte 3/4 and note differences in Svelte 5.
Alpine.js List Rendering: Why Keyed Templates Matter for State Persistence
Alpine.js renders lists with x-for on <template> tags. Using a stable :key preserves DOM node identity—focus, transitions, input values—when arrays reorder. A worked example shows why index keys break and how to choose Alpine over a SPA for server-rendered pages with interactive pockets.
alpinejsSvelte Reactive Statements: Stop Manually Syncing Derived Values
Svelte's $: reactive statements turn derived state from an update-everywhere liability into a declare-once guarantee. Here's how they work, a working counter example, and the performance trade-off to watch.
