Angular CLI build without index.html
In case anyone is still having the same issue, this is how I solved it.
In your angular.json:
"architect": { "build": { ... "configurations": { "production": { "index": "", // Do not copy index.html ...ng build --prod will not copy the HTML file, while ng build and ng serve will keep using it as expected.
You can concatenate commands in the scripts section of package.json. So append a delete command and create something like this (Windows command; adapt it to your system):
"scripts": { "build prod": "ng build --prod --env=prod -op dist && del dist\\index.html"}
