LeanPub Compilation and Sanitizing Tool Written in Node.js

LeanPub Tool — Node.js script for sanitizing and compiling a book’s manuscript. LeanPub uses multi-file book format and a special markdown markup (that confuses Marked app). I found that to convert to MS Word (for editing and other needs) this workflow is the best: 1. run leanpub-tool.js with node.js (node leanpub-tool.js) 2. open file in Marked app and convert to HTML 3. open HTML in MS Word and enjoy.

LeanPub is an awesome publishing platform, but often we need to communicate with other  team members involved in the book production, e.g., content and copy editors. In such times, I’ve learned that Guy Kawasaki was right — when we suggested in his book APE: Author, Publisher, Entrepreneur — that author must use MS Word!

The problem is that LeanPub uses multi-file book format and a special markdown markup (that confuses Marked app). I was wrapping up a new revision of the Rapid Prototyping with JS book and previous experience of handing a txt file to an editor was poor. Luckily, Node.js came to help! Through some trail and error attempts, I found this workflow to be the best for converting LeanPub manuscript to a one MS Word file (for editing and other needs):

  1. Run leanpub-tool.js with Node.js (node leanpub-tool.js)
  2. Open file in Marked app and convert to HTML
  3. Open HTML in MS Word and enjoy.

The full code of leanpub-tool.js which is also available at https://gist.github.com/azat-co/5674684:

var fs = require('fs');
//change these to YOUR filenames
//probably we can read it from Book.txt but I was too lazy to implement it :-) and somebody might want to compile only sertain parts of the book
var book =[
var sanitizeText = [
  "I>## Note",
  "T>## Tip",
  "W>## Warning",
var str = '';
//read files
  str +=  fs.readFileSync(chapter,'utf8');
//sanitize LeanPub specific Markdown tags
//  console.log(text)
  //this loops through while there is not matches
  while (new RegExp (text).test(str)) {
    str = str.replace(text,'','gm')
//write output to a file

  1. Howdy! Quick question that’s totally off topic. Do you know how to make your site mobile friendly? My blog looks weird when browsing from my iphone4. I’m trying to find
    a template or plugin that might be able to resolve this problem.
    If you have any suggestions, please share. Thank you!
