bug: V4 angular 8: Prod build "page not found" on refresh #19020

Bug Report

Ionic version:

[x] 4.x

Current behavior:
I use my app, the URL now reflects my current page. I refresh or load that full url:

  • the dev "ionic serve" works properly
  • the prod and release builds can't start

Expected behavior:

  • if my url contains a route, refreshing or accessing a bookmark shouldn't crash ("not found"), it should rather display the right page/component/route.
  • prod and prod release should both work

Steps to reproduce:

  • use the latest ionic
  • ionic start app-test
  • use the navigation or tabbed template
  • cd app-test
  • ionic build --prod (–release is not necessary)
  • serve/deploy www
  • access root url -> works
  • ensure that the route has been appended (like “/home”)
  • refresh
  • crash

Related code:
See the following snapshot in GitHub:

  • it includes the attempt to eager load a route.
  • the package.json versions are frozen to avoid side effects from ^ and ~

Other information:

  • tested with the same node/npm/ionic/cli on a W10 and an OSX Mojave, behavior is unchanged

Sorry, my mistake - I forgot the rewrite rule:

Configure as a single-page app (rewrite all urls to /index.html)?" Enter "Yes".
