## Where to use it

People click twice when nothing seems to happen. This button answers right away: it shows it is working, then confirms. Good for “Save changes” on a settings page, “Send message” on a contact form or “Apply coupon” at checkout. Idle, loading and done: those three states are what most forms need from a loading button.

In the demo the wait is simulated, so hook the success state to your real request. If saving can fail, add an error state too. Showing a check when nothing was saved does more harm than having no animation at all.

## Code

### React (Motion)

```tsx
import { useState } from "react";
import { AnimatePresence, motion } from "framer-motion";
import { Check, Loader2 } from "lucide-react";

interface LoadingButtonProps {
  color?: string;
  radius?: number;
  text?: string;
  /** Multiplica la velocidad de la carga simulada. */
  intensity?: number;
}

export default function LoadingButton({
  color = "#0071e3",
  radius = 24,
  text = "Save changes",
  intensity = 1,
}: LoadingButtonProps) {
  const [state, setState] = useState<"idle" | "loading" | "success">("idle");

  return (
    <motion.button
      type="button"
      className="flex min-w-36 items-center justify-center gap-2 px-6 py-3 text-sm font-semibold text-white shadow-lg"
      style={{
        backgroundColor: state === "success" ? "#0071e3" : color,
        borderRadius: radius,
      }}
      animate={{ scale: state === "loading" ? 0.97 : 1 }}
      onClick={() => {
        if (state !== "idle") return;
        setState("loading");
        setTimeout(() => setState("success"), 1500 / intensity);
        setTimeout(() => setState("idle"), 1500 / intensity + 1800);
      }}
    >
      <AnimatePresence mode="wait" initial={false}>
        {state === "idle" && (
          <motion.span
            key="idle"
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
          >
            {text}
          </motion.span>
        )}
        {state === "loading" && (
          <motion.span
            key="loading"
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
          >
            <Loader2 className="h-4 w-4 animate-spin" />
          </motion.span>
        )}
        {state === "success" && (
          <motion.span
            key="success"
            initial={{ opacity: 0, scale: 0.5 }}
            animate={{ opacity: 1, scale: 1 }}
            exit={{ opacity: 0 }}
            className="flex items-center gap-1.5"
          >
            <Check className="h-4 w-4" /> Done
          </motion.span>
        )}
      </AnimatePresence>
    </motion.button>
  );
}
```

I want to add the “Loading to success button” block (Buttons) from AIMRAN Library to my project.

## What it is
Click it and the label turns into a spinner, then into a check mark, before the button resets itself.

## Chosen settings
- Color: #0071e3
- Corner radius: 24px (from 0 to 24px)
- Text: "Save changes"
- Intensity: 1 (from 0.2 to 2)

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with React + TypeScript, with framer-motion for the animation and lucide-react for the icons. If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.

## Reference code
```tsx
import { useState } from "react";
import { AnimatePresence, motion } from "framer-motion";
import { Check, Loader2 } from "lucide-react";

interface LoadingButtonProps {
  color?: string;
  radius?: number;
  text?: string;
  /** Multiplica la velocidad de la carga simulada. */
  intensity?: number;
}

export default function LoadingButton({
  color = "#0071e3",
  radius = 24,
  text = "Save changes",
  intensity = 1,
}: LoadingButtonProps) {
  const [state, setState] = useState<"idle" | "loading" | "success">("idle");

  return (
    <motion.button
      type="button"
      className="flex min-w-36 items-center justify-center gap-2 px-6 py-3 text-sm font-semibold text-white shadow-lg"
      style={{
        backgroundColor: state === "success" ? "#0071e3" : color,
        borderRadius: radius,
      }}
      animate={{ scale: state === "loading" ? 0.97 : 1 }}
      onClick={() => {
        if (state !== "idle") return;
        setState("loading");
        setTimeout(() => setState("success"), 1500 / intensity);
        setTimeout(() => setState("idle"), 1500 / intensity + 1800);
      }}
    >
      <AnimatePresence mode="wait" initial={false}>
        {state === "idle" && (
          <motion.span
            key="idle"
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
          >
            {text}
          </motion.span>
        )}
        {state === "loading" && (
          <motion.span
            key="loading"
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
          >
            <Loader2 className="h-4 w-4 animate-spin" />
          </motion.span>
        )}
        {state === "success" && (
          <motion.span
            key="success"
            initial={{ opacity: 0, scale: 0.5 }}
            animate={{ opacity: 1, scale: 1 }}
            exit={{ opacity: 0 }}
            className="flex items-center gap-1.5"
          >
            <Check className="h-4 w-4" /> Done
          </motion.span>
        )}
      </AnimatePresence>
    </motion.button>
  );
}
```
