Try This :-

pages/_app.js

export default function MyApp({ Component, pageProps, router }) {
  return (
    <SwitchTransition mode='out-in'>
      <CSSTransition key={router.pathname} classNames='page' timeout={300}>
        <Component {...pageProps} />
      </CSSTransition>
    </SwitchTransition>
  );
}

global.css

.page-enter {
  opacity: 0;
  transform: scale(1.1);
}
.page-enter-active {
  opacity: 1;
  transform: scale(1);
  transition: opacity 300ms, transform 300ms;
}
.page-exit {
  opacity: 1;
  transform: scale(1);
}

.page-exit-active {
  opacity: 0;
  transform: scale(0.9);
  transition: opacity 300ms, transform 300ms;
}```
