Is it possible to inject a service inside another service and vice versa at the same time?

Question

I have a real scenario in a real project where I need 2 services to access the properties and/or methods of each other. I\'m not an Angular expert so is it possible?

No. Circular dependencies are not resolved by angular's DI.

Also even systems that do support it, quite commonly are inconsistent e.g. commonjs https://nodejs.org/docs/latest/api/modules.html#modules_cycles will give you an empty object for a while.

Solution

Consider combining the two services into one. You can still move certain stuff (e.g. simple functions etc) out from the combined service if it becomes too much.
