Overview

The Alert Banner component is a UI component in Lerpa UI's 1318-item shadcn-compatible registry, built for React 19 and Tailwind CSS v4. It exposes 7 configurable props, documented in the table below. It needs no dependencies beyond Lerpa UI's standard peer set (React, Tailwind, and Framer Motion). Install it once with the CLI and the source is written into your project as a file you own — read it, edit it, or remove it, with no version to lock.

Install options

Add Alert Banner with the Lerpa CLI, or with the shadcn CLI pointed at the registry URL — the source is shadcn-compatible, so either tool writes the same file.

# Lerpa CLI
pnpm dlx lerpa-cli add alert-banner

# shadcn-compatible
npx shadcn add https://lerpaui.com/r/alert-banner.json
