This project is for integrating ionic2 with angularFire2 which has adapted angular2.
Following instruction at : https://angularfire2.com/api/
Start from step 2, and used command of
npm install firebase --save
npm install angularfire2 --save
Install typing
npm install typings -g
typings install --save firebase
Skipped step 4 as cannot find ember-cli-build.js
angularFire.database.list() not angularFire.list().
Other instructions followed http://www.masteringionic2.com/blog/2017-02-23-integrating-firebase-into-an-ionic-2-app-with-angularfire2-part-1/
Conclusion: AngularFire2 may be a great tool to work with firebase, but it requires too much work to set it up. Besides, I believe using firebase JS SDK is quite easily. So I prefer using firebase JS SDK.
For future using, need to implement read and write.
