Introduction
Qwik, created by Miško Hevery (creator of Angular), proposes a radically different model: resumability. Instead of hydrating the entire app on load, it only executes the necessary code.
What is resumability
Traditional hydration runs the entire application on the client to recover state. Resumability pauses execution on the server and resumes it on the client without repeating work.
How Qwik works
Qwik serializes application state into the HTML. When the user interacts, only the specific component's code is downloaded and executed, not the entire app.
Extreme lazy loading
Every event handler, every effect, every listener loads on demand. This results in initial bundles under 1KB in many cases.
Real Performance
Qwik applications consistently score 100 on Lighthouse, even on complex sites with heavy interactivity.
Conclusion
Qwik represents the future of the web with zero unnecessary JavaScript. At Vynta, we evaluate Qwik for projects where performance is critical.
