React Progress Bar Animation: Interactive Steppers & Spring Gauges
Linear progress bars often feel mechanical when tied directly to raw percentages. ExodeUI transforms React progress bars into responsive, organic meters with real harmonic spring physics. When progress values change from 20% to 75%, ExodeUI smoothly calculates mass, tension, and damping curves, avoiding awkward teleportation or robotic CSS transition delays. Ideal for file upload meters, onboarding checklists, and checkout wizards.
Runnable ExodeUI React Code Example
Production ReadyImport the ExodeUICanvas component directly into your React application tree. Wire states, triggers, and parameters declaratively:
import React, { useState } from 'react';
import { ExodeUICanvas } from 'exodeui';
export function SteppedProgressBar({ step, totalSteps = 4 }) {
const percentage = (step / totalSteps) * 100;
return (
<div
role="progressbar"
aria-valuenow={percentage}
aria-valuemin={0}
aria-valuemax={100}
className="progress-container"
>
<ExodeUICanvas
src="/scenes/spring-progress-bar.json"
stateMachine="ProgressMachine"
inputs={{
"targetPercentage": percentage,
"springTension": 160,
"springDamping": 14
}}
/>
</div>
);
}Frequently Asked Questions about animated progress bar
How does harmonic spring physics improve progress bar UX?
Standard CSS transitions use fixed durations that feel either sluggish on small updates or jarringly fast on large leaps. ExodeUI’s spring physics calculate velocity proportionally to the distance traveled, resulting in natural, responsive motion.
Can ExodeUI progress bars show intermediate milestone checkmarks?
Yes. State machine layers can fire milestone animations (e.g. popping a checkmark badge or emitting a confetti sparkle) whenever the progress value crosses specific numerical thresholds.
Does the progress bar support indeterminate loading states?
Yes. You can switch between an indeterminate looping pulse state and a determinate numerical progress state using a simple boolean input.
How do I ensure accessibility compliance with ARIA progressbar?
Set role="progressbar", aria-valuenow, aria-valuemin="0", and aria-valuemax="100" on the wrapping container so assistive screen readers announce incremental progress accurately.
