This question was answered with configuration for webpack. I am trying to get source maps working myself and wondering why chrome (and firefox) are not respecting the comment

//# sourceMappingURL=main.js.map

I thought I should see a network request to the server in devtools for the map file, right? Why is that not happening and how do we modify the main.js file created by webpack OR the *.js file created by our other tools such that it works without configuring chrome developer tools like was done before. I figure since both firefox and chrome are not working, there must be some new standard I am missing? (but not sure since webpack does not seem to do it properly?)

Firefox says it should be just do the above here -> https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Use_a_source_map
