bookjen

Martin Shkreli's million-peso idea.

Bookjen is a Node.js script that generates a book based on a specified genre, number of chapters, and pages per chapter. It uses an AI language model to generate summaries and content for each chapter and page.

Features

• Generates a book summary, chapter summaries, and individual page content.
• Filters out unwanted headlines (e.g., "chapter," "page") from the content.
• Saves progress during execution to allow resumption if interrupted.
• Outputs the final book in both JSON and plain text formats.

Prerequisites

1. Node.js (v16 or newer)
2. NPM or Yarn
3. A .env file configured with required API keys for the askOpenRouter function.

Installation

1. Clone the repository or download the script.

2. Install dependencies:

   npm install

3. Ensure the required .env file exists with appropriate configuration. See example.env for reference.

Usage

node bookjen.js [genre/description] [chapters] [pages]

Arguments

• [genre]: The genre of the book (e.g., “fantasy,” “romance”).
• [numChapters]: Number of chapters in the book (integer).
• [pagesPerChapter]: Number of pages per chapter (integer).
• [llmModel]: The language model to use (default: sao10k/l3.3-euryale-70b).

Outputs

1. Progress File: Location: ./output/<filename>.json. Contains detailed summaries and content for all chapters and pages.

2. Final Book File: Location: ./output/<filename>.txt. Plain text file with the book content.

Key Functions

• removeHeadlinesFromPage(page): Removes unwanted lines (e.g., headers like “chapter” or “page”) from a page’s content.
• loadProgress(filePath): Loads progress from a saved file if available.
• saveProgress(progress, filePath): Saves the current state to allow resumption.
• outputBook(progress, filePath): Compiles and writes the final book to a text file.

Notes

• Generated filenames are sanitized and include the genre, chapter count, page count, and model name for easy identification.

Troubleshooting

• Invalid Arguments: Ensure all required arguments are provided and valid.
• API Errors: Verify the .env configuration and ensure the API key is valid.
• File Save Errors: Ensure the ./output directory can be created.

Todo

Better summarizing previous chapters/pages/etc so llm can pickup on shit.

Automatically pulling models from openrouter api, and using it to, say, populate a select.
