QR Code

A React component in Beamline's Content & display category.

A scannable code set as gradient dots with rounded finder rings and an optional centre mark; a new value ripples out from the centre.

Use it for

• A deposit address or wallet a person scans with a phone.
• Pairing a device or signing in on mobile from a desktop screen.
• A share or invite link meant to be opened on another device.

Not for

• Decoration: a code nobody is meant to scan.
• Long payloads (> ~300 characters): the dots get too small to scan; link to them instead.

Anatomy

• plate
• dots (data modules)
• finder rings (three corners)
• centre mark (optional)

Variants

• tone: auto, light

States

• static
• value changed (ripple)
• with centre mark (high error correction)

Keyboard

• Not focusable; pair it with a copy button for the value.

Motion

On a value change each dot grows from 20% to full size with no overshoot (--pui-duration-spring on --pui-ease-out-strong), delayed by its distance from the centre (--pui-stagger-char per module, a cascade of about 0.25 s), so the new code spreads outward. Never on first paint. Reduced motion: the new code appears at once.

More in Content & display

• Advertisement: A sponsor or promo slot that turns through its ads on a hairline that fills; hovering or focusing holds the current ad.
• Avatar: A person or account in a small space: a photo, or initials on the hue their name always gets; presence dot; circle for people, square for companies.
• Avatar group: A team in a small space: overlapping faces that name themselves on hover or focus, and “+N” naming the rest.
• Badge: A short status, category or count label: six tones, an icon or a status dot, two sizes.
• Code block: Code to read and copy: highlighted in the system's colours, numbered, marked lines, long files folded behind “Show all”.
• Comment thread: A discussion attached to something: replies, reactions, @mentions, editing and deleting your own, resolve that folds the thread.
• File diff: A change to one file as a unified diff: line numbers, tinted lines, only the changed words marked, long unchanged stretches folded; give rows or just…
• Image compare: Two images in one frame with a divider: drag anywhere, or arrow keys on the handle; horizontal or vertical, with captions.
• Item: The generic list row: media, title, description, meta and trailing actions; becomes a link or button when interactive.
• Kbd: Keyboard keys as keycaps; `mod` resolves to ⌘ or Ctrl per platform, symbols are spoken as words.
• Lightbox: A full-screen image viewer: a thumbnail grows into it and shrinks back, arrows and ←/→ step through the set, Esc or a downward drag closes it.
• Logo Carousel: A wall of logos shown a few at a time: every few seconds the slots turn left to right, each logo leaving upward as the next rises in.
• Marker: A labelled point in a stream: a status event with an icon between messages, or a label such as "Today" between two hairlines.
• Slot text: Text and numbers that roll into their new value on reels, digit by digit from the right; other characters fade. Read as plain text by assistive tech.
• Text morph: A short label that becomes its next state letter by letter: shared letters glide into place, new ones arrive, old ones leave.
• Text reveal: A headline whose words rise into place once, the first time it scrolls into view; never repeats.
• Text shimmer: Ongoing work said in words (“Thinking…”) with a calm band of light passing across them; stops when inactive.
• Timeline: What happened, newest first and grouped by day: people with avatars, systems with toned icons, relative times with the exact time on hover, details in…
• Video player: A video player on the native <video> element: title bar with an external link and close, centre play with ±10 s, scrub, time, volume, speed, captions…
