Molten Hold, animated React component
Hold to confirm by pouring molten metal. Press and hold and metal pours into the channel: the front is a glowing meniscus, white-orange at the lip, that shivers as it runs and throws heat onto the groove ahead, while behind it the metal cools through orange and red into chrome, its skin breaking into slow cells. Let go early and it drains back. Hold to the end and the glow fades, one ripple runs the length of the set bar, and the label is pressed into the metal. Space or Enter hold it from the keyboard. Until you touch it, it holds and lets go by itself.

A low thump and a short whoosh as the metal starts to run, then a sizzle that follows the front: grains of hiss and crackle that come closer together and brighter as the channel fills, with the odd spit and a low glug. Let go early and it drains with an airy slide and a few bubbly notes stepping down. Hold to the end and it sets with a heavy thunk, a hiss of steam as the metal quenches, a ring of chrome and a sheen that runs the length of the bar. Pressing it again plays a soft reverse blip. Sound is off on this site until you switch it on.

Move the controls and watch it change. Copy code gives you a snippet with only the props you changed.
Press and hold
Props
| Prop | Type | Default | What it does |
|---|---|---|---|
| autoplay | boolean | false | Holds and lets go by itself until the first touch. Held still under reduced motion. |
| volume | number | 0.8 | Loudness of the sounds, 0 to 1. |
| label | string | Hold to publish | The words on the bar before it is held. |
| doneLabel | string | Published | The words pressed into the metal once the hold is complete. |
| duration | number | 1.8 | Seconds of holding it takes to fill the channel. |
| onConfirm | () => void | — | Called once, when the channel is full. |
| enableSound | boolean | true | Plays interface sounds on interaction. They follow the sound switch (setSoundsEnabled, on by default) and stay silent on hover. Autoplay makes the same sounds once the visitor has used the page. Pass false to silence this component. |

Set up your project once
You need a Next.js project with Tailwind CSS and the
@/import alias. In its root folder, run this once. It createscomponents.jsonand thecn()helper insrc/lib/utils.ts:npx shadcn@latest init -d
Starting from nothing? The Quick Start walks through the whole thing.

Connect the registry with your API key
Molten Hold is a Pro item, so the CLI has to send your API key. Do this once per project:
- Create a key at nexus-ui.com/dashboard/api-key. Copy it straight away: it starts with
nxs_and is shown only once. - In your project root, next to
package.json, create a file named.env.localwith this line, using your own key:NEXUS_API_KEY=nxs_your_key_here
- Open
components.jsonand add this entry inside the outermost braces, next to"aliases". Leave{name}and${NEXUS_API_KEY}exactly as written; the CLI fills them in:"registries": { "@nexus-labs": { "url": "https://www.nexus-ui.com/api/registry/{name}", "headers": { "Authorization": "Bearer ${NEXUS_API_KEY}" } } }
- Create a key at nexus-ui.com/dashboard/api-key. Copy it straight away: it starts with
Molten Hold questions
Does it make sound, and how do I turn it off?
A low thump and a short whoosh as the metal starts to run, then a sizzle that follows the front: grains of hiss and crackle that come closer together and brighter as the channel fills, with the odd spit and a low glug. Let go early and it drains with an airy slide and a few bubbly notes stepping down. Hold to the end and it sets with a heavy thunk, a hiss of steam as the metal quenches, a ring of chrome and a sheen that runs the length of the bar. Pressing it again plays a soft reverse blip. Sounds are synthesised with the Web Audio API, so there are no audio files, and they only play after a click or key press. Pass `enableSound={false}` to silence this component, or call `setSoundsEnabled(false)` from `@/lib/ui-sounds` to switch every sound off at once. The CLI installs `@/lib/ui-sounds` with the component.
