Installation

You can install the latest version using npm:

npm install page-flip

Or download bundle from Github

Usage

If you've installed the package from npm, you should import PageFlip from page-flip package, or just use <script/> tag:

<script src="{path/to/scripts}/page-flip.browser.js"></script>

To create a new PageFlip object:

import { PageFlip } from 'page-flip';

const pageFlip = new PageFlip(htmlParentElement, settings);

// or if you're using a script tag and page-flip.browser.js:
const pageFlip = new St.PageFlip(htmlParentElement, settings);

htmlParentElement - HTMLElement- root element, where the book will be created

settings: object - configuration object.

To draw on a canvas, use loadFromImages:

pageFlip.loadFromImages(['path/to/image1.jpg', 'path/to/image2.jpg' ... ]);

To load page from html elements - use loadFromHtml:

pageFlip.loadFromHtml(items);

For example:

<div id="book">
    <div class="my-page" data-density="hard">
        Page Cover
    </div>
    <div class="my-page">
        Page one
    </div>
    <div class="my-page">
        Page two
    </div>
    <div class="my-page">
        Page three
    </div>
    <div class="my-page">
        Page four
    </div>
    <div class="my-page" data-density="hard">
        Last page
    </div>
</div>

const pageFlip = new PageFlip(document.getElementById('book'), {
    width: 400, // required parameter - base page width
    height: 600, // required parameter - base page height
});

pageFlip.loadFromHTML(document.querySelectorAll('.my-page'));

Use data-density="hard" attribute to specify page type (soft | hard) and define flipping animation.

Config

To set configuration define these parameters when creating an object:

• width: number - required
• height: number - required
• size: ("fixed", "stretch") - default: "fixed" Whether the book will be stretched under the parent element or not
• minWidth, maxWidth, minHeight, maxHeight: number You must set threshold values ​​with size: "stretch"
• drawShadow: bool - default: true Draw shadows or not when page flipping
• flippingTime: number (milliseconds) - default: 1000 Flipping animation time
• usePortrait: bool - default: true Enable switching to portrait mode. !This mode uses cloning of html elements (pages)
• startZIndex: number - default: 0 Initial value to z-index
• startPage: number - default: 0 Page number from which to start viewing
• autoSize: bool - default: true If this value is true, the parent element will be equal to the size of the book
• maxShadowOpacity: number [0..1] - default: 1 Shadow intensity (1: max intensity, 0: hidden shadows)
• showCover: boolean - default: false If this value is true, the first and the last pages will be marked as hard and will be shown in single page mode
• mobileScrollSupport: boolean - default: true disable content scrolling when touching a book on mobile devices

Events

To listen events use the method on:

pageFlip.on('flip', (e) => {
    // callback code
    alert(e.data); // current page number
});

Available events:

• flip: number - triggered by page turning
• changeOrientation: ("portrait", "landscape") - triggered when page orientation changes
• changeState: ("user_fold", "fold_corner", "flipping", "read") - triggered when the state of the book changes
• init: ({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
• update: ({page: number, mode: 'portrait', 'landscape'}) - triggered when the book pages are updated (using the "updateFrom..." methods)

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

• getPageCount: number - Get number of all pages
• getOrientation: 'portrait', 'landscape' - Get the current orientation: portrait or landscape
