I want to show AutoCAD-files (.DWG) in my AngularJS application and I'm using a Node.js backend for my application.

Are there any DWG libraries in Javascript?
Are there any DWG Node libraries to convert DWG files to a SVG / PDF / ...

I don't want to edit them; just show them online in my application.

The only that i could find was this :
http://etc.nkadesign.com/Download/Cad2svg

It's a linux command-line utility but I cannot use it since I want to
host my application on the Heroku platform.
