Why use reactive-button in your React app?

Buttons are tiny UI elements with big responsibilities: they must communicate status, handle async flows, and remain accessible. reactive-button packages common button state patterns (loading, success, error) and neat animations into a plug-and-play component so you don’t reinvent the wheel for each async action.

Instead of manually toggling CSS classes and juggling booleans across components, reactive-button centralizes state transitions and labels while exposing props for customization. That reduces boilerplate, improves UX consistency, and helps you ship faster.

It’s especially helpful for forms, API calls, and flows where users expect instant feedback (e.g., saving, submitting, confirming). Use it when you want a reliable, animated button with minimal wiring—and graceful fallbacks when JavaScript is slow or disconnected.

Installation & quick start

Install from npm or yarn and import the component into any React file. The package is published on npm and straightforward to add to an existing project:

npm install reactive-button
# or
yarn add reactive-button

Then import and use it. The simplest implementation reacts to a click and uses internal states: idle, loading, success, error. This pattern integrates well with async functions and promises.

import React from 'react';
import ReactiveButton from 'reactive-button';

function SaveButton() {
  const handleClick = async () => {
    // replace with your async task
  };

  return (
    <ReactiveButton
      onClick={handleClick}
      idleText="Save"
      loadingText="Saving..."
      successText="Saved"
      errorText="Error"
    />
  );
}

Practical examples: loading, success, and error states

reactive-button shines when your onClick handler returns a promise. The component can automatically show a loading animation until the promise resolves, then switch to success or error. This pattern matches the mental model users expect from modern apps.

Example: a button that calls an API, shows loading while awaiting, and then displays success for a short time.

function ApiActionButton() {
  const handleApi = () => {
    return new Promise((resolve, reject) => {
      setTimeout(() => resolve('ok'), 1500);
    });
  };

  return (
    <ReactiveButton
      onClick={handleApi}
      idleText="Submit"
      loadingText="Submitting..."
      successText="Done"
      errorText="Try again"
      color="blue"
    />
  );
}

If you need manual control (for complex flows), you can manage the state via props and callbacks: set initial state, call setState(‘loading’) in your handler, then set to ‘success’ or ‘error’ programmatically. This hybrid approach is useful when you have multi-step client-side validation before contacting the server.

Finally, use the built-in callbacks for side-effects: onSuccess, onError, and onCompleted hooks let you trigger notifications, route changes, or analytics once the button resolves—keeping UI logic co-located and tidy.

Customization, styles, and animations

reactive-button exposes props to adjust size, color, rounded corners, shadow, and animation types. You can override styles with CSS if you need pixel-perfect design alignment—either target the component’s class names or wrap it in a styled container.

Basic props you’ll see across implementations include idleText, loadingText, successText, errorText, color, size, rounded, and animation. Use these to craft consistent micro-interactions without writing keyframe animations yourself. Want to swap the spinner for a custom SVG? Pass a custom child or override CSS animations.

Performance tip: prefer CSS animations over heavy JS-based transitions for frequent interactive elements. When you do need JS hooks, debounce rapid state toggles to avoid flicker, and keep animations brief (200–600ms) for snappy UX.

Accessibility, testing & best practices

Good button UX isn’t just visuals; it’s keyboard focus, ARIA states, and predictable behavior for assistive tech. Ensure reactive-button exposes an accessible role and uses aria-live for dynamic labels during loading. If it doesn’t by default, wrap it with an aria-live region or add aria-busy on the parent while loading.

Testing strategy: write unit tests for the state transitions (idle → loading → success/error) and integration tests that assert the button disables during async tasks. In E2E tests, ensure your test harness can wait for the success state or inspect network calls rather than relying on arbitrary timeouts.

Production checklist: provide fallback labels for low-bandwidth scenarios, ensure color contrast for all states, and avoid long success animations that feel sluggish. Keep labels concise and consistent with voice search intents (e.g., “Save”, “Submitting”, “Saved”).

Integration patterns & advanced tips

Use reactive-button as a single-responsibility component: it handles button visuals and state; keep business logic (data fetching, validation) in hooks or higher-level components. That separation simplifies testing and reuse across forms and dialogs.

For forms with multiple async inputs, prefer per-action reactive buttons rather than a global spinner. Users need contextual feedback close to the action they triggered. For complex multi-step processes, chain reactive-button states with a state machine (XState) for predictable flow control.

When building a design system, wrap reactive-button into a thin, branded adapter that enforces your tokens (colors, radius, animation durations). That wrapper makes it easy to swap implementations later without changing the app codebase.

Quick featured-snippet: Install & use reactive-button (3 steps)

1. Install: run npm install reactive-button or yarn add reactive-button.

2. Import & render: import ReactiveButton from 'reactive-button' then render with <ReactiveButton onClick={asyncHandler} />.

3. Return a Promise: have your click handler return a Promise (or use async/await). reactive-button will show loading and then success/error based on resolution.

FAQ

How do I install reactive-button in React?

Install via npm (npm install reactive-button) or yarn (yarn add reactive-button), import it with import ReactiveButton from 'reactive-button', and place it in your JSX. For a step-by-step guide, see the reactive-button tutorial.

How do I create a loading button that handles async actions?

Pass an async function (or one that returns a Promise) to the button’s onClick. reactive-button displays a loading state while the Promise is pending and automatically switches to success or error when it resolves or rejects. Example: <ReactiveButton onClick={async () => await apiCall()} loadingText="Working..." />.

How can I customize animations and states?

Use the component props for text, color, size, and animation preferences. For deeper control, override the CSS classes or wrap the component in a styled adapter that applies your design tokens. Keep animations short (200–600ms) for snappy UX and add accessible ARIA attributes if you provide dynamic content.
