Sometimes, you don't know what version of a project is deployed (WEB) or installed (PWA, Cordova, ...).
The backend project can also be different if the client isn't updated.
The idea is to offer an easy access to those values for Convertigo developers and global values can be easy to pickup anywhere in the application.
The builder can add code for this at generation time (depending on TPL ?) to declare global.projectVersionFront, global.projectName, global.projectBuildDate, global.projectGitSHA (if any), global.projectGitBranch (if any).
The SDK can declare a global.projectVersionBack using one of init calls.
