rollup: Use of eval is strongly discouraged, as it posses security risks
This must be error in firebase node_module! I can't understand what's going on.
It's working When I remove firebase.initializeApp(config)
But, having same error on adding above.
Using Firebase v3 in Ionic2 Via NPM is not working at all!! Had lot's of problems in their node module.
So, I found a solution.. follow the link below, where discussion has been made for similar problem. https://forum.ionicframework.com/t/is-it-possible-to-use-firebase-v3-in-ionic-2/54387
