I wanted to create a global variable which is of type boolean, I wanted to utilize the same variable in multiple components (Without using Service).To be precise I also wanted to capture the variable value from any component if it is changed in other components.

There are few options to do it.

1. Environment variables : Declare the variable in environment.ts. Do note that you need to replicate it across envionment.prod.ts and other environment files if you may have.
2. Injection Token : Create a custom injection token, and pass it as a provider in your Component or Module. Details
