New TypeScript framework gains popularity: what you need to know

New TypeScript framework gains popularity

The TypeScript ecosystem continues to develop rapidly. In 2025, a new framework entered the arena, already being called the "Angular killer." We are talking about Qwik — an innovative tool for creating high-performance web applications that is gaining momentum among developers worldwide.

What is Qwik and why is everyone talking about it?

Qwik is a TypeScript framework focused on instant loading and maximum performance. Unlike traditional SPA frameworks (React, Vue, Angular), Qwik uses a unique lazy loading strategy at the individual component level. This means the browser loads exactly as much JavaScript as needed for the current user interaction.

Qwik's key feature is Resumability. Instead of classic hydration, where the application re-executes on the client, Qwik simply "resumes" execution from where the server left off. This provides a 2–3 times speed boost compared to Angular or React.

Key advantages of the new framework

• Instant startup — the application is ready to work in 100–200 ms even on slow devices.
• Zero JavaScript by default — code loads only when needed (clicks, scroll, input).
• Full TypeScript compatibility — strict typing, autocompletion, and safety at all levels.
• SEO optimization — server-side rendering (SSR) works "out of the box" without additional configuration.
• Easy integration — can be used with existing projects on React, Vue, or Angular.

Comparison with popular solutions

To understand why Qwik is gaining popularity, let's look at a comparison with other frameworks:

• Angular — powerful but heavy. Qwik is 5–10 times lighter in terms of transmitted code volume.
• React — flexible but requires manual optimization. Qwik optimizes everything automatically.
• Vue.js — simple and fast, but Qwik has higher performance on mobile devices.

According to the State of JS 2025 survey, Qwik is already used by 12% of professional TypeScript developers, and this figure is growing by 3% monthly. For comparison: Angular lost 2% of its audience over the same period.

Code example: creating a simple component

Here's what a minimal Qwik component with TypeScript looks like:

import { component$, useSignal } from '@builder.io/qwik';

export const Counter = component$(() => {  const count = useSignal(0);  return (    <button onClick$={() => count.value++}>      Counter: {count.value}    </button>  );});

Note: the $ at the end of names (onClick$, component$) is Qwik syntactic sugar that indicates lazy loading. The component code does not go into the main bundle but loads only when the user hovers over the button.

Who should pay attention to Qwik?

The new framework is especially relevant for:

• Creating landing pages and sites with high requirements
