How to add common api url link to environment page in angular

step1) add url to your environment.ts.
 
export const environment = {

production: false,
apiUrl: 'www.localurl.com'
};

step2) add same url to your environment.prod.ts
export const environment = {
production: true,
apiUrl: 'www.productionurl.com'
}; Now when you build for production like ng build --env=prod it will automatically use production url and when you build for local use like ng build it will use local url.
