[Pkg-javascript-devel] Bug#922824: sourceMappingURL in minified js seems to point to the wrong location

Package: libjs-bootstrap4
Version: 4.2.1+dfsg2-2
Severity: normal
Hello,
Thank you for packaging bootstrap.
The minified bootstrap4 javascript file is currently distributed in
these two paths:
/usr/lib/nodejs/bootstrap/dist/js/bootstrap.min.js
/usr/share/javascript/bootstrap4/js/bootstrap.min.js
and they come with a sourceMappingURL of:
//# sourceMappingURL=dist/js/bootstrap.js.map
If I make one of those paths accessible on the web and include bootstrap
with something like:
<script src="{{static_url('bootstrap4/js/bootstrap.min.js')}}"></script>
Then I see the browser make this failed request on my HTTP server:
404 GET /static/bootstrap4/js/dist/js/bootstrap.js.map
I tried to look up how sourceMappingURL works:
https://stackoverflow.com/questions/38427991/which-is-the-base-url-of-sourcemappingurl-relative-from-html-or-js
and it looks to me like bootstrap.min.js should contain something like
"sourceMappingURL=bootstrap.js.map" to have it being found alongside the
.min.js version.
