How To Get Total Value From MongoDB And Display At Frontend In Mean Stack

Question

I'm new at Mean Stack, I'm trying to get the total value from Database MongoDb using backend and Display at Frontend. Here is my code.

mainController.js

exports.getQrRecord= function(req,res){
  
          
  Animal.count( {animalId}, function(err, result){
    console.log('count QR',count);

    if(err){
        res.send(err)
    }
    else{
        res.json(result)
    }
 
 })

}

main.service.ts

getqrTotal(){
  return this.http.get(this.baseUri+'/qr');
}

main.routes.js

router.get('/record',qr_controller.getQrRecord);

main.component.ts

getQrRecord(){
    this.logservice.getqrTotal()
    .subscribe((data)=>{
      console.log("QrRecord "+data)

      if(localStorage.getItem('Institution')=='kyls')
      {
        this.qrs=data;
      }
      else{
      this.qrs=data;
     
        
      
      console.log(this.vt)
      this.qrs=this.vt;
    }
    }

    })
  }
