Getting Started

1. Add ebook files

Place your ebook files inside the project's public/uploads directory. The server recursively scans this directory and uses its folder structure to determine book types and categories.

For example:

public/uploads/
├── Books/
│   ├── Fiction/
│   │   └── Example Novel.epub
│   └── History/
│       └── Chinese History.pdf
├── Papers/
│   └── Economics/
│       └── Example Paper.pdf

The server automatically generates /books.json and uses it to populate the library.

For better automatic metadata detection, use a filename format such as:

Book Title - Author.pdf
Book Title - Author.epub
Book Title - Author.mobi

The reader can extract the title, author, and category information from the filename and directory structure.

2. Install dependencies and start the server

npm install && npm start

Then open the following address in your browser:

http://localhost:3000

Deployment Notes

• The project is suitable for local deployment on a NAS, home server, or private cloud.
• When using a static hosting service, make sure files under public/uploads are available to the web server.
• For remote deployment, verify directory permissions and ensure that the configured file paths remain consistent.
• Do not expose personal or copyrighted ebook files to the public internet without proper authorization.
