AngularFireAuthModule and AngularFireDatabaseModule add a lot to final javascript bundle size

[asgarli]

I've noticed that AngularFireAuthModule and AngularFireDatabaseModule add a lot to my final javascript bundle sizes, around 120kb and 200kb respectively. Is that expected behavior, or am I doing something wrong? I'm using latest Angular, so AOT is enabled.

Version info

Angular: 5.1.0

Firebase: 4.8.0

AngularFire: 5.0.0-rc.4

Other (e.g. Ionic/Cordova, Node, browser, operating system): Windows 10, NodeJS 8

How to reproduce these conditions

Steps to set up and reproduce

Create a sample Angular project and add AngularFireAuthModule and AngularFireDatabaseModule

Expected behavior

Smaller library sizes

Actual behavior

• AngularFireDatabaseModule adds around 200kb to final output size
• AngularFireAuthModule adds around 120kb to final output size

Might be because of firebase/firebase-js-sdk#332

Yeah, this is upstream; we'll need the Firebase JS SDK to become more modular to allow the package size to be reduced further. There are conversations going on here but we don't have anything to announce yet.

Can we keep this bug open to track the upstream dependencies?
