Managing a collection of eBooks often means dealing with multiple EPUB files scattered across folders. If you want to build an online library, an eBook converter, or a digital publishing platform, merging these EPUB files into a single file can dramatically simplify your workflow. In this tutorial, you’ll learn how to merge EPUB files programmatically in Node.js using the powerful Node.js REST API. It helps you automate eBook mergers in your applications, replacing the hectic and error-prone manual processing.

Steps to Merge EPUB Files Using Node.js

1. Import and set up GroupDocs.Merger Cloud Node.js SDK
2. Obtain API credentials and initialize the DocumentApi with them
3. Configure the source EPUB files to merge from the cloud storage
4. Define the EPUB merging options with JoinOptions
5. Create an EPUB file joining request using JoinRequest
6. Process the request to merge two EPUB files using the join() method

The outlined steps make merging EPUB documents simple and efficient. With the cloud-powered REST API, publishing tasks such as combining chapters, collections, or serialized content into a unified readable file become easier than ever. Developers can seamlessly join two EPUB files in the cloud without installing third-party software. Your document merger Node.js apps work across Windows, macOS, and Linux for universal deployment. The Cloud API’s flexibility enables integration into web platforms, content management systems, and digital libraries.
