How to use global variables in nest.js?

[ChoGathK]

Taking configuration as an example, the Nest.js documentation advocates registering Config Modules and injecting them into other modules in a dependency injection way.

The benefits are obvious, and the dependencies and code are clear, but what if I have a nest.js project that needs to invoke the configuration information at startup? This actually caused me trouble.

My idea is to use a store (actually a closure) to manage all the variables that might be needed globally, the client-side link objects, registered at startup, and introduced when needed.

When corresponding variables are registered in this way, they can be introduced anywhere. The drawback is that you need to manage dependencies yourself.

With the above concept design of demo: https://github.com/sophons-space/nest-server.

Please e help me correct, I am still a rookie.
