Alert

A blocking, centered dialog that interrupts to confirm an action, surface a short message, or collect one small input.

import { Alert } from "@liquidify/react/alert"

Overview

Basic Alert

A focused starting point showing Alert with its essential configuration.

API

PropTypeDefaultDescription
actions
required
readonly AlertAction[]—The action buttons. Exactly two short actions lay out side by side; otherwise stacked.
childrenReactNode—Optional accessory content (e.g. a `<TextField>`) between the message and the actions.
classNamestring | undefined—Optional additional CSS class merged into the glass surface class. The supported per-instance customisation seam: override any `--lq-*` custom property from this class's CSS — the token cascade the engine reads (ADR-0004). No raw inline style is involved, so this stays ADR-0003 clean.
defaultOpenboolean | undefined—Uncontrolled seed for the open state (default `false`).
dismissibleboolean | undefined—Whether Escape / a scrim tap dismiss the alert (forwarded to Overlay). Defaults to `true`.
labelPropsLabelProps | undefined—Per-instance typography override for the title, forwarded to the internal {@link Text} (ADR-0028). Spread **last** over the computed default (`title3`/`bold`/`primary` with a message, else `body`/`secondary`), so an explicit consumer value wins.
material"frosted" | "regular" | "clear" | undefinedenclosing `<Material default>`, else `"regular"`Material of the glass surface — `frosted · regular · clear` (§06). Forwarded to the engine, which resolves the chain `prop ?? <Material default> ?? "regular"`, so a bare surface inherits the enclosing provider default.
messagestring | undefined—Optional secondary message; Modal wires it as the `aria-describedby` target.
messagePropsLabelProps | undefined—Per-instance typography override for the message, forwarded to the internal {@link Text} (ADR-0028). Spread **last** over the `body`/`secondary` default.
onOpenChange((open: boolean) => void) | undefined—Fires with the next open state on every close path (action, Escape, scrim).
openboolean | undefined—Controlled open state. Passing it switches Alert to controlled mode.
perf"low" | "high" | undefinedderived from `<Backdrop type>`, else `"low"`Perf budget of the glass surface (ADR-0006/0007). Forwarded to the engine as `data-glass-perf`; `"high"` opts this surface into the edge-lensing filter. When omitted, derives from the enclosing `<Backdrop type>` (§04).
refRef<HTMLDivElement> | undefined—Forwarded ref to the rendered element — the component's native root (or the merged child element on a component that opts into {@link SlottableProps}). Generic over `E` (charter `docs/api-conventions.md` §4 rule 1, default `HTMLElement`) so a component with a polymorphic root (Link's navigation / action mode union, Text's `as`) can instantiate the concrete element per variant instead of leaving every consumer with a widened `Ref<HTMLElement>`. A component that does not narrow simply inherits the `HTMLElement` default — source-compatible with every pre-existing non-generic `extends ControlProps`.
title
required
string—The dialog title — required, bold; Modal wires it as the `aria-labelledby` target.

Guidelines

Do
  • Use Alert when its semantics match the content or action.
  • Keep labels concise, specific, and consistent with the surrounding interface.
  • Test the component with keyboard navigation, zoom, and both color schemes.
Don't
  • Do not use Alert as a visual substitute for a different semantic element.
  • Do not rely on color or an icon alone to communicate essential meaning.
  • Do not override the component tokens with fixed values unless the product theme requires it.

Accessibility

Alert supports the documented keyboard interactions below.

Keyboard
  • Press Tab to move focus to the control.
  • Use the control's documented activation keys without trapping focus.
  • Provide an accessible name whenever the visible label is absent.
