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"

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
