Interactive server side components

Your app is paused on the server and resumes on the client where it left off. See how this eliminates hydration for truly instant web applications.

The web performance problem with modern frameworks

Most e-commerce websites struggle with poor Google PageSpeed scores because current frameworks prioritize runtime performance over time-to-interactive.

How replayable frameworks cause slow startup times

Traditional frameworks must download and execute the entire application's JavaScript on the client to "replay" the server's work and attach event listeners.

Qwik's resumable approach for instant interactivity

Qwik achieves near-instant interactivity by serializing application state and listeners into the HTML, allowing the client to "resume" execution with a tiny 1KB loader.

Comparing hydration models: monolithic, islands, and Qwik

A visual comparison shows how Qwik's fine-grained, out-of-order component hydration is more efficient than monolithic hydration or the island architecture popularized by Astro.

Live demo of a Qwik to-do application

A to-do app demonstrates how Qwik downloads only a tiny loader initially, then fetches small JavaScript chunks on demand as the user interacts with the UI.

How the Qwik optimizer automates code splitting

The Qwik optimizer automatically creates lazy-loading boundaries using `Q hook` markers, eliminating the need for developers to manually configure code splitting.

#7about 7 minutes

Serializing component relationships for fine-grained reactivity

Qwik serializes component state and relationships directly into the HTML, enabling the client to perform targeted updates without downloading or executing the entire application.

Q&A on performance, architecture, and PWA capabilities

Questions are answered regarding HTTP request overhead, using Qwik as a full framework replacement, managing HTML size, and leveraging resumability for PWA offline state.

Q&A on integration, debugging, and dependencies

The final questions address the process of integrating Qwik into existing projects, debugging via DOM attributes, and the framework's ability to handle circular dependencies.
