I'm trying to create a system with couchdb@2.X and pouchdb@6.4.2, and I'm struggling to make the authentication code with db-per-user, I understood the general idea (kind of) and trying to search for an example or to fix my code, here is what I've did until now:

import Injectable from '@angular/core';
import PouchDB from 'pouchdb';
import PouchAuth from 'pouchdb-authentication';
import syncResult from './../../models/syncResult'
import credentials from '../../models/credentials';
PouchDB.plugin(PouchAuth);

/*
 Generated class for the PouchDbServiceProvider provider.

 See https://angular.io/guide/dependency-injection for more info on providers
 and Angular DI.
*/
@Injectable()
export class PouchDbServiceProvider {

 url:any;
 private localDB: any;
 private remoteDB:any;
 username: string;
 password: string;
 constructor(private pendingSync: Promise<syncResult>) 
 


 singUp(user,pass)
 this.teardown();

 let options = 
 live:true,
 retry:true,
 continuous:true,
 auth:
 username: user,
 password: pass
 
 

 this.localDB = new PouchDB(this.getDBname(user));
 this.remoteDB = new PouchDB('http://localhost:5984/'+this.getDBname(user),options);
 this.localDB.sync(this.remoteDB,options);
 

 private getDBname(userIdentifier:string)
 var dbName = userIdentifier.toLowerCase().replace(/[^a-z0-9_$()+-]/g, "-");
 return (dbName);
 

 public teardown()

 if(!this.localDB)
 return;
 
 this.localDB.close();
 this.localDB = null;
 this.remoteDB.close();
 this.remoteDB = null;
 

Above is the provider that deals (or had to) with the sync between local and remote. The error I have is next:

 Error: Uncaught (in promise): Error: StaticInjectorError(AppModule)[PouchDbServiceProvider -> t]: 
 StaticInjectorError(Platform: core)[PouchDbServiceProvider -> t]:

I know there are many mistakes but I couldn't find some recent help, all the posts I see are old or not clearly documented ( or I'm stupid, if this option, show me the right way haha)
