Badass JavaScript

PDF.js - Create PDFs in JavaScript

Marak Squires has released PDF.js, which lets you create PDFs in JavaScript, either in the browser or on the server with Node.js.  It has a simple API that you can use to add pages and text (image support is coming soon) to your PDF documents.  In the browser, PDFs are exported through data URIs, and on the server they can be written to files.  Below is an example of the API in use.

/* create the PDF document */

var doc = new pdf();
doc.text(20, 20, 'hello, I am PDF.');
doc.text(20, 30, 'i was created in the browser using javascript.');
doc.text(20, 40, 'i can also be created from node.js');

/* Optional - set properties on the document */
doc.setProperties({
  title: 'A sample document created by pdf.js',
  subject: 'PDFs are kinda cool, i guess',        
  author: 'Marak Squires',
  keywords: 'pdf.js, javascript, Marak, Marak Squires',
  creator: 'pdf.js'
});
      
doc.addPage();
doc.setFontSize(22);
doc.text(20, 20, 'This is a title');
doc.setFontSize(16); 
doc.text(20, 30, 'This is some normal sized text underneath.');

var fileName = "testFile"+new Date().getSeconds()+".pdf";
var pdfAsDataURI = doc.output('datauri', {"fileName":fileName});

Nice work, Marak!  It was only a matter of time.  You can check out a demo here, and get the code on Github.
