When we develop an application designed to run on multiple environments, we have to decide how to provide a configuration of appropriate variables depending on those environments

TLDR; 📕

• environment.ts is not the best way to provide an environment configuration
• do not introduce environmental configuration in build-time
• Special injection token called APP_INITIALIZER is used for convenient and effective external configuration providing
• I’ve prepared for you the minimal example which solves this problem by using APP_INITIALIZER. You can find it on StackBlitz
