How to reproduce the issue on Safari (12.1.2)
Run ng build --prod
and then navigate to the folder ./dist/ng-cli-safari-issue
. Serve this folder over http
using your favorite http server, for example using the npm packages http-serve
or live-serve
. Open the site on Safari and inside the Web Inspector window look at the Network tab about the JS files being loaded. As you see the ES5
as well as the ES2015
bundles have been loaded altogether as shown by the screenshot below:
One possible way to remedy this behaviour under Safari seems to be through through this commit. That's duplicating all the script
tags inside a given index.html
using the type=module
and nomodule
attributes.
