Application should have app.repository() API

[b-admike]

#491 Per @bajtos,

It would be nice to introduce app.repository API to take care of this.

There should be a way to bind multiple repositories (implementation tbd) -- This is just a shorthand of bind().toClass.

Implementation Suggestion: Introspect the name of the repository and use that as the key. User can also supply a string the repository should bind to (similar to how .bind() works).

Acceptance

• Implement app.repository(AccountRepository)
• Allow components to export repositories
• Testing (If test for bind exists then add similar tests but using app.repository()) otherwise add new tests.
• Update Docs
  • https://github.com/strongloop/loopback-next/wiki/Using-Components
  • https://github.com/strongloop/loopback-next/wiki/Writing-Components
  • possibly other places too

app.repository(AccountRepository);

The argument should be strongly typed to a base Repository interface, which is something that we cannot achieve via bind().toClass(), at least not now.

Instead of importing the repository class and binding it to a key on the app instance.

app.bind('repositories.account').toClass(AccountRepository);

@bajtos feel free to edit if I misunderstood.
