启用polyfill后，Angular 6路由器会在所有浏览器中崩溃应用程序？

Question

I have an angular 6 PWA, everything was good and working up until the point I enabled polyfills. Now when I run ngserve and try to navigate to another component it simply errors out and router outlet goes blank.

I have a similar app that works fine and to see if I ruined something with those polyfills - I just copy pasted the polyfills file there and with the same results.

I have also tried to run ng serve --prod but exact same result.

I have also commented out the polyfills except the reflect and zone as those were enabled by default and now the behaviour persists. Don't know what else to try on this one.

Answer 1

This was due to unsubscribing in a faulty way with onDestroy.

I was trying to unsubscribe to some subscriptions that I have created but for some odd reason that was erroring out and now that I've fixed this the routerLink works again.
