Introduction — Why reactive-button and when to use it

Building great UX around actions means handling latency, feedback, and edge cases. A button that remains clickable while an API call runs or that provides ambiguous feedback hurts conversion. The reactive-button component standardizes common patterns (loading spinner, disabled state, success/error animations) so you don’t reimplement the same logic on every form or CTA.

Whether you’re shipping a submit button, an inline action, or a networked CTA, reactive-button abstracts state transitions so your UI is predictable, accessible, and animated out of the box. It supports promise-based handlers and manual state control, which makes it flexible for synchronous, async, and optimistic UI flows.

This guide covers installation, basic and advanced usage, loading and state patterns, animations, accessibility considerations, and customization techniques that scale across apps.

Installation & setup

Install the package with your preferred package manager. The component works with React 16.8+ (hooks) and integrates into any build toolchain (Webpack, Vite, CRA).

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

After installation, import the component and styles (if the package exposes them) and include the button in your component tree. You can use it in controlled mode (manually toggling states) or in promise mode where the library infers states from a returned promise.

For a practical walkthrough and advanced examples, see the tutorial linked below. It demonstrates getting started, animations, and real-world patterns:

Basic usage and example

Here’s a minimal example showing promise-based handling. This is the fastest way to get loading/success/error states without manual state management.

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

function SaveButton() {
  const handleSave = () => {
    // return a promise: reactive-button will show loading until it resolves/rejects
    return fetch('/api/save', { method: 'POST' })
      .then(res => {
        if (!res.ok) throw new Error('Save failed');
        return res.json();
      });
  };

  return (
    <ReactiveButton
      idleText="Save"
      loadingText="Saving..."
      successText="Saved"
      errorText="Try again"
      onClick={handleSave}
      color="blue"
      rounded
    />
  );
}

This pattern keeps your click handler clean — return a promise and let reactive-button handle the lifecycle. You can also supply synchronous handlers; if they return nothing, use manual state props (see next section).

Props like idleText, loadingText, and color options make rapid iteration simple. The component exposes callbacks for lifecycle events (onSuccess, onError, onLoading) so you can trigger side effects without coupling logic to the button internals.

Button states, loading UX, and state management

Common states: idle, loading, success, error, disabled. Reactive-button maps them to affordances and animations. Use promise mode for async flows or set the state manually for greater control (for example, optimistic updates or complex multi-step interactions).

Manual control pattern example:

const [state, setState] = useState('idle');

<ReactiveButton
  state={state}
  onClick={() => {
    setState('loading');
    apiCall()
      .then(() => setState('success'))
      .catch(() => setState('error'));
  }}
  idleText="Send"
  loadingText="Sending..."
/>

Design tip: always provide an accessible label and consider disabling the button during critical operations to prevent duplicate requests. If you allow repeated clicks, debounce or queue requests on the server side and provide clear feedback for each click.

Customization, styling, and animations

Styling approaches: CSS-in-JS, plain CSS, Tailwind utilities, or styled-components all work. reactive-button exposes className or style props so you can override visuals. For animations, the library often includes built-in transitions; otherwise wrap the component in motion libraries like Framer Motion for custom effects.

Example: add a success checkmark animation using CSS classes or an inline SVG. Keep animations short (200–500ms) to avoid delaying the user’s next action. Micro-interactions should communicate result, not interrupt flow.

Accessibility and motion: prefer reduced-motion respects and ensure color contrast for success/error states. Use ARIA attributes like aria-live="polite" for state messages and aria-disabled when disabling instead of removing interactivity unexpectedly.

Advanced patterns: composition, optimistic UI, and testing

Compose reactive-button with higher-order logic for patterns like debounced actions, batch operations, or chained promises. For optimistic UI, set the button to success immediately and roll back on error — the component’s manual state control makes this straightforward.

Testing: unit-test click flows by mocking the promise returned from the onClick handler and asserting that the component shows loading and then success or error states. In integration tests, stub network calls and verify ARIA attributes and disabled behavior.

Performance note: the button itself is lightweight. Avoid heavy computations inside the onClick handler; offload to web workers or backend. For many actions across lists, memoize handlers and prefer stable props to prevent unnecessary re-renders.

Integration tips and common pitfalls

Pitfall: forgetting to return a promise — the button will not detect completion. Solution: either return the promise or control state manually. Pitfall: conflicting styles from global CSS; scope styles with BEM or CSS modules.

For analytics, fire events in lifecycle callbacks (onSuccess/onError) rather than inside the UI handler, which keeps tracking logic separate from UI responsibilities.

Accessibility checklist

Always ensure your button has clear text or an aria-label. When the state changes, announce it to screen readers with aria-live regions or role=”status”. Don’t rely on color alone to communicate success or error—use icons or text.

Keyboard interactions: ensure the button can be focused and activated with Enter/Space. For long-running operations, consider a cancel option or allow background processing with status updates.

Motion: respect prefers-reduced-motion. Provide alternatives if animations convey crucial information, such as switching to text-only confirmations when motion is reduced.

FAQ

How do I install reactive-button in my React project?

Install via npm or yarn: npm install reactive-button or yarn add reactive-button. Then import the component where needed and supply either a promise-returning onClick or a controlled state prop.

How do I implement loading and success states?

Return a promise from onClick and use props like loadingText and successText. For manual control, pass a state prop set to ‘loading’, ‘success’, or ‘error’ and toggle it from your component logic.

Can I customize animations and styles?

Yes. Use the component’s className/style props or wrap it with CSS-in-JS/styled-components. For custom motion, integrate with Framer Motion or CSS keyframes and respect reduced-motion preferences.
