external sourcemaps

[tnguyen14]

Is there a way to generate external sourcemaps with this plugin?

Nop, but you can use Exorcist to externalize the inlined sourcemap from the bundle.

I was able to extract it using grunt-external-sourcemap, but unfortunately it doesn't work when watch: true.

[tleunen]

Running exorcist in the postBundleCB should work.. Did you try that?

[tnguyen14]

@tleunen do you have an example of how that config would look like?

[tleunen]

Hmm, the problem is that inside postBundleCB, the destination file is not created yet.
But what you can do is, based on the string buffer, get the inlined sourcemap, replace it by the reference to another file, and write the sourcemap inside another file.

If there were a hook to run something when the bundle is complete, you could run grunt-external-sourcemap but unfortunately, it's not the case.

Why would you like to get the sourcemap in another file while using watch: true?

[tnguyen14]

Yeah that's a great question. I personally wouldn't mind if it's inline. However, in the office, we use Eclipse as the company standard IDE and it tends to crash when trying to open a compiled JS file with inline sourcemaps.

[tleunen]

I think your best bet is to let the sourcemap inside the bundle, and then run another task to extract the sourcemap from the bundle.

So try to use grunt-contrib-watch to watch your bundle file, and as soon as the file changed, run grunt-external-sourcemap to extract it.
