DWG converter for Node.js or Javascript library?

Question

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.

To display AutoCAD files (.DWG) in your AngularJS application and convert them to SVG or PDF format, you can consider using the following JavaScript libraries and tools:

1. `dwg2svg`: This is a JavaScript library that can convert DWG files to SVG format. It can be used in a Node.js environment. You can find it on GitHub: https://github.com/ytiurin/dwg2svg

2. `dxf-parser`: If you have DWG files in the DXF format, you can use this library to parse and convert them to a more manageable format in JavaScript. It does not directly convert to SVG, but it can help you extract the necessary information from the DWG files. Find it on GitHub: https://github.com/gdsestimating/dxf-parser

3. `svg2pdf`: Once you have converted the DWG files to SVG format, you can use this library to convert the SVG files to PDF format. It is a pure JavaScript implementation that runs in the browser. You can find it on GitHub: https://github.com/yWorks/svg2pdf.js

These libraries should help you achieve the conversion and rendering of DWG files in your AngularJS application. However, it's worth noting that the libraries mentioned may have limitations or require additional configuration to meet your specific requirements. Make sure to review their documentation and usage examples to understand how to integrate them effectively into your project.

Regarding hosting your application on Heroku, you may need to check if there are any restrictions or limitations on executing command-line utilities. If running the `cad2svg` utility is not possible on Heroku, you may need to explore alternative solutions using the JavaScript libraries mentioned above.

Remember to thoroughly test and validate the integration of these libraries into your application to ensure proper functionality and compatibility with your hosting environment.
