Iteration of Object of arrays of objects Angular4

Question

I need to iterate Object of array of objects in anchor tag. Following is the format of my code

{"1":{"uri":"test1","name":"test1","icon":"http:\/\/dummyurl\/images\/icons\/test1-icon.png","application_id":1},"2":{"uri":"test2","name":"test2","icon":"http:\/\/dummyurl\/images\/icons\/test2-icon.png","application_id":2},"3":{"uri":"test3","name":"test3","icon":"http:\/\/dummyurl\/images\/icons\/test3-icon.png","application_id":3},"4":{"uri":"test4","name":"test4","icon":"http:\/\/dummyurl\/images\/icons\/test4-icon.gif","application_id":4},"5":{"uri":"test5","name":"test5","icon":"http:\/\/dummyurl\/images\/icons\/test5-icon.png","application_id":5}}

.ts file

this.applicationService.getApplication(id)
    .subscribe(applications => {
    this.applications = applications.response;});

html

<a class="dropdown-item" href="#" NgForOf=" let obj of applications">
    {{obj.name}} </a>

I am stuck in this from last 3-4 hours. Any help will be appreciated.

Take the time to format your code and question correctly before posting. Also, you have not explained what is not working with the code you posted or what you did to solve it or what your exact confusion is. — takendarkk

You can loop through them using Object.keys(apps)

this.applicationService.getApplication(id)
  .map(result => result.response)
  .subscribe(apps=> {
    this.applications = Object.keys(apps).map(k => apps[k])
   });

HTML

<div *ngFor="let app of applications">{{app | json}}</div>
