Import

Import from the focused entry point below, or use the same named export from @tavojs/ui. Both are public APIs; measure the built application when comparing their bundle cost.

TSX

tsximport { CodeBlock } from "@tavojs/ui/code-block";

The component import loads compiled component CSS. Enable tavoUi() for your project theme variables, or import @tavojs/ui/theme.css once for the package default theme. The equivalent CSS-safe component alias is @tavojs/ui/css/code-block.

When to use

Use it when

Use `CodeBlock` for code examples

Choose something else when

Avoid CodeBlock when replacing interactive controls with content-only components.

Examples

These examples include imports and local state where interaction requires it. Render the exported component in a page after completing UI installation. Demo state stays in the mounted component; connect file handling, persistence, and data loading to your application as needed.

CodeBlock example

TSXCreate: src/components/examples/CodeBlockExample1.tsx

tsximport { CodeBlock } from "@tavojs/ui/code-block";

export function CodeBlockExample1() {
  return (
    <>
      <CodeBlock language="bash" code="npm install @tavojs/ui" />
    </>
  );
}

State ownership and DOM target

Concern	Contract
State	No component state contract is exposed; the application owns the rendered content and surrounding behavior.
DOM target	Public passthrough props target the component root. Treat nested elements and private class names as implementation details.

Anatomy and related components

This component exposes one public component root rather than a compound member API.

Limitations

Avoid CodeBlock when replacing interactive controls with content-only components.

Use only the documented props, entry points, and compound members. Internal DOM nesting and CSS class names can change without becoming part of the public component contract.

Accessibility

Content components should keep meaningful text and media alternatives available to assistive technology.

Provide alt text for meaningful images.
Use semantic text variants for headings and paragraphs.
Do not hide essential content visually unless VisuallyHidden is intentional.
