Create a new ebook

Each ebook lives inside the ebooks directory.

ebooks/
  my-ebook/
    ├── ebook.ts
    ├── theme.ts

Example ebook:

export const myEbook = {
  id: "my-ebook",
  title: "Title",
  author: "Author",
  sections: [
    {
      id: "intro",
      title: "Introduction",
      blocks: [
        {
          type: "heading",
          level: 1,
          content: "Chapter title",
        },
        {
          type: "rich-paragraph",
          content: "Text content with **Markdown** support.",
        },
      ],
    },
  ],
};

Register the ebook:

export const ebookRegistry = {
  "my-ebook": {
    ebook: myEbook,
    theme,
  },
};

After registering it, the ebook will be available in the browser preview and export commands.

Theme presets

Predefined themes are available in ebook-engine/presets.ts.

Preset	Style
minimal	Clean and editorial
corporate	Formal and structured
modern	Expressive and balanced
documentation	Technical and highly readable

Use a preset:

import { presets } from "@/ebook-engine/presets";

export const theme = presets.corporate;

Override specific fields:

import { presets, extendPreset } from "@/ebook-engine/presets";

export const theme = extendPreset(presets.corporate, {
  colors: {
    accent: "#e63946",
  },
});

Content blocks

Text fields support Markdown formatting such as bold, italic, code, links, and strikethrough.

Block-level components like rich-paragraph, quote, highlight, note, warning, and action-box support full Markdown.

Inline contexts such as headings, list items, table cells, and captions render inline Markdown only.

Type	Description
rich-paragraph	Body text with Markdown support
heading	Section title, levels 1 to 3
quote	Styled pull quote
highlight	Short emphasized phrase or key takeaway
note	Tip or contextual explanation
warning	Critical or cautionary message
action-box	Highlighted call-to-action box
list	Bullet list
item-list	Labeled list with richer item styling
steps	Numbered step-by-step sequence
table	Tabular data with headers
code	Monospace code block
image-with-caption	Image with optional caption
divider	Visual separator
page-break	Forces a new page

Project goal

The goal of ebook-creator is to make ebook production more structured and programmable.

Instead of using visual editors or manually adjusting pages, you define the content, theme, and layout in code. The engine handles preview and export, making it easier to keep ebooks consistent, reusable, and version-controlled.
