Can I dynamically change the deploy url when app start ?

I know that I can use the angular-cli to config the deploy-url like --deploy-url http://xxxxxxx/, but when I want to change the deploy-url I must to build again. I want to write somethings global like

<script type="text/javascript">  
    window['setting'] = {
      'siteurl':'https://xxxxxxxx/'
    }
</script>

in the root html. And Can I set the deploy-url use the already exist variable when the app start so that I can change the url without build again?

I don’t know if anyone’s reading this topic before advising anything, but the main question is about “changing deployUrl” when app is already running (in runtime). Not on the stage of building app with angular-cli, as @RajnishKatharotiya @ctrl-brk are proposing.

I think this issue is a duplicate of https://github.com/angular/angular-cli/issues/3855. There are suggestions there on how you can setup runtime configuration.
