Providing Services

[Sergio Costas]

I just finished my first module, now I am working in my second module and realize I am gonna need a service from the first module, I was wondering if I can Provide it in the @NgModule({providers}) list of the second module, I am afraid angular creates two instances of the service if I provide it in two modules.

Hi Sergio,

That is exactly what will happen. Use `{provideIn:root'}` on your services, and don't put them in modules. This will make them "globally" to your app, and the CLI is smart enough to bundle them in the most efficient way.
