epubreader-js

About the Reader

The epubreader-js application is based on the epub.js library and is a fork of the epubjs-reader repository.

Getting Started

Open up epubreader-js in a browser.

You can change the ePub it opens by passing a link to bookPath in the url:

?bookPath=https://s3.amazonaws.com/epubjs/books/alice.epub

Running Locally

Install node.js

Then install the project dependences with npm

npm install

You can run the reader locally with the command

npm run serve

Builds are concatenated and minified using webpack

To generate a new build run

npm run build

or rebuilding all *.js files

npm run prepare

Pre-configuration

The epubreader-js application settings is a JavaScript object that you pass as an argument to the Reader constructor. You can make preliminary settings in the file index.html. For example, this is what the default Reader initialization looks like:

<script type="module">
    import { Reader } from "./js/epubreader.min.js"
    const url = new URL(window.location)
    const path = url.searchParams.get("bookPath") || "https://s3.amazonaws.com/moby-dick/"
    window.onload = (e) => new Reader(path)
</script>

Let's say we want to disable the openbook feature, which is designed to open an epub file on a personal computer. This can be useful for integrating a public library into your site. Let's do this:

<script type="module">
    import { Reader } from "./js/epubreader.min.js"
    const url = "{{bookPath}}"
    window.onload = (e) => new Reader(url, { openbook: false })
</script>

Note that the {{bookPath}} replacement token is used to define the url string variable. This simple solution will allow you to set up a route to pass the target URL.
