Error Geek

Probem: I am trying to serve the app via configuration for prod in Angular 6 using below command. ng serve --configuration=prod But it gives me below error : Configuration 'prod' could not be found in project 'platform-ui' . Error : Configuration 'prod' could not be found in project 'platform-ui' . Solution : If you look at your angular.json file, you'll see that you have finer control over settings for each configuration. Now look for serve tag in json "serve" : { "builder" : "@angular-devkit/build-angular:dev-server" , "options" : { "browserTarget" : "platform-ui:build" }, and add configuration for your custom server like this : "configurations" : { "production" : { "browserTarget" : "platform-ui:build:production" ...

The Location class has prepareExternalUrl() that takes base href into account. You can also try to inject  constructor( @ Inject(APP_BASE_HREF) href:string){} It seems APP_BASE_HREF can't be injected anymore without explicitly providing it. PlatformLocation  Provides more details about the URL Service available in Angular 5+ apps that makes it easy to interact with the current URL path. Service can come-in really handy when coupled with the router to perform certain operations. you can get URL like this. constructor(platformLocation: PlatformLocation) { console.log((platformLocation as any).location); console.log((platformLocation as any).location.href); console.log((platformLocation as any).location.origin); }
