```typescript
import { Epubook } from 'epubook';

const book = await Epubook.create({
  title: 'Complete Ebook',
  description: 'Ready for export',
  author: [{ name: 'Author Name' }],
  language: 'en-US'
});

const cover = await book.cover('./cover.jpg');
const chapter1 = book.page('chapter', { title: 'Chapter 1', content: 'Content here...' });
const chapter2 = book.page('chapter', { title: 'Chapter 2', content: 'More content...' });

book.toc(cover, chapter1, chapter2);

// Write the final EPUB file

```typescript
import { Epubook, XHTML } from 'epubook';

const book = await Epubook.create({
  title: 'Organized Novel',
  description: 'A well-structured ebook with sections'
});

const cover = await book.cover('./cover.jpg');

// Create multiple chapters
const intro = book.page('chapter', { title: 'Introduction', content: 'Welcome to this book...' });
const ch1 = book.page('chapter', { title: 'Chapter 1', content: 'First chapter content...' });
const ch2 = book.page('chapter', { title: 'Chapter 2', content: 'Second chapter content...' });
const ch3 = book.page('chapter', { title: 'Chapter 3', content: 'Third chapter content...' });
const epilogue = book.page('chapter', { title: 'Epilogue', content: 'Final thoughts...' });

// Simple flat table of contents
book.toc(cover, intro, ch1, ch2, ch3, epilogue);

// Alternative: Grouped table of contents with sections
book.toc(
  cover,
  intro,
  { title: 'Part One', list: [ch1, ch2] },
  { title: 'Part Two', list: [ch3] },
  epilogue
);
```

--------------------------------

### Construct XHTML with XHTMLBuilder

Source: https://context7.com/yjl9903/epubook/llms.txt

Utilize the fluent API of XHTMLBuilder to programmatically define document structure, metadata, and body content.

```typescript
import { XHTMLBuilder } from '@epubook/xml';

// Create an XHTML document programmatically
const builder = new XHTMLBuilder('text/chapter.xhtml');

builder
  .setTitle('My Chapter')
  .setLanguage('en')
  .appendStyleSheet('../styles/main.css')
  .appendBody({
    type: 'element',
    name: 'h1',
    attributes: {},
    children: [{ type: 'text', value: 'Chapter Title' }]
  })
  .appendBody({
    type: 'element',
    name: 'p',
    attributes: { class: 'intro' },
    children: [{ type: 'text', value: 'This is the introduction paragraph.' }]
  });

const result = builder.build();
// result.filename: 'text/chapter.xhtml'
// result.meta: { title: 'My Chapter', language: 'en' }
// result.content: Full XHTML string with proper namespaces
```

--------------------------------

### Add Images to Ebook Content with Epubook

Source: https://context7.com/yjl9903/epubook/llms.txt

The `image()` method registers images in the ebook's manifest. It accepts file paths or Uint8Array buffers and returns a Promise resolving to an Image resource for use in custom XHTML.

```typescript
import { Epubook } from 'epubook';
import * as fs from 'node:fs';

const book = await Epubook.create({
  title: 'Illustrated Guide',
  description: 'A book with images'
});

// Add image from file path
const diagram1 = await book.image('./images/diagram1.png');

// Add image from buffer
const imageData = fs.readFileSync('./images/photo.jpg');
const photo = await book.image(new Uint8Array(imageData), 'jpg');

// Images are now in the manifest and can be referenced in custom pages
```

--------------------------------

### Generate XHTML with JSX

Source: https://github.com/yjl9903/epubook/blob/main/packages/core/README.md

Use JSX syntax to construct XHTML nodes for book content.

```tsx
/** @jsxImportSource @epubook/xml */

import { XHTMLBuilder } from '@epubook/core'

const builder = new XHTMLBuilder()

const xhtml = builder
  .appendBody(<h1>Title</h1>)
  .appendBody(<p>This is a paragraph</p>)
  .build()
```

--------------------------------

### Extend Epubook with Custom Templates

Source: https://context7.com/yjl9903/epubook/llms.txt

Use the extend method to register custom page templates that return an XHTMLBuilder. These templates can then be instantiated using the page method.

```typescript
import { Epubook, XHTMLBuilder } from 'epubook';

const book = await Epubook.create({
  title: 'Custom Themed Book',
  description: 'Using custom page templates'
});

// Extend with custom templates
const extendedBook = book.extend({
  pages: {
    // Custom title page template
    titlePage: (file: string, props: { title: string; subtitle: string; author: string }) => {
      return new XHTMLBuilder(file)
        .setTitle(props.title)
        .appendBody({
          type: 'element',
          name: 'div',
          attributes: { class: 'title-page' },
          children: [
            { type: 'element', name: 'h1', attributes: {}, children: [{ type: 'text', value: props.title }] },
            { type: 'element', name: 'h2', attributes: {}, children: [{ type: 'text', value: props.subtitle }] },
            { type: 'element', name: 'p', attributes: { class: 'author' }, children: [{ type: 'text', value: props.author }] }
          ]
        });
    },
    // Custom dedication page template
    dedication: (file: string, props: { text: string }) => {
      return new XHTMLBuilder(file)
        .setTitle('Dedication')
        .appendBody({
          type: 'element',
          name: 'div',
          attributes: { class: 'dedication' },
          children: [{ type: 'element', name: 'p', attributes: {}, children: [{ type: 'text', value: props.text }] }]
        });
    }
  }
});

// Use custom templates
const titlePage = extendedBook.page('titlePage', {
  title: 'My Novel',
  subtitle: 'A Story of Adventure',
  author: 'Jane Author'
});

const dedication = extendedBook.page('dedication', {
  text: 'For my family, who always believed in me.'
});

const chapter1 = extendedBook.page('chapter', { title: 'Chapter 1', content: 'Story begins...' });

extendedBook.toc(titlePage, dedication, chapter1);
await extendedBook.writeFile('./custom-book.epub');
```

--------------------------------

### Add Cover Image to Ebook

Source: https://context7.com/yjl9903/epubook/llms.txt

Adds a cover image from a file path or buffer. This method automatically generates the cover XHTML and marks the image with the EPUB cover-image property.

```typescript
import { Epubook } from 'epubook';

const book = await Epubook.create({
  title: 'Adventure Novel',
  description: 'An exciting adventure story'
});

// Add cover from file path
const cover = await book.cover('./images/cover.jpg');

// Alternative: Add cover from buffer with explicit extension
import * as fs from 'node:fs';
const imageBuffer = fs.readFileSync('./images/cover.png');
const coverFromBuffer = await book.cover(new Uint8Array(imageBuffer), 'png');
```
