How to properly organize the pickup of the config from the backend at the beginning of the download?

Question

Angular

Good day,
There is a configuration file in the .json format on the backend, which is used everywhere in the project (back, api, current front). Now I am transferring a project from angular 1.5 to angular 2 and the question arose, how would it be most correct to organize a request to this file at the very beginning of the download? So that under certain configurations in a file, different actions are performed after a full load?
