Can I re-construct the original JavaScript source file from a minified version and the corresponding source-map file?

Question

I am working on a project where I have to statically analyse JavaScript code. However, for a few libraries, I only have access to a minified version of the file and the corresponding source-map. Is there a method/technique with which I can generate the original file using these files?

Answer 1

I found a node.js library that can help do this: Maximize Corresponding github repo

Answer 2

If your objective is "just" to do a onetime re-construction of the original source code I did it using:

Online Source Visualization

1. use the "Custom" option
2. upload compiled file
3. upload source map file

Depending on filesize it may take a while to view the results.
