Troubleshooting minified JavaScript in live environment

Trying to wrap my head around AngularJS and Grunt. In my GruntFile.js, I have set up two grunt tasks for development and production. In production, I am using uglification to combine multiple js files into one.

I am in need of some advice or tips on how to debug uglified javascript code in production if any issues arise. I have tried searching online and asking my colleagues for help, but so far, no luck. That's why I am turning to stack-overflow for assistance.

Is there a method to de-uglify scripts in production on-the-fly for debugging purposes, or perhaps a configuration that allows me to switch between uncompressed and compressed files for debugging and post-production purposes?

The responses provided here are truly helpful. Thank you.

If there are any additional methods or tips you can share, please feel free to do so.

Answer №1

Attempting to troubleshoot minified code without utilizing source maps can drive you insane. Perhaps it would be more beneficial to reconstruct the code rather than attempting to resolve issues within minified code?

Answer №2

While I primarily use Chrome, I believe Firefox offers a similar feature:

That small brackets icon at the bottom of the script panel automatically formats the code. This feature works well even with messy or minified code.

It's a convenient solution for quick tasks, but relying on it may lead to issues. It's advisable to use Source Maps instead. Check out @TechGuru's explanation for more details. It's funny how we both shared the same resources.
