Button

A Base UI (Angular) button is a Tailwind-styled directive you copy in with npx base-ui-cli add button. Put base-button on a native button, then set color and size. There is no runtime package — the source lives in your repo, so you can restyle it or swap in base-progress-button for a loading state.

When to use

Primary and secondary actions on forms, dialogs, and toolbars.
When you want a native button element with Base UI (Angular) colors and sizes, not a custom element.
Loading submits — pair with base-progress-button so the width stays stable.

When not to use

Navigation that should be a link — use base-link or routerLink on an anchor.
A row of related toggles — use button-group or a checkbox/toggle instead.

Install with npx base-ui-cli add button.

Keyboard & accessibility

Role: Native button. Disabled controls are not in the tab order.
Focus: Focus follows DOM order. Loading uses aria-busy on base-progress-button and blocks activation.

Shortcuts

TabMove focus to the next control
EnterActivate the focused button
SpaceActivate the focused button

Site-wide VPAT-style notes live on the accessibility report.

Installation

Run the following command to add this component to your project:

bash
