Mangled names in debugger with source maps
debugging, google-chrome, grunt-contrib-uglify, javascript, source-maps
Solution
As noted by @rd5, this is issue 327092 in Google Chrome, reported on 2013-12-09.
As of 2018-07-01, the issue is still unresolved.
Problem
The debugger in Chrome/Safari does not show unmangled variable names when using source maps generated with grunt-contrib-uglify. Source code is displayed and debugged correctly. I have verified that the source map contains the variable names. Is this a bug in uglify? Original source: ``` // two function two() { var test = "test"; console.log("this is a " + test); } ``` Generated source: ``` function two(){var a="test";console.log("this is a "+a)} //# sourceMappingURL=all.min.js.map ``` Source map: ``` { "version": 3, "file": "all.min.js", "sources": ["../src/two.js"], "names": ["two","test","console","log"], "mappings":";;AAEA,QAASA,OAEL,GAAIC,GAAO,MAEXC,SAAQC,IAAI,aAAeF", "sourceRoot":"../" } ```
