Learn how to fetch, cache, and handle loading and error states with SolidJS’s createResource. This guide walks through setting up a source signal, defining a fetcher, and using the resource in JSX, with checks and recovery strategies.
SolidJS replaces virtual‑DOM diffing with fine‑grained reactivity. Learn how signals and effects let you write efficient UI code, illustrated with a counter example and trade‑off discussion.
A diagnostic guide for SolidJS store reactivity failures. Learn why UI stays static after mutations, how to check proxy chains, and when to escalate SSR or renderer issues.
When building a SolidJS app you’ll often face a choice: use createSignal for simple atomic state or createStore for nested, relational data. This guide compares the two, explains trade‑offs, and shows a concrete example that validates reactivity isolation.
SolidJS’s signals, selectors, and memo primitives let you limit re‑renders to only affected components. Learn how to use them, check the reactive graph, and avoid common pitfalls with a hands‑on example.
An architecture note on SolidJS signals: the requirements they satisfy, the minimal setup, mutation boundaries, operational verification, and when to switch to a store.
SolidJS avoids Virtual DOM overhead by tracking dependencies at the signal level, updating only the exact DOM nodes that change. Learn how its once-per-component execution model works, see a live counter example, and understand the trade-offs around prop destructuring and library compatibility.
Learn how to manage SolidJS signals and use batching to prevent DOM thrashing and memory leaks in fine-grained reactive applications.
SolidJS compiles JSX to direct DOM updates wired to signals. Components run once, and only the specific DOM nodes that depend on a changed signal update, avoiding virtual DOM reconciliation.
