Question 1

How to create a web component with Atomico?

Accepted Answer

Use the `c` function to define a component with JSX, include a `` element as the root, and register it with customElements.define. For example, `const MyComponent = c(({ message }) =>

Hello {message}

, { props: { message: String } });`

Question 2

Atomico vs Stencil – which is better for web components?

Accepted Answer

Atomico is lighter and React-like, ideal for quick adoption by React devs. Stencil is compiler-based with more features and tooling, better for large design systems. Choose Atomico for simplicity; Stencil for richer ecosystems.

Question 3

Does Atomico work with Vue or Svelte?

Accepted Answer

Yes, Atomico components are standard web components, so they integrate natively with Vue, Svelte, or any framework supporting custom elements, without extra wrappers.

Question 4

What are Atomico's performance benchmarks?

Accepted Answer

The Atomico docs claim it's up to 60% faster than React in benchmarks, due to efficient virtual-dom updates. This makes it suitable for high-performance web apps.

Question 5

How to handle events in Atomico?

Accepted Answer

Define events in the component config using the `events` property, emit them with `this.dispatchEvent`, and listen in parents via standard DOM event handlers for clean communication.

Question 6

Is Atomico good for building UI libraries?

Accepted Answer

Yes, its cross-framework compatibility and type safety make it excellent for reusable UI libraries that need to work across different projects without framework lock-in.
