Code

How Upload progress button is used: the demo's code. The component's own source comes with a free account.

"use client";
import * as React from "react";
import Component, { type Props, type State } from "@/components/ui/upload-progress-button";
const settings = {"title": "Choose a file", "showContext": true};
const ease=(x:number)=>{x=Math.max(0,Math.min(1,x));return x*x*(3-2*x)};
const pulse=(t:number,a:number,b:number)=>ease((t-a)/.3)*(1-ease((t-b)/.3));
export function showcase(time:number):State{const t=((time%6)+6)%6;return t<.8?{active:0,reveal:0}:t<3.2?{active:1,reveal:ease((t-.8)/2.4),selected:'Design-notes.pdf'}:t<5?{active:2,reveal:1,selected:'Design-notes.pdf',notice:'File prepared locally. Demo complete.'}:{active:0,reveal:0};}

 const {showcaseTime,...incoming}=props;const merged={...settings,...incoming};
 return <div style={{width:"100%",minWidth:0}}><Component {...merged} state={showcaseTime===undefined?incoming.state:showcase(showcaseTime)} seeking={showcaseTime!==undefined||incoming.seeking}/></div>;
