description Qwik Overview

Qwik is a new JavaScript framework focused on delivering incredibly fast initial page load times through its unique 'resumability' and 'progressive hydration' techniques. Unlike traditional SSR or SSG, Qwik allows the browser to resume execution of JavaScript code on the server, significantly reducing the amount of JavaScript that needs to be downloaded and parsed. This results in a dramatically improved user experience, especially on slower devices and networks.

help Qwik FAQ

What is Qwik's main idea?

Qwik is a JavaScript framework built around resumability, which lets the browser continue work serialized by the server instead of rerunning a large application startup. Its goal is to reduce the amount of JavaScript needed during the first page load.

Who created Qwik?

Qwik was created by Miško Hevery, the engineer known for creating AngularJS. It is associated with Builder.io, which maintains the framework and its surrounding tools.

How is resumability different from hydration?

Traditional hydration sends server-rendered HTML and then runs JavaScript in the browser to attach behavior to the page. Qwik stores enough serialized state in the HTML so that only the needed event handler or code chunk is loaded when the user interacts.

Can Qwik be used with React components?

Qwik has its own component model and syntax, while Qwik City provides routing and application features. Builder.io also provides integrations such as Partytown and other tooling, but a React application is not automatically a Qwik application without adaptation.
