Toast

Status: stableAccessibility reviewedtenet-ui@0.4.0

Import

import { Toast, useToast } from 'tenet-ui';

Source: src/components/Toast/Toast.tsx

Usage guidelines

When to use: brief, transient, non-blocking feedback about something that just happened (“Saved”, “Copied”, “Upload failed”). For a message anchored to content use Banner; for something that must be acknowledged use Dialog.

Setup

• Wrap your app once in <ToastProvider> (optionally set duration and placement). Call const { toast } = useToast() anywhere beneath it.

Rules

• Keep it short — a title plus one line of message. Toasts are glanceable, not a place for forms or long text.
• Pick variant by meaning; danger is announced assertively (role="alert"), the rest politely (role="status"). The viewport is a labelled live region.
• Let them auto-dismiss (default 5s); only set duration: 0 for a message the user must dismiss, and always keep the manual dismiss button.
• Never put critical, must-act information only in a toast — it disappears. Mirror it in a Banner or inline error.
• Don’t stack many at once; collapse repeats rather than flooding the corner.

Do / Don’t

• ✅ toast({ variant: 'success', title: 'Saved', message: 'Your changes are live.' })
• ✅ <ToastProvider placement="bottom-right"><App /></ToastProvider>
• ❌ A toast as the only record of a validation error the user must fix.
• ❌ Long, interactive content inside a toast — use a Dialog.

See also: Banner for persistent or anchored messages, Dialog for decisions, FormControl.Validation for field errors; system guideline feedback has the decision table.
