            <p>Page number: {props.number}</p>
        </div>
    );
});

function MyBook(props) {
    return (
        <HTMLFlipBook width={300} height={500}>
            <Page number="1">Page text</Page>
            <Page number="2">Page text</Page>
            <Page number="3">Page text</Page>

    return (
        <HTMLFlipBook
            /* props */

    )
}

Available events:

• onFlip: number - triggered by page turning
• onChangeOrientation: ("portrait", "landscape") - triggered when page orientation changes
• onChangeState: ("user_fold", "fold_corner", "flipping", "read") - triggered when the state of the book changes
• onInit: ({page: number, mode: 'portrait', 'landscape'}) - triggered when the book is init and the start page is loaded. Listen (on) this event before using the "loadFrom..." methods

Event object has two fields: data: number | string and object: PageFlip

Methods

  function DemoBook() {
        const book = useRef();

        return (
            <>
                <button onClick={() =>
                    book.current.pageFlip().flipNext()}>Next page</button>
