MyBook.Writer

A clean, modern library for creating e-books in EPUB and FB2 formats using .NET.

Installation

dotnet add package MyBook.Writer

Quick Start

Creating an EPUB Book

// Create a new EPUB builder
var builder = EpubBuilder.Create("My Book Title", "en")
    .WithAuthor("Author Name");

// Add a cover image
using (var coverStream = File.OpenRead("cover.jpg"))
{
    builder.WithCover(coverStream, "cover.jpg", "image/jpeg");
}

// Add chapters
builder.AddChapter(1, "Chapter 1", new List<string>
{
    "First paragraph of chapter 1.", 
    "Second paragraph with more text."
});

builder.AddChapter(2, "Chapter 2", new List<string>
{
    "Chapter 2 begins here.",
    "More content for chapter 2."
});

// Build and save
var writer = await builder.BuildAsync();
await writer.SaveToFileAsync("mybook.epub");

Creating an FB2 Book

// Create a new FB2 builder
var builder = FB2Builder.Create("My FB2 Book", "en")
    .WithAuthor("Author Name");

// Add cover
using (var coverStream = File.OpenRead("cover.jpg"))
{
    builder.WithCover(coverStream, "cover.jpg", "image/jpeg");
}

// Add chapters
builder.AddChapter(1, "Chapter 1", new[] { "Content for chapter 1" });
builder.AddChapter(2, "Chapter 2", new[] { "Content for chapter 2" });

// Build and save
var writer = await builder.BuildAsync();
await writer.SaveToFileAsync("mybook.fb2");

Using the Book Factory (Format-Agnostic)

// Create a book in any format with a simple interface
var format = BookFormat.Epub; // or BookFormat.FB2
IBookBuilder builder = BookFactory.CreateBuilder(format, "Book Title", "en");

// Use the fluent interface to configure the book
builder.WithAuthor("Author Name")
       .AddChapter(1, "Chapter", new[] { "Content" });

// Build and save
var writer = await builder.BuildAsync();
await writer.SaveAsStreamAsync(); // Get as stream
// or
await writer.SaveToFileAsync($"book.{format.ToString().ToLower()}");

Setting Up Logging

using Microsoft.Extensions.Logging;
using MyBook.Writer.Core.Services;

// Create a logger factory
using var loggerFactory = LoggerFactory.Create(builder =>
{
    builder
        .AddFilter("MyBook.Writer", LogLevel.Debug) // Set minimum level
        .AddConsole() // Log to console
        .AddDebug();  // Log to debug output
});

// Configure the book writer library to use our logger factory
loggerFactory.ConfigureBookWriter();
