Dark Mode

When looking at implementing this be aware there is system, light and dark usually. Only if you go incognito do does the get switched off. I think it is held in LocalStorage somewhere

Components

Aceternity is a good place for NextJS components. You get the code and can change the components yourself. [here]

Changing Flex Direction

So wanted to see how to do this dynamically. And finally settled on this. In this example it monitors to the child to be less than 50% and sets the flex direction appropiately based off isChildMoreThan50

    const containerRef = useRef<HTMLDivElement>(null);
    const childRef = useRef<HTMLDivElement>(null);

    const [isChildMoreThan50, setIsChildMoreThan50] = useState(false);
    const [childWidthPct, setChildWidthPct] = useState(0);

    const updateFlexDirection = () => {
        const container = containerRef.current;
        const child = childRef.current;

        if (!container || !child) return;

        const containerWidth = container.offsetWidth;
        const childWidth = child.offsetWidth;

        console.log("Container Width:", containerWidth);
        console.log("Child Width:", childWidth);

        // Update state based on size comparison
        setIsChildMoreThan50(childWidth > containerWidth * 0.5);
        setChildWidthPct((childWidth / containerWidth) * 100);
    };

    useEffect(() => {
        const resizeObserver = new ResizeObserver(() => {
            updateFlexDirection();
        });

        const container = containerRef.current;
        const child = childRef.current;

        if (container) resizeObserver.observe(container);
        if (child) resizeObserver.observe(child);

        // Initial calculation
        updateFlexDirection();

        // Cleanup
        return () => {
            resizeObserver.disconnect();
        };
    }, []);

Lottie Buttons

Quite liked the lottie buttons but like most animation it will be boring once seen. Lottie waits for the state to be true.

    const [copied, setCopied] = useState<boolean>(false);

    const defaultOptions: Options = {
        loop: false,
        autoplay: false,
        animationData,
        rendererSettings: {
            preserveAspectRatio: "xMidYMid slice",
        },
    };

    return (

            <div className={`absolute -bottom-5 right-0 ${copied ? "block" : "block"}`}>
                <Lottie options={defaultOptions} isStopped={!copied} height={200} width={400} />
            </div>
