Angular 8. Angular 9, Angular Most apps go through different stages before they go into production. These stages may be development, testing, staging, and production. We call these stages as Environment. For Example, while you build the app for production, we need our app to be optimized, minified and uglified. For development, we do not want any of them but want the app to log all kinds of debugging information. The Environment Variable are those variables, whose value changes as per the environment we are in.

This will help us to change some behavior of the App based on the environment. Or you do not want to send those log messages to console in the production environment. The Angular provides built-in support to configure and manage environment variables. The folder contains two files one in environment. The default is the development and uses the environment.

Run the app using the ng serve. This will build the app using the default or development environment variable. Using the production configuration switches the environment file to environment. We use ng build to build the app before distributing it.

Then modify your serve section to add a new configuration as well, pointing to the dev2 build configuration you just declared. This answer seems good. It is requierd not only to updated build configurations, but also serve ones. For Angular 2 - 5 refer the article Multiple Environment in angular. Note: Refer the same article for angular 6 as well.
