services derived from other services

[bazo]

in nette you can write this

routerFactory: App\RouterFactory
router: @routerFactory::createRouter

i dont think this is possible with dependency-injection?

there's many packages that just expose their classes, rarely you can directly instantiate them

something like this would be really nice

{
    "services": {
        "barista": {
            "service": "barista",
            "instantiate": false
        },
        "router": {
            "service": "@barista.Router"
        }
    }
}

I didn't implement everything from nette di yet, but I definitelly want, so this (@routerFactory::createRouter) is next thing what I want to add.

You are also right with instantiating libraries in js, so I created this issue: #6.

And your last example. Am I right if I say that @barista.Router will access Router property in barista object? I'm just asking because I know this dot syntax from accessing services in extensions in nette di.

many libs export more than on class/function, then you access which one you want with . and instantiate it yourself.
this is the js code

var Router = require('barista').Router;
var router = new Router;

Okay, this shouldn't be a problem

Accessing properties (like @barista.Router) will also have to be with ::, because you can access services also with their paths:

di.get('$path/to/barista.js.Router');     // parsed js: barista.js.Router

so because of this, it will have to look like this:

di.get('$path/to/barista.js::Router');    // parsed js: barista.Router
