Desired functionality

Angular cli doesn't support functionality that would enable uploading sourcemaps to an external service.

Right now if you build with sourcemaps the .map files are generated and their filepath is referenced in the bundle as a comment. The only use case that supports is if you want to host the sourcemaps on the site which has a lot of disadvantages. In most cases you want to generate the sourcemaps and upload them directly to a service that requires them (i.e. sentry) so that they remain private.

Creating 2 independent builds - one with sourcemaps and one without - deploying the latter and uploading the former to a third party service does not work because the filepath reference to the .map file changes the bundle file hash and therefore the 2 builds have different filenames.

Desired functionality would involve passing an argument that would generate .map files in a separate directory under /dist without their filepath referenced in the bundle files as a comment.

Is there any word when/if something like this might be implemented?

I'll try and create a pull request for this feature this weekend.

webpack already contains this functionality encompassed in the hidden-source-map argument, I'll likely add a --hidden-source-map flag that sets devtool: hidden-source-map when building the webpack config. If anyone has a suggestion or feedback please let me know.

@NikolaJankovic any news on this feature? thanks!

[NikolaJankovic]

@templth I'm still working on having it done but its a lot more involved than I originally thought. I'll hopefully have a pull request in the next few weeks.

@NikolaJankovic if I can help you in anyway in this work, feel free to tell me!

Hi, this has been implemented and addressed in the latest beta (7.2.0-beta.0) with #13062

In your angular.json you can now use the hidden option, like

sourceMap: {
        hidden: true,
        styles: true,
        scripts: true
},
