I generate source maps for javascript files during minification. The map files are referenced using a relative URL from the minified JS files that sit next to the map files. Here is an example comment at the end of app-e47a6637.js:

//# sourceMappingURL=app-e47a6637.js.map

The source map resolution works as expected in Firefox. However, Chrome does not load the map files.

Additional information:

  • JS source maps are of course enabled in the settings.
  • I tried putting a proxy between Chrome and the server. Chrome does not even request the map files.
  • I use gulp-sourcemaps to generate the map files.
  • I don't want to use the workspace feature of Chrome. I just want it to display the original source files.

How can I enable source maps in Chrome?

  • Are your sourcemaps being served? ( can you view them if you point your browser directly at them? ) Another thing you might try is an 'empty cache and hard reload' I've noticed chrome seems to cache source stuff pretty deep. Commented Dec 7, 2015 at 16:57
  • @BenJamin Yes they are, otherwise it wouldn't work in Firefox. I can download the map files in both FF and Chrome. Clearing the cache also did not improve the situation. Commented Dec 8, 2015 at 7:21
  • is the Source Map URL correct? Commented Dec 8, 2015 at 21:53
  • @BenJamin I don't know if you saw my comment: "... otherwise it wouldn't work in Firefox. I can download the map files in both FF and Chrome." So yes, the URL is correct. Commented Dec 9, 2015 at 8:13
  • In the web inspector, under settings, is "Enable JavaScript source maps" checked? Commented Dec 9, 2015 at 8:20
