(Enhancement) Please add source maps for minified code

[kenaniah]

http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/ gives a quick overview for the uninitiated.

Essentially, usage of source maps should aid in the debugging efforts of production code as one would no longer have to switch back to highcharts.src.js just to track down errors.

I'd like to add my support for this enhancement. Given that the issue has been open for nearly two years, I'm not optimistic, but hey, maybe it just got lost in the shuffle?

Auto generating a sourcemap for the minified code should be as simple as passing a flag to Closure Compiler...

[TorsteinHonsi]

To add it to code.highcharts.com and our zip packages we should

• Pass the flag to Closure Compiler in the compile target.
• For that we would need names for the map files, added in the minify target.
• In the dist target, copy the files over to distribution folders.

We are working on this, in fact we are already uploading the maps to code.highcharts.com (http://code.highcharts.com/highcharts.js.map). What's left is to add the reference to the map from the minified files.

[e-cloud]

sourcemap is still unavailable now. no reference added to the minified files.

@jon-a-nygaard What's the status?

[olejorgenb]

In the npm package we're using (6.0.6) there is source maps, but maybe that's added by a third party?

Unfortunately I haven't succeeded getting webpack to "forward" these maps so it's not much help :(

@jon-a-nygaard Anything new?

[scott-ho]

It's a 5.5 years issue. And no fix available. Does highcharts team take this seriously? For commercial users, that's really bad experience.

[jon-a-nygaard]

v6.1.3 is now published with fixed source maps which is detected by the browser.
Apologies for the delay.

[scott-ho]

Thanks anyway.
