Q:

Angular 6 Observable and subscribe

I have some data in angular services coming from REST API
info.services.ts
getCustomerDetails() {
   this.http.get(this.localUrl + this.customerUrl + this.options).pipe(map((response: Response) => response.json()))
}

my homepage.ts
getData(){
  this.infoServices.getCustomerDetails().subscribe(data=>{
    if(data) {
      this.name = data[0].customerInfo.name;
    }
  })
}

and my home.html
<input type="text" value="{{this.name}}" formControlName="name" />

my question is there any better way to fetch data instead of doing data[0]?
endpoint:
router.post("/request/customer", (req, res) => {
    var pendingRequest = new Customer({
        name: req.body.name,
        age: req.body.age,
        isNewCustomer: true,
        requestInfo: {
            customerType: req.body.customerType,
            sendTo: {
                email: req.body.sendTo_email,
                company: req.body.sendTo_company
            },
            returnTo: {
                email: req.body.returnTo_email,
                company: req.body.returnTo_company
            }
        },
    });
    pendingRequest
        .save()
        .then(result => {
            console.log(result);
            res.status(200).json({
                message: "Handling POST request to /pending",
                createdRequest: result
            });
        })
        .catch(err => {
            console.log(err);
            res.status(500).json({
                error: err
            });
        });

A:

I have found the solution, so in ts file:
customerData:any = []
    getData(){
    this.customerData = [];
      this.infoServices.getCustomerDetails().subscribe(data=>{
        if(data) {
          this.customerData = data;
        }
      })
    }

and in your html template simply
<div *ngFor="let data of customerData; let i = index">
{{data.name}}
</div>
