I had the same issue but it's solved now:

1. change

getMessages in chat.service.ts to be like this getMessages():FirebaseListObservable<ChatMessage[]>{ return this.db.list('Messages', { query :{ limitToLast:25, orderByKey:true } }); } 2. in chat.service.ts and app.module.ts you have to change import {AngularFireDatabaseModule} from 'angularfire2/database'; //to be like thisimport {AngularFireDatabaseModule} from 'angularfire2/database-deprecated';

Hi @anonnoisy, @anthony-coplo, @JBuckGuy, @sameeranihathe Look at this https://github.com/wesdoyle/base-chat/issues/10#issuecomment-459274318

AngularFire has moved, we're now @angular/fire you have to use '@angular/fire/database-deprecated' in place of 'angularfire2/database-deprecated' or 'angularfire2/database' This worked for me.
