Can I re-construct the original JavaScript source file from a minified version and the corresponding source-map file?
I found a node.js library that can help do this: Maximize Corresponding github repo
If your objective is "just" to do a onetime re-construction of the original source code I did it using:
Online Source Visualization
- use the "Custom" option
- upload compiled file
- upload source map file
Depending on filesize it may take a while to view the results.
