Qwik serializes component state into HTML for zero‑JS initial loads, but serializable logic and build‑tool configuration determine whether resumability holds up in practice.
A practical guide for Qwik developers on when to use useSignal versus useStore for local component state, compare their reactivity and serialization traits, see a concrete component example, and verify correct behavior.
Decide between Qwik's useStore and useSignal: compare reactivity, serialization, memory, and developer ergonomics. Follow the table, trade‑offs, and concrete example to pick the right state API for your component.
Qwik's resumability model makes the serialized server-to-client state graph a trust boundary. Learn how to design loaders and server functions that keep secrets server-side and pass operational checks.
Learn how Qwik's $ syntax enables resumability and fine-grained lazy loading to eliminate the hydration bottleneck and reduce initial JavaScript payloads.
Qwik skips hydration by serializing listeners and state into HTML attributes, loading JavaScript chunks only when the user interacts. A concrete counter example shows how to verify lazy loading in DevTools.
Qwik’s resumability and QRL lazy loading let you build instant‑loading web apps. This blog walks through how QRLs defer code until interaction, shows a concrete Qwik City example, discusses trade‑offs, and gives actionable steps to adopt the pattern.
A concise guide to designing a Qwik app that leverages resumability: requirements, minimal component structure, trust boundaries, verification steps, failure modes, and when to revisit the design.
Qwik's $ suffix is the entire lazy-loading mechanism in one character. Here's what the optimizer does with it, how to verify it works, and the footgun of forgetting it.
